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

Features:

- [High quality 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.

Specifications:

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.
