Rated 5 out of 5 by from The best to get These drill bits are always the best most reliable to get. They don't overheat as standard bits will in a short space of time, then snap. They stay sharp so make short work of drilling into metal.

Rated 5 out of 5 by from Impressed Slightly mistrust drill bits with anything other than a conventional cut head, but have to say I was very impressed how easy it was to drill 12mm holes through rsj (cut 8mm then 12mm with cordless drill) . Impossible to resharpen when blunt but seems to stay sharp for a good few holes

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.

This 13mm drill - Is it a plain shank bit to fit 12mm chuck

Asked by: Joe942
Hi Joe This drill bit has a non slip shank with 3 flat part to eliminate slipping in the chuck. I couldn't say 100% if it would fit into a 12mm chuck as we have never done this sized chuck, our chucks are either 10mm or 13mm. As a general rule the chuck size denotes the maximum sized metal drill bit that it would fit, so a 13mm metal drill bit should be the max being used by a 13mm chuck. I hope that helps you?

Drill Bit

Hi I have a DeWalt drill and need a drill bit to drill through a steel lintel. Can you recommend one please? Thx
Asked by: TheLady
Hi There The DEWALT Extreme 2 series are going to be one of the toughest drill bits for drilling metal, so if you are looking for a 6mm bit then this one would be great.
