Diamond Drill Bit - 6 mm Diameter - M14 Thread - For Porcelain Tile Granite Marble - 2 Pieces

Professional vacuum-brazed diamond drill bit designed for precise, low-vibration drilling in hard mineral surfaces such as porcelain tile, granite, and marble.
Enhanced durability: Vacuum brazing ensures stronger diamond retention versus electroplated alternatives, extending tool life under repeated use.
Reduced material damage: Optimized diamond height (10 mm) and geometry minimize chipping and cracking on brittle surfaces like ceramic and stone.
Thermal efficiency: Lower heat generation during dry or wet drilling improves operator safety and maintains hole accuracy.
Ready-to-use specification: Total length 60 mm, M14 threaded shank for secure chuck mounting — compatible with standard rotary hammers and angle grinders equipped with M14 adapters.This set includes 2 vacuum-brazed diamond drill bits engineered for demanding applications on dense, non-metallic materials. Each diamond drill bit features a 6 mm diameter, 60 mm total length, 10 mm diamond segment height, and M14 external thread. Suitable for both dry and wet drilling in porcelain tile, ceramic, granite, marble, and natural stone. The vacuum-brazing process delivers superior bond strength between the diamond layer and steel body, resulting in longer service life, reduced breakage, and cleaner holes. Ideal for professional tiling, renovation, and stonework tasks in residential or light commercial settings. Package contains: Diamond Drill Bit × 2.
