Diamond core hole saw Smart 45 mm M14 for porcelain stoneware

Diamond core hole saw Smart 45 mm M14 for porcelain stoneware is a specialized cutting tool designed to create precise circular openings in hard tile materials such as porcelain stoneware (gres). Engineered for use with angle grinders and rotary tools that accept an M14 arbor, the core bit features a 45 mm cutting diameter ideal for plumbing, electrical, and installation tasks where a clean, accurate hole is required without fracturing surrounding tiles.

Advantages

The diamond-segmented cutting edge ensures efficient material removal and long life when cutting dense, vitrified tiles. Its 45 mm diameter provides a standardized size for many pipe and fixture penetrations, while the M14 thread offers secure attachment to common angle grinders. The construction minimizes chipping and reduces the need for extensive finishing around the hole, producing consistently round openings with minimal effort.

Suitable for

• Creating holes for plumbing pipes and fittings in porcelain tiles
• Installing electrical boxes, conduits, and cable pass-throughs in tiled walls
• Cutting openings for ventilation or fixtures in bathroom and kitchen tiling

Key specifications

• Cutting diameter: 45 mm
• Mount type: M14 threaded arbor compatibility
• Material compatibility: porcelain stoneware (gres), vitrified and hard ceramic tiles
• Cutting edge: diamond-segmented rim for hard, abrasive surfaces
• Intended tool: angle grinders and rotary tools with M14 mounting

How to use

Secure the diamond core hole saw to an angle grinder or compatible rotary tool using the M14 thread according to the tool manufacturer’s instructions. Mark the center of the desired hole on the tile, support the tile or workpiece to prevent movement, and start the tool at low speed to establish the cut. Apply steady, even pressure and maintain a perpendicular angle to the surface; for best results, periodically cool the cutting area with water to reduce heat and prolong tool life. Complete the cut by gradually increasing speed and allowing the diamond segments to wear in evenly.

Usage recommendations

Use appropriate personal protective equipment (safety goggles, gloves, dust mask) and clamp or support tiles securely. For through-cuts in wall-mounted tiles, protect the underlying surface and proceed slowly near the finish side to avoid chipping. Intermittent cooling with water is recommended when cutting porcelain stoneware to control dust and heat, and to extend cutting performance.
