## Summary description

Diamond core bit AWTools KORONA M14 with a 14 mm diameter and M14 thread (model AW47284). Designed for drilling small-diameter holes in hard materials such as ceramic, porcelain, glass and tiles. Suitable for use with M14-threaded rotary tools or drill adapters, it provides precise hole cutting for installations, plumbing, electrical and finishing work.

## Long description

The AWTools KORONA diamond core bit with M14 thread and a 14 mm cutting diameter is intended for drilling small, accurate holes in hard brittle materials. It is suitable for ceramic, porcelain, glass and various types of wall and floor tiles. The tool is built to be mounted on M14-threaded rotary tools or on standard drill adapters, offering stable engagement and controlled rotation for precise hole formation during installations, plumbing and electrical routing.
Advantages
The diamond-segment cutting edge provides increased wear resistance and consistent cutting performance when working with glazed and unglazed tile surfaces. The M14 thread ensures a secure connection to angle grinders and rotary tools, reducing slippage and vibration. Its compact 14 mm diameter enables precise small-diameter hole making without unnecessary material removal, which helps preserve surrounding tile integrity and finish.
Suitable for
Drilling holes in ceramic and porcelain tiles
Creating openings in glass and glazed surfaces
Plumbing and fixture installations requiring small-diameter passages
Electrical conduit and cable entry points in tiled walls
Finishing work where clean, precise holes are required
Key specifications
Cutting diameter: 14 mm
Thread type: M14
Cutting material: diamond segment edge
Intended materials: ceramic, porcelain, glass, tiles
Tool compatibility: M14-threaded rotary tools and adapters
How to use
Secure the diamond core bit in a compatible tool with M14 fitting or an appropriate adapter. Mark the drilling point on the tile and, when possible, start drilling at low speed to establish the position. Apply steady, moderate pressure and maintain consistent rotation; do not force the bit. Use water as a coolant and lubricant to reduce heat build-up and prolong cutting life, keeping the drilling area supplied with a steady flow or periodic wetting. Once the hole is complete, withdraw the bit slowly while the tool is still rotating to reduce chipping.
Usage recommendations
Use low to medium rotational speed with steady pressure and continuous cooling when drilling hard glazed surfaces. For best results, stabilize the workpiece and protect adjacent tiles with masking to prevent accidental damage.
