These are very effective in drilling into aluminium. I don't know how they perform on other material but I think they will be just as good.
Wouldn't purchase any other drill bit great quality
Great set of drills. Good to centre and accurate when drilling.
These are the Swiss Army Knife of drill bits - claim to do lots of things and none of them well. OK for drilling into brickwork, wood and plasterboard. Easily blunted by blockwork, and concrete and ineffective on metal. Overpriced, underspecified and overrated. Can't recommend and would not buy again.
Excellent set of drill bits, just what I needed to replace my old set.
Excellent set drills though walls like butter highly recommended.
Exactly what I needed to add to my toolbag. No slippage or stoppage - these drill bits cut through brickwork/masonry like a knife through butter. Great buy for trades who need this extra durability.
Great product but why have two bits the same size?
These are my go to drills to keep in the toolbar. They seem to stay sharp for ages!
Excellent drill set great value from a well stocked company
Love how these drill through both wood and blocks. Even put a clean hole in hard pvc
I wanted a good set of masonary drill bits as all my old ones were blunt. These are amazing, drilling into brick with the 7mm bit was extremely easy. The best I have ever had.
They are ok if you use water for cooling same as wet tile drills, I used the 5.5 mm & 6 mm with water but the first bit I used the 5mm overheated without coolant despite running on lowest speed, so it depends on the type of tiles & their thickness & how much force you apply to get the best out of these they will drill into brick & masonry on problem
poor, already gone rubbish and I'm only a home user. I have put up two solar lights and one shelf into tiles. The drill bits worked fine but any masonry and they are now going blunt.
