Abstract | The utility model relates to a high -speed steel rail bores. Still do not have a structural design equitable at present, long service life both can be in operation under the state of cooling, again can be at continuity of operation's under the no state of cooling high -speed steel rail bores. The utility model discloses a handle and cutter body, the one end of cutter body and handle are fixed, and the other end of this cutter body is provided with cutting edge and chip removal mouth, the outer wall of cutter body is provided with the helicla flute, and its characteristics are: the cutting edge includes outer cutting blade and interior cutting blade, be provided with on the interior cutting blade and be used for forming the chip dividing groove of forcing to divide bits point. The utility model has the advantages of reasonable structure design, two layers of geometry carry out the layering cutting, and through high tooth centering, low tooth divides the bits heat dissipation with the chip dividing groove combination, improves life, both can be in operation under the state of cooling, and again can be at continuity of operation under the no state of cooling. |
