QWORK® 8 Pcs Multi Material Drill Bit Set 3, 4, 5, 6, 8, 10, 14, 16 mm for Tile,Concrete, Brick, Glass, Plastic and Wood Tungsten Carbide Tip

Used the 8mm, 10mm and 12mm drill bits in Ceramic wall tiles and we have nearly perfect holes. There is very slight chipping to the glaze around the hole but this will be covered anyway. Had to drill 18 holes in total so not terribly high usage but they certainly did not break straight away. Used in an old ish 18v Dewalt

Did the job drilling wall tiles so I'm happy

Good product and delivery service, quite effective but wears off after about drilling 3 cm holes

Does exactly what it says on the tin 👍

I cannot believe the difference in these to my old drill pieces. It took several minutes to drill a hole a couple of cms deep through brick with my old drill pieces and I almost gave up bothering as it didn't feel like it was going futher then decided to buy these and within 20 seconds they drilled an inch deep hole in the brick. It went through the brick like butter. These are one of my best purchases on amazon. I'm looking fowards to more drilling jobs using these as it's so easy and quick. I knew these would be better but the difference is night and day. I've only used them once using the smallest drill piece so hopefully they will continue to impress.

They’ve done the job absolutely brilliantly. Thank you

No even worth one star stay away, broke on first hole,

Drilled very well into concrete slabs, minimal effort required, BUT, they only lasted for 3 holes, the tops snapped off. So if you have more than 3 holes to drill... I'd recommend something else
