The Diamond Needle Head Grind Burrs are ultra-fine tools designed for micro-engraving, precision drilling, and intricate detailing on hard, brittle materials like glass, ceramics, gemstones, PCB substrates, and hardened alloys. Featuring a needle-like tip with galvanically bonded diamond grit, these burrs excel in high-precision workflows requiring sub-millimeter accuracy.
Key Features
