Dormer High Speed Cobalt Drill Bit 8.5 mm Shank Cylindrical 117 mm Overall Length A9008.5

Dormer A9008.5 drill bit is a high speed cobalt (HSCo) straight shank parabolic flute jobber length drill designed for machining deep holes up to six times the diameter in a wide range of materials. Its high performance cobalt construction enhances toughness and heat resistance, making it suitable for industrial, mechanical, manufacturing, and machining applications requiring precision drilling.

The 117 mm overall length coupled with a drilling length of 75 mm allows for efficient deep hole drilling while the 6 helical flutes and parabolic flute design promote rapid chip evacuation, reducing clogging and improving cutting efficiency. The 130° special drill point geometry offers excellent centering capability and lowers thrust requirements, thus increasing operational efficiency and reducing tool breakage risk.

The drill bit’s cylindrical shank provides a secure grip in standard chucks, and its bright, uncoated finish maintains sharpness and cutting accuracy. Made according to DIN338 standards, the tool ensures consistent dimensions and performance quality, ideal for industrial manufacturing, maintenance, and repair workshops.

Manufactured in France, this Dormer drill bit is engineered for robust use in industrial tooling, engineering shops, and mechanical workshops. Its sturdy design minimizes breakage and supports long tool life, contributing to cost-effective machining processes.
