Cobalt Twist Drill Bits, Ideal for Metal Drilling

The 5% Cobalt M35 High Speed Steel drill bits are brand new and of high quality. Featuring a 135-degree angle point and a straight, round shank, these bits meet ANSI specifications and have a Rockwell hardness of 65-66.

The high-speed steel construction provides exceptional durability, with a hardened and honed cutting edge for sharpness. The staggered cutting teeth ensure a chatter-free design and precise countersinking, leaving a smooth, clean hole.

The split point tip and twist design of these drill bits increase cutting speed while facilitating easy self-centering, preventing the bit from walking. This twist design also allows for quick clearance of chips and particles, resulting in a clean, smooth hole.

Users are advised to handle the drill bits with care and caution to prolong their working life. These bits are not suitable for use on concrete or masonry.

Customers are encouraged to carefully review the detailed product information before purchasing. While every effort has been made to ensure accurate sizing, there may be a 1-2mm variance due to manual measurement.
