## 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

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    good quality
  

*by J***N on Reviewed in the United Kingdom on 14 October 2023*

Great quality cut through Yorkshire stone no problem.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    An excellent tool for drilling porcelain
  

*by P***L on Reviewed in the United Kingdom on 22 September 2022*

The drill was bought specially to drill holes in 20mm thick porcelain tiles which it did quite easily. It has no centre drill to help line with alignment, so I made a jig i.e. a piece of 5mm thick wood with a 50mm hole in it and clamped it in the position of the hole. I was told it would only last for the 5 holes I drilled but it is still in excellent condition.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Great value
  

*by A***R on Reviewed in the United Kingdom 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!
