Dormer High Speed Cobalt Drill Bit 165mm Overall, 8mm Shank Size A9408.0

Dormer A9408.0 High Speed Cobalt Drill Bit with 165mm overall length and 8mm shank diameter is engineered for precision drilling in industrial manufacturing, mechanical engineering, and metal fabrication environments. The drill bit’s high speed cobalt material offers superior hardness and heat resistance, making it suitable for drilling deeper holes in most materials up to 10 times the diameter without frequent pecking.

The design includes 10 spiral flutes forming a parabolic flute pattern to facilitate efficient chip removal, thereby reducing heat build-up and enhancing tool life. A 130° special drill point geometry provides excellent centring and reduces thrust forces during use, improving accuracy and reducing wear on the drill and workpiece.

The drill bit features a cylindrical shank with a bright, uncoated finish, ensuring firm grip and compatibility with standard chucks. Its thicker web design offers increased structural strength, minimizing the risk of drill breakage under heavy-duty conditions.

Manufactured to DIN340 standards, this drill bit is ideal for industrial, manufacturing, construction, and toolroom applications where precision and durability are critical. It suits use in machining deep holes in metals and alloys.

High speed cobalt material ensures durability and heat resistance. Ten spiral flutes enhance chip evacuation for better performance. 130° drill point angle for improved centring and reduced thrust. Cylindrical shank with bright finish provides secure attachment.

Complies with DIN340 quality standards.
