Diamond Hole Saw for Porcelain Gres 8 mm M14 Keltin

Diamond Hole Saw for Porcelain Gres 8 mm M14 Keltin is a dry and wet-compatible cutting accessory engineered for precise hole drilling in hard ceramic and porcelain gres. The tool features an 8 mm cutting diameter and M14 thread for secure mounting on angle grinders and rotary tools with M14 fittings. It is intended for producing clean, accurate holes for fittings, pipes and fixtures in tile and other dense surfaces when used with appropriate cooling and controlled feed.

Advantages

The diamond cutting edge provides enhanced wear resistance and consistent performance on dense ceramic and porcelain gres. The M14 threaded shank ensures firm attachment to compatible power tools, reducing wobble and improving hole accuracy. The compact 8 mm diameter is suited to creating small-diameter penetrations while preserving surrounding material integrity when used with correct technique and cooling.

Suitable for

• Drilling holes for plumbing fittings and pipes through porcelain gres and ceramic tile
• Creating fixture and anchor points in dense tile surfaces
• Small-diameter penetrations where clean edges and minimal chipping are required

Key specifications

• Cutting diameter: 8 mm
• Thread type: M14 compatible
• Cutting material: diamond grit cutting edge
• Intended materials: porcelain gres, ceramic tile and similarly hard surfaces
• Mounting: designed for angle grinders and rotary tools accepting M14 fittings

How to use

Mount the hole saw on a compatible tool with M14 thread and secure it firmly according to the tool manufacturer’s instructions. Begin drilling at low speed to establish the hole position, applying steady, moderate feed pressure. For best results on porcelain gres, use intermittent cooling with water to reduce heat and extend cutting life; avoid excessive pressure and high RPM that can cause overheating or premature wear. Withdraw periodically to clear slurry and inspect the cutting edge.

Usage recommendations

Use personal protective equipment (safety glasses, gloves, dust mask) and ensure the workpiece is firmly supported. For extended tool life and improved hole quality on porcelain gres, apply light water cooling and operate at controlled speed; replace the hole saw if diamond wear reduces cutting performance.
