Review on ๐Ÿ”ฎ High Precision PHYHOO 11pc Ball Sphere Diamond Burr Polishing Grinding Bits: Achieve Superior 0.6mm to 6mm Results by Mike Castro

Revainrating 5 out of 5

Cut Hard Rock (if you know what you're doing)!

This set was used to drill a 4mm diameter hole in a hard emerald stone. I drilled underwater to keep the bit and rock cool, which worked beautifully. I now have a unique opaque emerald pendant on my necklace. Works in my Dremel 3000 + Dremel Jacob's Chuck attachment. Thanks for the great price and quality product!

Pros
  • 11 ball sizes from 0.6 mm to 6.0 mm; 2.35mm diameter rods
Cons
  • None
