Description:
99Pcs M35 Cobalt Drill Bit Set 1.5-10mm HSS-Co Jobber Length Twist Drill Bits For Stainless Steel Wood Metal Drilling.

Features:
- [fine material]: 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.
- [Accurate Card Position]: 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.
- [Efficient and fast]: High-efficiency drilling can be carried out without walking. Remove debris and particles faster and easier.
- [Low cost]: The lowest cost of drilling each hole. The solid cobalt steel drill bit can be reground.
- [Split point]: You can drill directly to the required size without pre-drilling.
- [Widely used]: 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.
