Rated 5 out of 5 by from Great Product Great product, much better than other drill bits I've used. Was a little sceptical as had to drill into steel walkway support, but once started it had no problem eating it's way through. Will definitely be buying & using other bit sizes & saving on frustrating endless drilling.

Rated 5 out of 5 by from Tough drill bit Having destroyed 4 standard black and decker HSS drill bits trying to get through a 5mm steel bar I decided to invest in the correct bit of kit for the job. This bit totally sailed through the steel no problems at all! For tough jobs this is highly recommended.

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.
