## Questions & Answers

**Q: Do these have 1/4” shank?**
A: These are meant to fit dremel style tools so 1/8”, but they are not worth the money. Get a true burr style and not in spherical form.

**Q: Can I grind glass with these bits(especially on places that my Glassgrinder can't reach)**
A: Yes..all I use them for is glass etching..I use a dremel tool

**Q: Will these work on clay pots?**
A: don't see why not. They are tuff enough for glass ceramic shouldn't be a problem. 
It depends on what you want to do on the pots you might try these also:

**Q: can these be used on the dremel stylo+?**
A: Yes but they’re very poor quality. The balls quit engraving/etching after only a few passes. Look for a traditional diamond coated burr bit

## Customer Reviews

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Great price, good quality.
  

*by S***3 on Reviewed in the United States on November 9, 2011*

I use these to carve stone with a dremel tool.  For the price, they have proven to be the most cost effective tools.  The different sizes allow fine detail and they hold up well under this harsh use.  At this price, I can afford to buy a couple of sets and not worry about them wearing out after a couple of pieces of work.  The stone is very hard on the bits, but typically one bit will last me all the way through a piece of work, which was rare with the tile bits I could buy at the 'Depot' locally.  I was very pleased to find these sets on Amazon at a wonderful price.

    these little diamond tipped jewels made me look like a pro
  

*by D***N on Reviewed in the United States on January 31, 2015*

My boyfriend bought me a Dremel kit for Christmas and I thought I would try my hand at etching a plate. I prepped the plate and put the bit I wanted into the dremel attachment and etched away. I have never etched before using any method so, I was unsure how this was going to turn out but, these little diamond tipped jewels made me look like a pro. They were inexpensive but definitely high quality. Very durable and did exactly as they were or, at least as, I had intended.  My plate turned out beautiful thanks to these bits. I can't wait to use them again. They are a great product for the price.

    Good variety pack for diamond ball burrs.
  

*by M***O on Reviewed in the United States on June 4, 2019*

Seemed to be well bonded diamond. So far so good. The shanks were not tapered up by the ball quite as long (gradual) as I had wished but they are working. Thank you. I wish they sold a coarser set, too.
