Dormer High Speed Cobalt Drill Bit, 7 mm Size, 109 mm Overall Length, 130° Point Angle, Cylindrical Shank, Bright A9007.0

Dormer A9007.0 is a high speed cobalt drill bit designed for precision machining in industrial and mechanical applications. It features a 7 mm diameter and an overall length of 109 mm, enabling deep hole drilling up to 69 mm length without frequent interruptions. Its high speed cobalt material provides exceptional wear resistance and thermal stability during high-speed operations.

The drill bit's 6 helical flutes are shaped in a parabolic design to facilitate rapid chip evacuation, which minimizes clogging and maximizes drilling efficiency. The bright, uncoated cylindrical shank offers reliable holding and easy tool changes on various drilling machines.

The drill point has a 130° special geometry that improves centring capability and reduces thrust force required, thereby enhancing accuracy and tool life. This design, along with a thicker web, provides added structural integrity to resist breakage under demanding conditions.

Manufactured to DIN338 standards, this Dormer drill bit is ideal for machining deep holes in a variety of materials up to six times the diameter of the drill. It finds extensive application in manufacturing, metalworking, and mechanical engineering industries where precision and durability are critical.
