## Long description

The Diamond Core Bit for Porcelain Gres Keltin 18 mm M14, 100 mm is a specialized cutting tool designed to drill precise holes in hard ceramic and porcelain gres. With an 18 mm cutting diameter and 100 mm overall length, this core bit fits angle grinders and rotary tools that accept M14-threaded accessories. It is intended for installers and tradespeople who need accurate circular cuts for plumbing, electrical fixtures and fittings in dense, glazed tiles.
Advantages
This diamond core bit combines a reinforced shank with an abrasion-resistant diamond cutting edge to maintain cutting performance on hard surfaces. The M14 thread connection ensures secure mounting in common angle grinders and compatible rotary tools, reducing wobble and improving hole quality. Its 100 mm length provides sufficient reach through tile and thin backing materials while the 18 mm diameter gives consistent, clean holes suitable for standard pipe and fixture sizes.

Drilling holes for plumbing and pipe penetrations through porcelain gres and ceramic tiles
Making openings for electrical boxes, conduits and cable glands in tiled surfaces
Creating precise holes for sanitary fixtures, fittings and anchors in dense tiles
Key specifications
Cutting diameter: 18 mm
Thread connection: M14
Overall length: 100 mm
Cutting material: diamond segment suitable for hard glazed tiles and porcelain gres
Tool compatibility: angle grinders and rotary tools accepting M14 accessories
How to use
Select appropriate personal protective equipment, including safety goggles, gloves and a dust mask. Secure the workpiece and mark the drilling position. Fit the core bit to a compatible M14 spindle tool, ensuring it is tightened according to the tool manufacturer's instructions. Begin drilling at low speed to establish the cutting edge, then apply steady, moderate pressure and maintain a consistent speed. For best results on porcelain gres, use intermittent drilling with light cooling (water spray or controlled wetting) where the tool and bit permit. Withdraw the bit periodically to clear debris and avoid overheating.
Usage recommendations
Use light to moderate pressure and avoid excessive side loading. When possible, use water cooling or frequent pauses to prolong bit life and reduce dust. Match the 18 mm diameter to the pipe or fitting size required and verify tool compatibility with the M14 thread before starting work.
