Rated 5 out of 5 by from Keeps going and going Fantastic drill bit, I was thinking about buying two of these incase one snapped. However, even after drilling 100 or so holes through steel with the occasional snag that wasn't necessary. If you have a job that's likely to test the bit, then buy this.

Rated 5 out of 5 by from Careful may require PPE I thought I'd try these to drill some holes in some 2mm Aluminium, which even though soft can be relatively time consuming. These extreme bits cut through aluminium like butter but unfortunately the work piece wasn't securely clamped on the first one and not expecting the efficiency of this bit resulted in the boomerang shaped bracket rotating and nearly severing a delicate part of my anatomy. I made a formal complaint and was advised that I should have been wearing PPE (P? Protection Equipment) which I shall be wearing from now on!

Rated 5 out of 5 by from What a difference After spending far too much time attempting to drill into stainless steel with inferior quality bits I popped out in my frustration to Screwfix to buy this. What a difference quality makes, no pilot holes needed and no breakages. It cut through the steel with little effort.

Can I use this drill bit in a 10mm chuck or is there an alternative as I am limited to this size of chuck?

Asked by: Philip3
Hi Philip No you wont be able to use this drill bit in a 10mm chuck. The biggest metal drill bit you should use in a 10mm chuck is 10mm unless it is a specialist metal drill bit such as a step bit. If you go to the section for 'specialist drill bits and accessories' in power tool accessories you find some there.
