Abstract

PURPOSE:To obtain rapid cut and nice finish surface by mounting two chip pockets on a cutting edge part and forming the 1st saw-teethed cutting edge and the 2nd straight edge so that mass of one cut can be increased. CONSTITUTION:A bit is composed of a shank 2 and a main body 3 which is made in one body with the shank and has a cutting edge 4 and a guide part 5. Chip pockets 6, 7 are made on this cutting edge 4 in parallel to the axis and saw teeth 10 are formed on the crest part 9 of the 1st cutting edge 8 mounted between these pockets 6, 7. Then, the 2nd cutting edge 11 is formed in the cutting edge 8 across the poket 7 and the difference between the terminal edge 12 of a guide part 5 facing the cutting edge 8 acorss the pocket 6 of the guide part 5 equipped following the cutting edge 11 and an external circumference 13 at the cutting part 4 makes a mass of cut every rotation. If the cutting edge 8 makes the first rough cut and then the following straight cutting edge makes finish cut, rapid cutting and nice finish surface can be obtained.
