## Summary description

Keltin diamond core bit for porcelain gres, 30 mm cutting diameter with M14 thread. Designed for drilling clean holes in dense ceramic and porcelain tiles; suitable for use with angle grinders or drills equipped with M14 arbor. Provides efficient material removal and long wear life for tile installation, plumbing, electrical pass-throughs and fixture mounting.

## Long description

Keltin diamond core bit for porcelain gres, 30 mm cutting diameter with M14 thread is a specialist drilling tool engineered for precise hole cutting in dense ceramic and porcelain tiles. It is intended for use with angle grinders or drills that accept an M14 arbor and is optimized to deliver clean, circular holes with minimal chipping. The construction combines a solid steel body and a diamond-segment cutting crown to provide durable performance when installing fixtures, routing plumbing lines or creating electrical pass-throughs in tiled surfaces.
Advantages
The diamond cutting crown ensures efficient material removal from hard porcelain gres while reducing the risk of cracking around the hole edge. The 30 mm diameter offers a common size for many plumbing and mounting needs without excessive material waste. Compatibility with M14 arbors enables direct mounting on many grinders and rotary tools for stable drilling. The design balances cutting speed and wear resistance, resulting in extended tool life compared with non-diamond alternatives.
Suitable for
 Drilling through dense porcelain gres and ceramic tiles
 Creating holes for plumbing fittings and pipe passages
 Making clean openings for electrical outlets or cable routing
 Preparing mounting points for fixtures and bathroom accessories
Key specifications
 Cutting diameter: 30 mm
 Shank/thread type: M14
 Cutting material: diamond segments
 Body material: steel construction with welded crown
 Intended workpiece: porcelain gres and dense ceramic tiles
How to use
Mount the diamond core bit securely on an appropriate tool with an M14 arbor. When drilling porcelain gres, use steady, even pressure and avoid applying excessive force to reduce the risk of cracking. For best results, drill at low to moderate speed and keep the workpiece supported and stable. Intermittent drilling with cooling—by using water or allowing brief pauses—will prolong diamond life and reduce heat buildup. After completing the hole, remove any debris and check the opening for smoothness before installing fittings.
Usage recommendations
For longest service life, use water cooling or periodic pauses to dissipate heat, secure the tile to prevent movement, and start with a small pilot contact before full engagement to minimize chipping. Always wear appropriate eye, hand and respiratory protection when cutting tiles.
