Review: Absolutely phenomenal value! - First of all, you're not getting professional quality Diamond hole saws for $8. That said, these work amazingly well! I cut out a small section of tile for my claw foot tub in about 30 seconds. Here's what you need to do to get nice round holes: 1. Have a small vessel of water to dip the saw into before you start and at intervals as you are drilling. Lay out (mark) your exact hole location with a full circle so you know exactly where to start. Start by tilting your drill at about a 5 degree angle and spin it FAST. Diamonds cut best at higher RPMs. Slow will work poorly and slowly... fast works much better because you aren't having to try to steady the drill as much. As you start cutting on your circle mark, slowly decrease the angle (square to the surface) so your drill begins making contact with the full circle as it cuts through. Once you've made full contact all the way around the circle, you can apply more pressure. Don't forget to cool the drill about every 15 seconds of drilling time by dipping it fully into the water. The water will fill the groove as you cut. It also acts as a lubricant to clear the dust and speeds cutting. Wetter is better! If you can dribble a steady flow as you drill, even better. I cut a 2in and also a 1in hole perfectly round with this set of hole saws. They work great. They arent prefect but they definitely do the job nicely. For the price, you can't beat these! I only needed a couple uses but these will cut many holes if used properly.
Review: Good value - Good variety and great value. Don't expect them to last as long as other more expensive bits, these are good for small jobs and they do it well enough. I had to drill a single hole in about 20 small ceramic pots and went through 6 bits in the process.

## Questions & Answers

**Q: Can I use this on stone like hard river rock?**
A: So far I have only used it on glass and clay/ceramic. I would strongly advise if you do try it, use water to help with the friction. It says that you can use it on stone , gemstones, rocks, and pebbles. Hopefully that answers your question

**Q: what is the chuck size 3/8 or 1/2 , I have 3/8 inch chuck?**
A: I have a dewalt drill with 3/8 in chuck its perfect.

**Q: What maximum thickness are these suitable for? What is the thickness of the diamond dust on the smallest three cutters?**
A: I can't tell you in exact dimensions how thick the coating of the cutters are. I can tell you that I cut a hole through a substantial hi-power electrical insulator big enough to run a 120-v plug through. Before using these bits-nothing could touch the ceramics it was made of. The secret to success is to run water on the project while drilling.

**Q: What machine can i buy for the drill bits?**
A: and drill will work, cordless or corded

### ⭐⭐⭐⭐ Works but poor quality
*by K***A on December 3, 2025*

They worked for my purpose, as i only need them once. If your going to need more than 4 holes, I would buy something else.
