Review: Good enough, for the money. - Good enough, for the money. There's some reviews saying that they're only good for one hole - Well I've used one for two holes (I mucked up the first one, my fault) in ceramic tiles, and I reckon it would go again. Recommend making a jig/guide with a bit of timber with a hole in it the same size as the hole saw, to help guide it in. These are DIY grade tools, which is fine for the price - I bought the whole set for much less than one of the saws would have cost from Bunnings, and I do only need them to work a couple of times; I'm only renovating one bathroom. Realise that you do get what you pay for, but if you only need to make a few holes, then these are the go!

## Questions & Answers

**Q: Doesit have a pilot? What type of pilot do you need for glass?**
A: If you make a hole the aize you are trying to make in a small plank of wood first, tou can then clamp the wood plank to the glass or ceramic you intend to cut a hole into and the wood plank will act as a guide/stabiliser.  This is how I have always made precise, no wobble cuts when challenged with using a hole saw without a pilot bit in the center.  Although, I do have many piloted wood hole saws that I can use to create the guide plank, so that helps.  

Hopefully this makes sense amd you understand the method I have explained.

**Q: Is there an available guide for this tool?**
A: Not that I know of, I found cutting thru brick I had to take it slow. I just tipped the cutting tool slightly till I had started a slight half circle then was able to hold to start the full circle. I was very surprised that it did a nice job cutting thru the brick half at a time

**Q: How long do they last? Or how often can you use them**
A: I bought the set for two particular diameters that I needed.  I have used those to drill holes several times and they worked well. They are ideal for someone like me who needs to make several holes in tiles while renovating a bathroom. I don’t believe that they were ever intended for professional use or any use where they would be drilling many holes per day on a regular basis.

**Q: Can this cut through a mirror?**
A: Yes, this drill bit can cut through a mirror
