Bit for rotary drilling |
| abstract |
The invention relates to the mining industry and m. used in rotary drill bits. The purpose of the invention is to increase the efficiency of the bit by improving the conditions for cleaning the bottom from broken rock and cooling the cutting edges of the inserts. The bit includes a body 1 and two feathers (II) 2 with carbide inserts 4. A7 form a dissection (P) 3. In P 3 a core-breaking insert 5 is installed, shifted to one of II 2 and lagging behind their tops. (L 2 UE U |
