Diamond Core Bit 12mm For Tiles

Extra Information

• Designed specifically for tile and stone — ceramic, porcelain (including grade 5), marble, slate and granite.
• Mandatory use of water (wet drilling) or coolant to prevent overheating of the diamond segments. No hammer or impact mode — rotary only.
• When starting a hole, begin at 45° angle on edge and then ease to vertical for best penetration and minimal damage.
• Check your drill’s rotations per minute (RPM) for 40 mm diameter bits to ensure safe, optimal cutting.

Features

• 12 mm diameter — ideal for larger through-holes in tile, stone or masonry.
• Premium diamond segment cutting edge — built to handle hard materials like marble, granite and porcelain.
• Lightweight body for easier handling.
• Fits standard drill chucks or compatible with tile/stone drilling rigs (check arbor thread).
• Water-coolable design recommended to prevent overheating and extend diamond life.

Benefits

• Efficient cutting: Diamond segments allow faster penetration through hard surfaces, saving time.
• Smoother holes: Produces clean edge holes in tile/stone, reducing chipping and rework.
• Versatile applications: From commissioning of plumbing and drainage in tiled walls to decorative stone installations, this bit handles them reliably.
• Durable build: The use of diamond-cutting edge and careful construction extends tool lifespan and lowers replacement cost.
• Better control: Designed for tile/stone applications to give you stability and precision in demanding conditions.

Safety

• Wear eye, ear and dust protection when drilling tile or stone surfaces.
• Secure the workpiece and ensure the drill is held firmly—rotating cores can catch and spin the tile if unsecured.
• Operate in rotary (non-hammer) mode only; hammer mode will damage the bit and the surface.
• Constantly supply water or coolant when drilling to prevent overheating of diamond segments and avoid failure.
• Inspect the diamond segments before and after use; if segments are chipped or missing, replace the bit to avoid unsafe operation.
