## Summary description

Keltin diamond core drill bit for porcelain gres, 16 mm diameter with M14 threaded shank.

## Long description

The Keltin Diamond Core Drill Bit for Porcelain Gres 16 mm with an M14 shank is a purpose-built tool for creating precise holes in hard ceramic and porcelain gres tiles. Designed for use with angle grinders and other rotary tools that accept an M14 threaded spindle, this core bit features a diamond-segment cutting edge that maintains accuracy when working with dense, glazed surfaces. It supports both wet and dry drilling methods depending on the tool, cooling arrangement and technique applied, and is commonly used where clean, round openings are required for plumbing, electrical fixtures, anchors or pipe passages.
Advantages
The diamond cutting edge provides efficient material removal and extended life on hard tiles while preserving hole geometry. The M14 threaded shank ensures secure mounting in angle grinders and compatible adapters, reducing wobble and improving control. The 16 mm diameter is suitable for many standard plumbing and electrical penetrations, and the design tolerates both wet drilling for cooling and dust suppression as well as careful dry drilling where appropriate. Overall, the bit delivers repeatable, accurate holes in porcelain gres with reduced chipping when used with correct feed rate and support.
Suitable for
Drilling holes for plumbing pipes and fittings in porcelain gres and ceramic tiles
Creating openings for electrical boxes, conduit and cable pass-throughs
Making precise round cutouts for fixtures, anchors and mounting hardware
Working with angle grinders or rotary tools equipped with M14 threads
Key specifications
Cutting diameter: 16 mm
Shank type: M14 threaded shank for angle grinders and compatible spindles
Cutting edge: diamond-segment for hard ceramic and porcelain gres
Drilling modes: suitable for wet drilling; dry drilling possible with appropriate technique and tool
Intended material: porcelain gres, hard ceramic tiles and similar dense glazed surfaces
How to use
Secure the M14 shank firmly in the angle grinder or adapter according to the tool manufacturer’s instructions. Position the drill bit perpendicular to the tile surface and start at low speed to establish a steady contact point; use light, consistent pressure and avoid forcing the bit. For wet drilling, supply a steady flow of water to the cutting area to cool the diamond segments and reduce dust. For dry drilling, work in short intervals to prevent overheating, withdraw periodically to clear debris and allow cooling. Support the tile from behind when possible and protect adjacent surfaces to reduce chipping.
Usage recommendations
Use appropriate personal protective equipment (safety glasses, gloves, dust mask) and follow the angle grinder or rotary tool safety guidelines. For best results on porcelain gres, prefer wet drilling when the tool and job conditions allow; maintain steady speed and gentle feed to extend bit life and ensure clean hole edges.
