Frequently Asked Questions

What materials are Dormer cobalt drill bits suitable for?

Dormer cobalt drill bits excel when drilling hard materials including stainless steel, cast iron, hardened steel, titanium, and other tough alloys. They're the preferred choice when standard HSS bits overheat or wear too quickly.

How do I identify genuine Dormer cobalt drill bits?

Authentic Dormer cobalt bits feature clear manufacturer markings on the shank, typically including the Dormer brand name and size designation. The distinctive gold or bronze colouring of the cobalt steel alloy is also characteristic of genuine products.

Can Dormer cobalt drill bits be resharpened?

Yes, Dormer cobalt drill bits can be resharpened using appropriate grinding equipment, making them a cost-effective long-term investment for professional workshops. Proper resharpening maintains the original point geometry and extends usable tool life considerably.
