HSSE-PMC
Extra high performance tools produced from advanced powder metallurgical
compacted high speed steels.
PMC steels are made by melting high speed steel by the normal method, but
instead of casting conventional ingots, the molten metal is “atomised” to fine
particles in a stream of inert gas. The particles are then isostatically pressed at high
Reamers
temperature and pressure followed by hot forging and rolling. This gives a fine
structured homogeneous material.
Unlike conventionally produced High Speed Steel the material is chemically and
metallurgically uniform on the cross section. This gives the best possible
combination of hardness and toughness in finished heat treated tools.
The improved structure allows higher alloy contents, increasing wear resistance and
hot hardness with minimum loss of toughness and resistance to chipping of the
cutting. edge.
The uniform carbide dispersion at the cutting edge reduces risk of grinding burn
Taps & Dies
PMC is a general purpose grade suitable for tools subject to high wear and
torsion/impact conditions.
PMC Co is similar to PMC but the addition of cobalt increases hot hardness and
resistance to cutting edge breakdown due to heat generated by high speed or
abrasive cutting.
APPLICATIONS
Drilling, tapping, reaming and milling, hard, tough or abrasive materials. Tapping
aerospace materials, high tensile steels, Nimonics, Waspalloys, Titanium Alloys and
wherever high cutting forces are encountered.
Milling Cutters DIN
Machining conventional alloy steels and cast irons with PRESTO PMC. Tools can
produce longer tool life or allow faster machining so reducing cost per hole.

For extracting broken screws and studs, drill a hole in the screw, as shown in the
table below. Insert the appropriate PRESTO SCREW EXTRACTOR and turn anti
clockwise. The corkscrew teeth will release the broken screw, leaving the original
thread in the hole undamaged.
For use on medium tensile strength screws and studs, use the drill size
recommended in table A.
For screws and studs of high tensile strength, 75 tons/Sq in. or over, use drill size
recommended in table B.

Carbon Steel Cut Thread Taps are produced to the cut thread tap class. This class
has a far wider manufacturing tolerance than precision taps and is suitable for only
‘free fit threads’. Carbon Steel Cut Thread taps are unsuitable for machine use
except at very low speeds and on very soft materials and are generally used for
hand tapping.

The nominal size is of the pipe fitting and not the size of the tap. These taps are Lubricant
sometimes described as full thread taper taps or conical thread taps and normally Good tapping results can only be achieved by using the correct lubricant eg.
one tap per size is supplied. Taper pipe thread taps are normally supplied with sulphurised threading oil which cools, lubricates and helps wash away threading
straight flutes and only one lead of 17˚, but available with taper, second and chippings and makes the job of threading easier.
Re-sharpening
Sizes given permit direct tapping without reaming the hole, but only give a full
thread for the first two or three threads. A dull tap may produce undersize or oversize holes with poor finish. Normally
smaller taps need regrinding on the chamfer only; larger taps may also need
regrinding in the flutes. Regrind only on a tool and cutter grinder and duplicate the
grinding (as near as possible) to be found on a new PRESTO tap of the same size
and type.

approximately 30° helix angle and are produced to slot drill tolerances.
The end teeth are ground to allow both plunge cutting and rapid traversing giving the accuracy of
a slot drill and the versatility of an end mill and are suitable for use on a wide range of materials.

The No. 480 Geared Receder Diestock is designed for easy working by one operator.
The dies cut either TAPER or PARALLEL threads. The change from TAPER to PARALLEL screwing requires a small adjustment of the control screw – see instruction card for full
details. The pillars of the stock are so marked to give correct length of thread in relation to the pipe diameter screwed. When screwing threads, the diehead revolves whilst the
driving pinion remains fixed in the most suitable operating position. Each set is supplied in an individual, non returnable wooden box for easy handling and storage.
The No. 480 diestock is available in two sizes, and dies are available for BSPT or NPT threads. With the 4801 Diestock, one set of dies will screw 2.1/4 in to 4 in pipes.
The 4803 Diestock has two sets of dies to screw 2.1/4 in to 6 in pipes and the 4802 Diestock is available with one set of dies for screwing 4 in to 6 in pipes only.

substrate is less susceptible to damage and retains sharper cutting edges which do not require any edge reinforcement.
PRESTO supply the highest quality PVD Coatings on all types of rotating cutting tools in the following specifications:
Reamers
The improved chip flow and surface finish also enhances the size of
hole drilled. Speed can be generally increased by 1.6 times.
It has become the preferred coating for milling cutters but can offer
additional wear resistance on tapping. Speed can be 1.8 to 2.2 times
and feed per tooth increased by 5%-10%.

A thin radiused wheel can be used to grind grooves across the cutting face, which assists chipbreaking. Reducing the peripheral speed

cutting lips to become concave which weakens the outer corners. It is preferable to use specially designed drills for the more difficult
materials.
Point Correction
The face of the flute along the cutting lip is ground to reduce the helix angle for brittle materials. A similar technique can be used to
correct convex cutting edges. It is important that the circular land at the corners is not ground away.
Pipe Threading Tools
Split Point
On thick web heavy duty drills the chisel may be too wide for successful thinning and better results are obtained by grinding across the
chisel edge to produce additional cutting action at the centre.
When drilling thin materials the chisel edge may break through before the outer corners are cutting. This causes burrs on the underside
of the work, snatching of the drills with possible breakage and out of round holes. Better results can be obtained by using a flatter point
of 140° or more and thinning the chisel edge almost to a point to reduce end pressure and aid penetration.

COMMON REASONS FOR DRILL FAILURE
Reamers
1. Oversize Hole
a. Lips unequal in length.
b. Chisel edge not central.
c. Machine spindle out of true.
Milling Cutters BS
e. Surface cracks on flanks of point due to bad point grinding.
4. Broken Tang
The Tang is for ejection purposes only. Allowing torque to be taken by the tang
will result in breakage. Always ensure that the taper socket is free from foreign
matter and damage, so that friction alone drives the drill through the taper of
the shank.
6. Chipping of Lips
a. Lip clearance too great.
b. Work not adequately supported.
7. Breaking of Drill
a. Drill worn or improperly point ground.
b. Drill slipping in drive.
c. Drill flutes choking.
d. Insufficient lip clearance.
Pipe Threading Tools
There are several requirements for an efficient drill, lack of any one of which will
result in higher drilling costs, bad holes and less number holes per regrind.
Correct speeds, feeds and lubricants when drilling are as important as using a
correctly ground drill.
Recommended Speeds (See page 200) & Feeds (See page 204).

REAMING ALLOWANCE
The amount of metal to be removed by the reamer depends on:
1. Application (Hand or Machine).
2. Size of hole.
3. Metal being reamed.
Milling Cutters BS
Recommendations:
1. Hand-reaming allowance approximately two-thirds
machine-reaming allowance.
2. On free-cutting mild steel, machine-reaming allowance guide:
Holes up to 6mm dia, use up to 0.2mm
Holes over 6mm dia up to 12mm dia, use from 0.2mm to 0.3mm
Holes over 12mm dia up to 25mm dia, use from 0.3mm to 0.5mm
Holes over 25mm dia, use from 0.4mm to 0.8mm
3. Usually the more difficult the metal being reamed the smaller the
reaming allowance.

by the International Standard Organisation (ISO).
Blank dimensions shanks and squares are to ISO 529 (Long Shank Machine Taps ISO 2283) with the

The British standard for Taps incorporates all the relevant ISO standards.

Milling Cutters BS
Rp Series Threads (BSPPI Series threads) contained in BS 21. This is an assembly of a parallel internal thread
with a tapered external thread when pressure tight joints are required.
In all three pipe thread series, there is only one class of internal thread fit, and therefore there is only a
requirement for one class of tap tolerance which is Class 2 in the case of the G and Rp parallel internal
threads. Taps for producing the G and Rc series threads will be available from stock from manufacturers at a
list price, but taps for producing Rp series threads will normally only be made to order by manufacturers.
(American pipe thread taps ie. NPT, NPS etc. will be supplied with dimensions shown in BS 949: 1951, BS
949: 1969 and ANSI 94.7: 1971.)
Tap Sets of 3
Presto High Speed Steel Ground Thread Straight Flute Taps to BS 949/ISO 529 are also available in sets
of 3 per box. Each set contains 1 each Taper, Second and Bottoming leads of identical size. See page 97.

In BS 949 there are three ground thread tap classes for both imperial and metric sizes. There is an additional cut thread class.
In the respective nut standard BS 1580 (unified) and BS 3643 (metric) each commonly used nut class has zero minimum clearance for pitch diameter, i.e.
minimum size is basic. In the metric series there is also a G tolerance having positive minimum clearance above basic which gives a specified oversize for plating
purposes - see fig. 2.
The relationship of tap size and tapped hole size is of a general nature since the accuracy of tapping depends upon external factors other than tap size.
Class 1 Tap
Reamers
This is closest to basic, having little wear allowance, and is normally specified for ‘close’ fit threads, e.g. Unified 3B; Metric 4H, 5H.
Class 2 Tap
This is normally specified for ‘medium’ fit threads, e.g. Unified 2B Metric 6H; 4G, 5G.
Class 3 Tap
This is the furthest above basic and used for ‘free’ fit threads, e.g Unified 1B; Metric 7H, 8H, 6G.
All the above tap classes have a similar close manufacturing tolerance and vary only in their minimum size above basic.
All PRESTO HSS Ground Thread Taps are supplied Class 2 (unless otherwise ordered).

Tapping costs rise rapidly as the percentage of thread increases. For deep hole tapping or average commercial work a thread depth of 60% - 70% will usually provide a
greater strength than that of the mating screw.
Reamers
Lubricant
First class tapping can only be done with a copious supply of the proper lubricant. Use of lubricants is as important as its choice: keep it clean and direct the flow into
the hole being tapped. An ample supply is needed on the cutting edges, not only to disperse the heat but in many cases to assist in the formation and disposal of the
chips.
Re-sharpening
A dull tap may produce undersize or oversize holes with poor finish. Normally smaller taps need regrinding on the chamfer only; larger taps may also need regrinding in
the flutes. Regrind only on a tool and cutter grinder and duplicate the grinding (as near as possible) to be found on a new PRESTO tap of the same size and type.
Speeds
Efficient tapping has its optimum speed - see pages 213-217 for recommended speeds - use these as a guide. Exact figures cannot be given because of variables such as
machineability of material being tapped, condition of machine, depth, pitch and length of thread, holding fixture, etc.
Feeds
When starting a tap do not force or retard, or a bell mouthed hole will be produced with ’thin‘ threads. Allow the tap to find its own lead.
Do not rough out a tapped hole too near to finished size, otherwise the finishing tap will not cut, but rub, inducing work hardening, dull taps and breakages.
When tapping deep holes avoid the flutes becoming clogged with chips - breakage is inevitable in such circumstances. Use one or more roughing taps and a finisher.
The problem of chip disposal is more prevelant in the tap size range 1/2" diameter and less, where flute space is restricted and chip disposal more difficult.
Milling Cutters BS
For this reason spiral pointed taps are available in this range of sizes and are used for through hole tapping only. Sizes larger than 1/2" have sufficient flute space to cope
with chip disposal.
NOTE: Spiral point taps are eminently suited for tapping short through holes.
Hand Taps
For hand tapping, the conventional set of 3 taps with straight flutes is recommended. It is essential that the tap is presented squarely to the work and that taps are
correctly aligned. When these taps are used in a machine it is not usually necessary to use the taper tap.
Serial Taps
On the more difficult to machine materials or on long blind holes it may be necessary to use either two or three serial taps. The tap thread is generally serialized by either
truncating the full form threads or by grinding the full thread form progressively undersize.
Bent Shank and other special long reach taps required for special purpose machines and processes are made to order.
Pipe Taps
The nominal size is the size of the pipe fitting, not the size of the tap, and may be either parallel thread (e.g. BSPF, NPS) or taper thread - sometimes known as full thread
taper taps (e.g. BSPT, NPT (API)). Only two taps, taper and bottoming, are normally used for the parallel thread.
One tap per size is supplied for full thread taper forms.
For use on materials which tend to load the tap, e.g., galvanised pipe, it may be necessary to use a pipe tap with alternate threads removed (interrupted thread).
This is only recommended where difficulty is experienced with standard taps.

Milling Practice
The ease with which material can be milled is dependent on several factors including tensile strength and abrasion resistance. These may be assessed from hardness tests,
material and composition and known heat treatment. Whilst hardness and/or strength is the usual criterion, wide variations in machinability can exist among material
Reamers
The cutting conditions used can be dependent upon requirements for tool life and surface finish and further restricted by rigidity of tool and work piece, lubrication and
machine power available.
In general the harder the materials the lower the cutting speed, but some materials of relatively low hardness contain abrasive constituents leading to rapid cutting edge
wear at high speeds. Feed rates are governed by rigidity of set-up, width and depth of cut, i.e. volume of metal to be removed, surface finish and available machine power.
Taking the above into account, therefore, no one set of feeds and speeds is necessarily correct for a given material.
It is usually preferable to set and maintain a constant surface speed (RPM) for a given material and vary the feed rate within defined limits to obtain the desired objective.
Taps & Dies
Machine feeds is measured in inches or millimetres per minute and is the product of RPM x number of teeth in the cutter x feed per tooth.
All machine feeds should be worked back from the recommended feed per tooth of the cutter. Too light or excessively high feed rates will both cause premature cutter
failure, e.g. very light feeds on work hardening materials will fail to penetrate the work hardened layer and cause cutting edge breakdown. Heavy feeds on hard materials
will cause chipping of the cutting edge and excessive heat generation.
Slender and long shanked cutters are restricted in feed rate due to deflection and wherever possible the largest and most robust tool should be used. This is particularly
important for materials over 300 HB. Steel up to 400 HB is the potential limit for conventional HSS tools. Above 300 HB premium grade cobalt HSS should be considered
for increased life. Above 400 HB high cobalt HSS is necessary.
For softer types of material, cobalt HSS may give increased output by increasing speeds and feeds up to 50%.

feeds and speeds must be reduced. Avoid large overhang of shank cutters.
Adequately clamp the work piece.
(2) Speeds, feeds and lubrication. Consult the foregoing charts and adapt to suit
workshop conditions.
(3) Tool Maintenance. Check tool shanks or bores and machine chucks or arbors
for dirt or scoring before mounting the tool. Badly mounted tools result in lack
of concentricity, poor finish, inaccuracy and poor tool life.
Remove cutters for regrinding at regular intervals before edge wear becomes
excessive. Running dull cutting tools is expensive.

Technical
RPM Speeds are calculated from peripheral Metres per minute as shown in Bold on “Speed M” line. Where it is “12000 rpm”, speed is restricted for bright finish cutters
as few machines have higher spindle speeds. Higher speeds are given for Coatings as modern machines may have high speed spindles. If slower, calculate from
RPM x Feed/Tooth x Number of teeth (3 except on 1mm cutter when only 2). Depth of cut = 1/2 Diameter, Width of cut = Diameter, this may be varied to one dia. in
depth x 1/4 of dia side engagement. Larger amounts of cut will require the reduction of the feed rate, i.e. double the area, half the feed rate. Long series cutters, use half
the feed rates.

6. DELIVERY
6.1 Delivery shall be made by the Buyer collecting the Goods at the Seller’s premises at any time after the Seller has notified the Buyer that the Goods are ready for collection or, if
some other place for delivery is agreed by the Seller, by the Seller delivering the Goods to that place.
6.2 Delivery dates are approximate only and the time for delivery shall not be of the essence.
6.3 Where the Goods are to be delivered in installments, each delivery shall constitute a separate contract. Failure by the Seller to deliver any one or more of the installments or any
claim in respect of any one or more of the installments shall not entitle the Buyer to treat the Contract as a whole as repudiated.

connection with the supply of the Goods or their use or resale by the Buyer and the entire liability of the Seller under or in connection with the Contract shall not exceed the price
of the Goods, except as expressly provided in these Conditions.

be entitled to cancel the Contract and any other contracts with the Buyer or suspend any further deliveries under the Contract and any other contracts with the Buyer without any
liability. If the Goods or any other goods have been delivered, but not paid for, the price shall become immediately due and payable.

as may have been notified. Notice shall be deemed to have been received, in the case of a facsimile, upon transmission and, in the case of a letter, forty eight hours after posting.
11.3 If any provision of these Conditions is held to be invalid or unenforceable in whole or in part, the validity of the other provisions and the remainder of the provision in question
shall not be affected.
