New 50 pcs diamond coated rotary burr box set. There are many shapes such as sphere, cylinder, bullet, needle, etc..... 1/8" (3mm) shank for use with rotary tools, drills, high speed die grinders, and flex shafts. Fit dremel rotary machine, Foredom Grobet etc. Great quality material. Suitable for use in grinding of glass, marble, rock or jewellery.

These are great burrs with some interesting effects possible due to the large size heads. This allows for some unusual surface treatments. Remember that when using wide heads you will need to reduce the speed of your tool. Also use plenty of lubricant/coolant with these if you want them to last a long time.
