Features:
1. M35 cobalt. Added 5% cobalt to improve hardness and heat resistance. The Rockwell hardness is up to 67. It has a faster cutting speed and a longer service life, which is 12 times that of an average HSS bit.
2. Self-centering. The guiding separation point of the 135° rapid cutting is automatically centered and can be penetrated quickly under a small pressure. The straight shank can be firmly fixed and accurately centered, suitable for standard drill trays and conventional circular trays.
3. High-efficiency drilling can be carried out without walking. Remove debris and particles faster and easier.
4. The lowest cost of drilling each hole. The solid cobalt steel drill bit can be reground.
5. You can drill directly to the required size without pre-drilling
6. Suitable for drilling stainless steel, copper cast iron, galvanized pipe, iron, aluminum alloy and other non-heat-treated metals whose hardness is less than HRC38. Not suitable for hardened steel/high carbon steel. If it cannot penetrate, try to adjust the speed.

Note:
- Cobalt drill bits require slow RPM when drilling metals. The suggested RPM is only for your reference. It may vary from different
materials. You can start from a lower RPM and adjust it higher slowly. Once the bit can get into the workpiece. the adjustment
should be stopped.
