Review on 💎 Drilax300101 Porcelain Gemstone Necklaces and Bracelets: Exquisite Fashion Accessories by Doug Hook

Great. Better quality than most plated drill bits. MUST be lubricated and use a light touch, don't press too hard and loosen the hole to release the cut stone from the cut/cut The up and down motion works well and breaks easily to avoid back chipping A tiny tape mark placed on the bit at the correct height will tell you , as you approach. I recommend making an initial notch on stone/glass with a small diamond bit before drilling so the tip doesn't wander like you punch through a piece of metal before drilling. Remember this It doesn't drill through stone, but rather crushes and pulverizes stone or glass as it drills, unlike a wood drill, which removes wood chips from deep in the hole through the drill's flutes.
