Tork Craft Diamond Core Bit — 22 mm for Tiles

This 22 mm diameter diamond core bit from Tork Craft is built for precision hole-drilling through tough surfaces including ceramic tiles, grade-5 porcelain, marble, granite and slate. Featuring high-quality diamond segments that cut faster and cleaner than conventional bits, this core bit is a top-choice for plumbing, electrical, drainage or decorative penetrations in tiling and stone work. Usage with water / coolant is essential to maximise performance and lifespan.

The diamond core bit is used to drill holes in:

Ceramic tiles
Marble
Grade 5 porcelain (hardest)
Granite
Glass
Slate

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.

An indication of the correct spindle speed:

DIAMOND CORE BIT DIAMETER	SPINDLE SPEED
Ø5.0mm	800 rpm
Ø6.0mm	600 rpm
Ø7.0mm	500 rpm
Ø8.0mm	500 rpm
Ø10.0mm	400 rpm
More than Ø10.0mm (>10.0mm)	less than 400 rpm

Pro Tip

Use a small amount of water or a wet sponge at the drill point to keep the bit cool and reduce tile glazing blow-out. Start at a low rpm and increase only when stable.

Features

22 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.
