## Long description

Diamond core drill bit for porcelain gres 12 mm with M14 thread by Keltin is designed for creating precise round holes in hard ceramic and porcelain gres tiles. With a 12 mm cutting diameter and an M14 threaded shank, the bit is intended for wet drilling to reduce heat and extend tool life. It is suitable for use with angle grinders or drills equipped with M14 adapters and is supplied in bulk packs as specified by the manufacturer.
Advantages
The diamond-segment cutting edge ensures efficient material removal and maintains hole geometry in dense porcelain gres. Wet drilling capability minimizes dust and prevents overheating, resulting in longer service life for both the drill bit and the tool. The M14 threaded shank offers secure attachment to compatible angle grinders and adapters, providing stable operation and consistent results. The 12 mm diameter is a common size for plumbing and electrical installations, enabling accurate and repeatable hole placement.
Suitable for
Drilling precise holes for plumbing fixtures through porcelain gres and ceramic tiles

Tiling and renovation projects requiring clean round holes in hard tiles
Key specifications
Cutting diameter: 12 mm
Shank type: M14 threaded shank
Intended use: Wet drilling in porcelain gres and hard ceramic tiles
Suitable tool types: Angle grinders or drills with M14 adapter
Cutting edge: Diamond segments for hard material performance
How to use
Secure the drill bit to an angle grinder or to a drill with an appropriate M14 adapter. Prepare the workpiece and ensure a steady supply of water to the drilling area to keep the cutting edge cool and to reduce dust. Start drilling at low speed to establish the initial position, then apply steady, moderate pressure while maintaining cooling. Withdraw periodically to clear slurry and inspect the progress. After completing the hole, clean and dry the bit before storage.
Usage recommendations
Use personal protective equipment, including eye protection and gloves, and ensure stable support for tiles during drilling. Maintain continuous water flow for effective cooling, and avoid excessive lateral force to prevent damage to the tile and the bit. Replace the bit when cutting performance noticeably decreases.
