SHDIATOOL Diamond Core Drill Bits 6mm 2-Pack – Vacuum Brazed Hole Saw for Porcelain Tile, Marble, Brick

Meet the SHDIATOOL Diamond Core Drill Bits 6 mm two-pack, built to elevate tile and stone projects with reliable precision. The cutting edge measures 6 mm in diameter (approximately 1/4 inch), paired with a 5/8-11 threaded connection that fits many common angle grinders. Crafted with vacuum brazed technology and a 10 mm diamond segment, these bits are designed for steady contact and enduring edge performance while you work through porcelain, ceramic tile, marble, or brick. An internal cooling wax helps manage heat during drilling, supporting smoother operation and longer life for the cutting edge. A note on compatibility: to fit these hole saws on some drills or machines, you may need an adapter (SDS, Hex, or Round Plus Shank).
