Review on Glastar Diamond Drill Bit Crafting by Angie Johnson

Based on our own experience this diamond drill bit is a total game-changer for stained glass making .It easily and smoothly drills through glass without cracking or chipping. It saves time and effort and lets us create INTRICATE designs and shapes with ease. The only downside is that the bit can become dull over time and needs replacement. But overall, this is a must-have tool for any stained glass artist..
