the pin and box ends to avoid bodily harm from pinching or severing.
Do not allow the box end shoulders of drill rods to be worn to a sharp edge. This may
represent a cutting hazard in addition to representing a severe reduction in the rod
joint’s load capacity which is an accidental separation hazard.
Always reduce the drilling capacity proportionally to the amount of wear measured
as box end wear increases. The use of a Boart Longyear box shoulder wear gauge
is strongly recommended to quickly evaluate box end wear (see page 48 for ordering
details).
Rods must be closely inspected for burrs caused by repeated use of wrenches and
clamps or jaws, burrs pose a cut or snag hazard and should be removed immediately.

MAKING AND BREAKING DRILL STRING
Stabbing
Wireline drill rods and casing provide very little radial clearance when first
inserting a pin end into a box end (stabbing). If the pin end is not aligned, it
will stab into the box end shoulder causing permanent damage regardless
of design or heat treatment. This damage will create leakage ranging from
APPLICATION
Once the face of the pin end shoulder is even with the face of the box end
shoulder, the pin end should be lowered slowly into the box until the stab flank
of the pin thread mates against the stab flank of the box thread. If the pin is
not in true vertical alignment over the box or if the joint has insufficient taper
to allow the first turn of pin thread to clear the first turn of box thread, the pin
thread crest may wedge or ‘jam’ against the box thread crest or begin to cross-
thread. Rotating the connection counter-clockwise ¼ to ½ turn will correct the
misalignment.
Once successfully lowered, rotate the stabbing rod by hand to ensure proper
thread engagement (see make-up). It is recommended that a stabbing guide
be utilized (e.g. Boart Longyear hoist plug and water swivel adapter subs have
a bull nose lead-in feature to prevent stabbing damage).
Make-Up
Wireline rods and casing make-up by slowly rotating the pin clockwise into
the box (right hand threads). On most drills, this must be done at a very low
rotation (e.g. 10 RPM or less) to avoid applying extraneous torque due to the
inertia of the drill head. For example, a 45 kg (100 lb) drill head rotating at 100
RPM can apply an extra 1350 Nm (1000 ft-lb) or more of inertial torque when

BOART LONGYEAR GLOBAL PRODUCT CATALOGUE | CORING RODS AND CASING | 10-2008V
MAKING AND BREAKING DRILL STRING
Lowering/Inserting
The drill drive and hoist sheave must be aligned with the center line of the
hole to prevent undue bending and drag. The drill must also be well secured
to the casing, ground or work face to ensure it does not load the rod string or
become misaligned.
APPLICATION
Adjust hollow spindle drive chucks or feed rollers to ensure that contact
pressure is not permanently deforming or bending midbodies, especially in the
case of light weight rod strings.
In down-holes always lower the rod string with the inner tube assembly
latched in position. The inner tube assembly will act as a check valve
in case the rod string is accidentally dropped.
Break-Out
Theory and laboratory tests show that break-out torque should be 70-80% of
the greater of make-up or drilling torque applied to each joint. Despite this,
breaking-out may be problematic due to adhesion wear or as some drill rigs
do not have the same load capacity in breaking as they do in making-up
or drilling. Additionally, during drilling the joints may be subject to vibration
and loss of thread compound reducing the frictional resistance and allowing
incremental make-up. Note that a poor choice of compound will contribute
to this effect as well. This may result in a break-out torque requirement that
exceeds the original make-up applied. This can be overcome utilizing the
same effect by applying a slight percussive blow to the side of the box with
a rubber mallet or similar non-damaging tool. Do not use a metal hammer
or similarly hard objects. They will affect material properties in the impacted
area and potentially cause fatigue failures and may void the Boart Longyear
warranty.

On down hole applications of significant depth, prior to breaking-out, ensure
that the drill rig foot-clamp is holding the rod string weight and that any

tension across the joint (between the drill head and foot clamp) has been
relieved. This eliminates undue thread wear and a potential safety hazard on
deep holes; the pin should not ‘jump’ out of the box on break-out.
Once the threads have disengaged, the pin can be slowly lifted. Cleaning and
re-lubricating is recommended to maximize wear life.

• Drill rods and casing are packaged and sold in “bundles” which
offer product protection during shipping and handling.
• Protective cardboard caps cover box and pin threads sealing in thread lubrication.
• Heavy duty galvanized hexagon bundle end caps protect the drill rod ends.
• Drill rods are coated with rust inhibitor to reduce surface oxidation during
shipping. When storing rods for long periods of time, it is recommended
you reapply a rust inhibitor to protect the rods from oxidation.

Inspect used rods for bent midbodies regularly. Discard bent rods immediately as these cause
vibration and can hamper drilling performance. Restraightening of rods is not recommended
as this further reduces the bend strength of the midbody and bending will likely reoccur (see

CARE AND HANDLING
CARE AND HANDLING
Thread Wear
The wear of sliding steel-on-steel surfaces, such as in a rod or casing joint, is well defined in
engineering literature. Galling is the common industry term given to thread wear which mainly
consists of adhesion and abrasion wear as a result of making and breaking (see glossary). While
some wear can be tolerated without compromising performance, worn surfaces are prone to further
wear. Unattended, the degree of wear can worsen to the point where it can cause premature failure
or, in the case of mating surfaces of similar hardness, seize the joint. Alternatively, a worn thread
can damage a good thread.
The rate of wear to be expected in a sliding metal-to-metal system can only be determined by
considering all of the following variables:
• Lubrication or wear factor: published values are greater for poor lubrication; less
for mating surfaces of dissimilar hardness (see lubrication and cleaning)
• The hardness of the softer surface
• The distance of contact slide
• The contact load or pressure
Another source of rod joint wear is worn accessories. All threaded accessory equipment, such
as Kelly (drive) rods, drive head adapter subs, hoist plugs, water swivels and cross-over adapter
subs should be inspected prior to use to ensure they are in good condition. Use only genuine Boart
54 Longyear accessories to ensure proper fits and maximum wear life. Boart Longyear tooling and
gauging adhere to an uncompromising global standard.

CARE AND HANDLING
In typical joints, it is inherent for the box and box end shoulder to elastically deform radially
or ‘bulge’. This is due to radial and hoop stresses (see glossary) imposed by conventional
threads which add to drilling load stresses. This is evident by a thin section in the box shoulder
and/or a small polished area on the side of the joint where thread engagement begins. As the
wear progresses, the box becomes weaker and the deformation more pronounced, increasing
the wear rate. RQ® style joints however, mimic the load response of a solid tube in that radial
and hoop stresses imposed by the thread subtract from drill load stresses, virtually eliminating
“bulging”.
It is inherent for a rod string to respond to significant drilling loads and rotation in a three
dimensional corkscrew shape, a phenomenon first identified and defined by Boart Longyear as
‘helical whirling’. As loads or rotation increase, the contact pressure between the string and the
hole increases contributing to an increased midbody wear rate.
Given sufficient contact pressure and speed, the heat generated between the rod string and
casing or hole can cause heat-check cracking (see glossary) which ultimately appears as an
axial crack, typically on the box end.
The bending stresses associated with this helical whirling become significant under high load
or rotation, especially in oversize holes or ‘caves’, and may cause permanent bending of the
string. Boart Longyear drill rods incorporate enhanced tubing processing which doubles the
bend strength of the midbody virtually eliminating permanent bending.

The use of ‘rod grease’ to reduce friction between the rod string and the casing or hole is
common (see lubrication and cleaning) however the only effective solution to reduce midbody

CARE AND HANDLING
CARE AND HANDLING
Due to the reduced cross-sections of material in the threaded ends, the joints between mated
rods in the string are significantly weaker than the rod midbodies – regardless of heat treatment
or thread design (despite the interlocking thread, RQ® joints for example, are weaker and are not
stiffer than their midbody). Also, joints are pre-loaded (make-up) and have interference fits which
further reduce the deviation capacity of the joint.
A further limitation on the ability of a drill rod joint to perform through a bend is due to a peculiarity
of the steel material itself. If there is a constant tension load applied in addition to a cyclical load,
the fatigue strength is even further reduced. In the case of drill rod joints, if the joint is properly
made up the pin end will always be under a greater tension load than the box end (see make-up
torque). As a result, the pin end is the weakest part of a drill rod and is the typical location of failure
under an excessive cyclic load. Boart Longyear utilizes a full scale cyclic bend load test to evaluate
joint designs and to ensure manufacturing quality.
A fatigue failure crack always occurs perpendicular to the cyclic load or stress. Therefore the
most common failure is a circumferentially oriented crack which indicates that the cyclic load or
stress was axially oriented which

Bend stresses have exceeded the fatigue strength of the joint. Bend stresses are caused by excessive steering, excessive
hole deviations or caves, or helical whirling (see midbody wear). Do not exceed deviation ratings. This may have been
compounded by high pullback loads at depth or excessive make-up. Plan deviations to occur at portions of the string that
are under low pullback (e.g. avoid the upper portion of a deep hole string).
Fatigue strength may have been exceeded in previous application and joint has now reached limit (see memory and fatigue

GLOSSARY
Adhesion Wear
This type of wear involves the adhesion (micro-bonding or micro-welding) of very small areas
between the contacting surfaces of mating threads with similar hardness. The bonded areas can
fracture off, generating wear particles, or transfer to the mating surface. Wear particulate can
then bond together and grow in size, producing larger scale wear. In the extreme case, adhesion
wear can seize a joint (see seizure). The rate of adhesion wear decreases as the surface
hardness increases. Adhesion wear will not occur if the thread compound prevents contact of
the surfaces (see lubrication and cleaning).
Abrasion Wear
This type of wear involves gouging and polishing of a surface by wear particles or foreign
debris. Wear particles are either repelled or embedded into the subject surface but do not build
or micro-weld avoiding joint seizure (see adhesion wear). The rate of abrasion wear is directly
proportional to the contact pressure and the sliding distance between the mating surfaces. The
rate of abrasion wear decreases as the surface hardness increases. Also, the rate of wear is
GLOSSARY
less between mating thread surfaces of differing hardness. Abrasion wear will not occur if the
thread compound prevents contact of the surfaces (see lubrication and cleaning).
Fretting
Small relative cyclic movement between two surfaces in contact. Fretting produces pitting wear
(a form of adhesion wear) which can lead to fatigue failures. The wear rate increases with
amplitude but not with frequency (see fatigue strength).
Galling
Large scale (visual) damage to both mating thread surfaces in a joint caused by small areas
of plastic deformation (adhesions or transfers, see adhesion wear) that interfere with sliding
which can lead to seizure. Galling resistance is a function of the mating surfaces, not of a single
surface, and is typically not seen on Boart Longyear drill rods. The term galling may also be
applied to significant abrasion wear although this is not technically correct (see abrasion wear).
Heat-Check Cracking
This is axial cracking (crack works from the outside surface in) resulting of the rapid expansion of
a thin layer of brittle surface material that was hardened by the heat of friction (e.g. rods rubbing
64
on casing or hole) and then rapidly quenched by drilling fluid and the cooler material underneath.
Hydrogen Embrittlement
Copyright © 2008 Boart Longyear. All Rights Reserved.
Hydrogen has damaging effects on all metals, including reduction of fatigue strength,
enhancement of crack propagation and corrosion cracking. Hydrogen may be encountered in the
hole, or may be created by reactions with acidic fluids in the hole or generated by corrosion.
The absorption of hydrogen in metals is enhanced by sulphide-bearing waters (H2S) and by
thread compounds containing metal particulate.
Inertia
The force developed by the momentum of a moving or rotating mass (such as a rotating rod
string or a drill head) which resists acceleration or deceleration.
Inertial Torque
Inertial torque is the make-up induced when the joint of an added rod is fully made up and stops
abruptly against the inertia of the rotating drill head.

GLOSSARY
Joint Seizure
Mating thread surfaces are not able to move relative to each other as a result of increased friction due
GLOSSARY
to galling or adhesion wear (local solid-state welding, “micro-welding”) potentially preventing break-
out of a joint.
Memory
Fatigue damage is cumulative. All steels have a limit to the number of applications or reversals of
an excessive repeating load which is commonly referred to as memory. For example, a rod may
successfully complete one demanding application and then fail in a future less demanding application
when the limit is finally exceeded with only a few more cycles of excessive load. The generally
accepted limit for steels to an excessive repeating or alternating load is three million cycles. At 500
RPM, this is 100 hours of drilling which could easily traverse more than one job where the excessive
loading is not continuous (larger sizes are more prone to memory failures as they run at lower RPM
and have inherently higher bend stresses). Memory failures can be caused by any excessive load
that fluctuates due to rotation (e.g. a bend load, a hoop stress due to large foreign debris particles,
stabbing damage, etc).
Spin Outs
Sudden break-out of joints due to the inertia (see inertia) of a rotating rod string under deceleration.

Stress

yield strength, beyond which deformation is permanent. In a drill rod, there are three components or
directions of stress:
• Axial stress
• Hoop stress
• Radial stress
These components add together according to vector addition to a total stress value known as the
principle or Von-Mises stress. The axial stress is directed parallel to the rod longitudinal axis and is
a direct result of drilling or bend loads. The hoop stress is directed circumferentially around the tube
and perpendicular to the rod axis. In a rod joint, hoop stress is induced by the thread form and adds
to the total stress – except in RQ® style joints which reduce the total stress – mimicking the midbody.
The radial stress is directed radially inwards or outwards from the rod longitudinal axis and is typically
not significant, except under extraordinarily high fluid pressures.
