Product description

Sharp and durable, easy chip removal, and further improve processing efficiency.
Material HSS-Co M35 Cobalt
Shank type straight handle
Quantity 13/19/25PCS + plastic box

note:
When drilling metals, cobalt bits require lower RPM. The suggested RPM is for reference only. It may vary for different materials. You can start with a lower RPM and then slowly adjust it to higher. Once the drill bit can enter the workpiece. The adjustment should stop.

feature:
● M35 cobalt. 5% cobalt is added to improve hardness and heat resistance. Rockwell hardness can reach up to 67. It has a faster cutting speed and a longer service life, which is 12 times that of an average HSS bit.
● Self-centering. The guiding separation point of 135° rapid cutting is automatically centered and can be penetrated quickly under low pressure. The straight shank can be firmly fixed and accurately centered, suitable for standard drill chucks and conventional circular chucks.
●Efficient drilling without walking. Remove debris and particles faster and easier.
●The lowest drilling cost. The solid cobalt steel drill bit can be reground.
●Split point. Drill directly to the required size without pre-drilling
●Fully grounded. Heavy-duty fully ground body structure with minimal burrs and precise diameter.
●Drills for metal. Suitable for drilling non-heat-treated metals with hardness less than HRC38, such as stainless steel, copper cast iron, galvanized pipe, iron and aluminum alloy. Not suitable for hardened steel/high carbon steel. If it cannot penetrate, try to adjust the speed.

Package Included:

13/19/25 PCS M35 Cobalt Drill Bit Set
