Diamond Hole Saw for Porcelain Gres 38 mm with M14 Shank, Keltin

The Keltin diamond hole saw for porcelain gres 38 mm with M14 shank is a specialty cutting tool designed to drill clean, precise circular holes in hard ceramic and porcelain gres tiles. Intended for use with angle grinders and other compatible power tools that accept an M14 threaded connection, this hole saw provides a focused diamond cutting edge that reduces chipping and produces smooth hole walls suitable for pipe penetrations, fixture mounts and electrical fittings.

Advantages

The diamond segment rim delivers efficient material removal and extended working life on dense porcelain gres. The 38 mm diameter gives a commonly required size for many plumbing and electrical penetrations while the M14 shank ensures secure attachment to standard angle grinders. Designed to minimize chipping and to create burr-free edges, the tool helps achieve consistent, repeatable holes in hard tiles when used with appropriate cooling and steady feed.

Suitable for

• Drilling holes for plumbing pipes and conduits in porcelain gres tiles
• Cutting openings for fixtures such as faucets, valves and mounting hardware
• Creating holes for electrical boxes, cable glands and conduit entries
• Work on bathroom, kitchen and commercial tiling where neat circular openings are required

Key specifications

• Cutting diameter: 38 mm
• Connection type: M14 threaded shank suitable for compatible angle grinders and adapters
• Segmentation: diamond-rimmed cutting edge for hard ceramic and porcelain gres
• Recommended application: dry or wet drilling with appropriate cooling to extend tool life
• Suitable materials: porcelain gres, hard ceramics and similar dense tile materials

How to use

Mark the center of the desired hole on the tile and use a pilot guide or template if available to maintain position. Secure the tile and start drilling at low speed to establish the cut, then apply steady, moderate pressure while maintaining rotation speed appropriate for the tool and machine. For best results use water cooling or periodic pausing to prevent overheating; avoid excessive force which can cause cracking. If using an angle grinder, ensure the M14 shank is properly tightened and follow the grinder manufacturer's safety instructions, including eye, ear and hand protection.

Usage recommendations

Use water or a coolant spray where possible to reduce heat and prolong diamond segment life. Begin with a light touch to establish the cutting path, and progress with steady pressure. For thin tiles, support the workpiece from underneath to prevent breakout. Inspect the cutting edge before use and replace the hole saw when cutting performance declines or segments are worn.
