Diamond hole saw for porcelain tile 32 mm M14 Keltin

Diamond hole saw 32 mm with M14 thread by Keltin is a drilling accessory engineered for making precise circular holes in porcelain tiles (gres) and other hard ceramic surfaces. The tool has a continuous diamond-segment cutting edge that provides high wear resistance and smooth cutting performance during wet drilling. Designed for use with angle grinders or rotary tools equipped with an M14 arbor, this hole saw is intended to produce clean openings for installations where accuracy and edge quality matter.

Advantages

The diamond cutting edge maintains sharpness longer than conventional abrasives, reducing chipping and minimizing the need for finishing. Wet drilling capability controls heat and dust, extending tool life and improving hole quality. The 32 mm diameter offers a common size for plumbing and electrical fixture penetrations while the M14 thread ensures secure attachment to compatible grinders and rotary tools. The segment design aids debris removal and consistent cutting speed.

Suitable for

• Drilling precise holes in porcelain tile (gres)
• Creating openings for faucets, pipes and fixtures in tiled surfaces
• Wet drilling of ceramic and similar hard materials
• Use with angle grinders or rotary tools with M14 arbor

Key specifications

• Cutting diameter: 32 mm
• Cutting material: diamond segments for high wear resistance
• Mount type: M14 threaded arbor
• Recommended drilling method: wet drilling to control heat and dust
• Typical applications: porcelain tile, ceramic and similar hard materials

How to use

Secure the hole saw to an angle grinder or rotary tool with an M14 arbor following the tool manufacturer's mounting instructions. Mark the drilling position on the tile and begin drilling at low speed to establish the pilot contact, keeping the tool steady and perpendicular to the surface. Apply light, consistent pressure while introducing water to the cutting area to cool the diamond segments and remove slurry. Increase speed gradually as the cut progresses, maintaining continuous water flow to avoid overheating and to reduce dust.

Usage recommendations

Use personal protective equipment including eye protection and gloves. Ensure the workpiece is supported and immobilized. Avoid dry drilling on porcelain tile to prevent damage to the tool and the material. If chipping occurs at the edge, back the tool out, clear debris and resume with reduced pressure and more cooling water.
