KATUR 40mm Dia Diamond Hole Saw Diamond Core Drill Bit, Masonry Hole Saw Porcelain Tile Hole Cutter for Marble, Glass, Slate, Ceramic, Granite, Quartz Gemstone : desertcart.co.uk: DIY & Tools

Review: Great drill bit worked for us - Arrived quickly, in handy little plastic tub. At first hubby was concerned because there was no centre drill bit, and he was worried about the kick back and also the accuracy aspect. We stuck with it, because of the 2 year warrantee. Taking the attitude that if it was no good, we could send it back. Wanted to drill holes through concrete, slabs. IT WORKS. I have posted a video and some pictures, and can confirm, this product does exactly as claimed. I now have one very happy hubby, and 3 holes, drilled. I would like to add, that depending on the material, your drilling, you may want to consider the motor power of the drill. Also for added pressure and stability, a drill with a handle is a good option. We used to drill through 50mm thick paving slab.
Review: Gets through lots of hard materials - Used to bore a hole through 12mm thick ceramic tile, then the tile cement behind that, then the breeze-block wall behind that. No sign of wear on the cutting edges even after ploughing through all that. The hole size was accurate, it had a nice smooth bore, and a piece of 40mm diameter plastic tubing slid into the hole perfectly. Since then used it on other types of tiles. It's holding up well. Keeping it cool is the trick. Drill for a minute or two then dunk it a cup of water to cool. Repeat until it gets through.

## Questions & Answers

**Q: What size pilot drill is required?**
A: You actually do if you want a good positioned hole as the cutters can slip even with tape underneath.
I started with masking tape over the area in question then pilot drilled with a 4mm masonry bit, then a 10mm bit. 
After that I work my way through the diamond cutters up to the 18mm and ended up with a carefully drilled hole on the precise point.
Just a ‘better safe than sorry’ approach which worked perfectly for me...a seasoned DIYer.
Great value for the money! Even if I never use them again...definitely worth it to cut out the two shower pipe holes in my 600x300x10mm ceramic bathroom tiles for my bathroom project.

**Q: Is this diamond bit suitable to drill A hole though a 19mm thick piece of glass**
A: It’s more than capable of drilling a hole in 19mm glass

**Q: I need to drill 30mm holes in 6 London house bricks to fit lights..... will this make it through 1 let alone all 6?**
A: It should do, it got through 20mm porcelain. I imagine that'll be much harder than a London brick

**Q: will this cut into aluminium?**
A: I cut thick floor tiles and had no trouble just cut slowly with adding water and I don’t think it would struggle just make sure you keep it cool with spraying water on it

### ⭐⭐⭐⭐ Great value
*by A***R on 18 October 2022*

I needed to cut just 2 holes in some tiles and was reluctant to pay over £40 for a branded holesaw, when I wouldn't use it a lot. I decided to try a cheap one, as I could always return it, if it didn't manage just 2 holes. This holesaw managed to cut a plywood template (highly recommended) and the required 2 holes through, admittedly thin, tiles. I would guess that it still has life in it too. Definitely recommended, if you don't need much use out of it!
