Rated 5 out of 5 by from Great drill bit Bought 3 of these 5mm drill bits because I had to drill 44 holes in 5mm thick steel and thought they wouldn't last. I only needed to use 1 and it was still going strong - result

Rated 5 out of 5 by from Excellent buy I've bought these bits in different sizes before and can thoroughly recommend them. As the name suggests, they're multipurpose and will cur through most materials. They're sturdy and I've not yet had one break.

Rated 5 out of 5 by from A must have! A must have in your toolbox. I first purchased a set of these on offer (great value) but I find I use the 5.5 or 6 most regularly and as a result they are now wearing out. So, I ordered more, a 4, a 5 and a 6mm All good The click and collect service is as ever, very good.

any good for granite?

Asked by: trickytrees
Hi trickytrees, It will do granite, yes, but it is multiconstruction so not an ‘expert’ in that class, we suggest using a specific masonry rotary drill bit 41883 or ideally use an sds drill and bit 70234. Thanks for the question!

Will this work on porcelain tiles?

Asked by: Redun
Hi Redun, this bit is designed for all materials, for hard or brittle material we recommend making slow progress with a lubricant to prevent the tile from cracking around the drill site.
