## Long description

Diamond hole saw for porcelain stoneware 50 mm from Keltin is a cutting accessory designed for clean, precise holes in hard tiles and ceramics. With a 50 mm cutting diameter and a 60-grit diamond segment, this hole saw is intended for drilling openings for plumbing fixtures, electrical fittings and other installation needs in bathrooms and kitchens. The tool uses an M14 threaded shank for direct mounting on angle grinders, providing a straightforward connection for fast setup and operation.
Advantages
The 60-grit diamond segment delivers efficient material removal while minimising chipping on porcelain stoneware surfaces. The 50 mm diameter allows for standard-sized openings often required for pipes and fittings. An M14 thread enables direct attachment to a range of angle grinders without additional adapters, reducing setup time. The design focuses on stability and consistent cutting performance when used with appropriate drilling technique and coolant.
Suitable for
Drilling clean, circular openings in porcelain stoneware (gres) and hard ceramic tiles
Preparing holes for plumbing fixtures such as pipes and taps
Creating openings for electrical boxes and conduit in tiled walls
Professional tiling and renovation work in bathrooms and kitchens
Key specifications
Cutting diameter: 50 mm
Abrasive: diamond segment, 60 grit
Thread type: M14 for direct attachment to angle grinders
Intended material: porcelain stoneware (gres) and hard ceramics
How to use
Mark the centre of the required hole on the tile. Fit the hole saw to an angle grinder with an M14 spindle, ensuring the tool is securely tightened. Begin drilling at low speed to establish a guide groove, then increase speed moderately while applying steady, even pressure. Use water as a coolant and lubricant throughout cutting to reduce heat and extend segment life; intermittent drilling with regular pauses can also help. After cutting, withdraw the tool slowly and inspect the hole for chipping; if necessary, smooth edges with a fine diamond file.
Usage recommendations
For best results, use with continuous water cooling and a steady, controlled drilling motion. Avoid excessive pressure and high speed to reduce wear on the diamond segment. Wear appropriate personal protective equipment, including eye protection, gloves and a dust mask, and secure the workpiece before drilling.
