Dormer High Speed Cobalt Drill Bit 70mm Overall Length 3.18mm Diameter A9001/8

Dormer A9001/8 High Speed Cobalt Drill Bit with a 3.18mm diameter and 70mm overall length is a premium-quality cutting tool engineered for precision drilling in industrial environments. Manufactured from high speed cobalt, this drill bit provides superior heat resistance and wear durability, making it suitable for machining deep holes in a variety of metallic materials.

The drill bit features a cylindrical shank of 3.2mm that fits securely in standard drill chucks, supporting reliable operation and reduced vibration during use. It has 6 helical flutes with a parabolic flute design that effectively evacuates chips and reduces the need for frequent pecking even when drilling holes up to 6 times the diameter of the bit.

A specialized 130° drill point angle enhances centring accuracy while reducing thrust forces, allowing easier penetration and extended tool life. The bright (uncoated) finish ensures smooth cutting action. The thicker web structure of this jobber length drill increases structural strength, thereby minimizing the risk of breakage under demanding work conditions.

Manufactured according to DIN338 standards, this drill bit is suitable for various industrial, mechanical, and manufacturing applications where precision and tool reliability are critical.
