8 mm diamond core drill bit by Expert+ with an M14 threaded shank and maximum rated speed of 12,000 rpm.

## Long description

Diamond Core Drill Bit 8 mm from Expert+ is a specialist cutting and drilling accessory with an M14 threaded shank designed for precision work in hard materials. The bit is intended for use with angle grinders and rotary tools that accept M14 fittings and is rated for a maximum rotational speed of 12,000 rpm. Its diamond cutting edge allows controlled removal of material in ceramic, tile, glass and natural or engineered stone, while the construction supports both wet and dry drilling depending on the substrate and manufacturer guidance.
Advantages
The diamond cutting segment provides high abrasion resistance and consistent cutting performance when drilling hard, brittle surfaces. The M14 shank ensures secure attachment to compatible angle grinders and many rotary tools, reducing wobble and improving control. A maximum speed rating of 12,000 rpm gives a wide operational range for different tools, and the ability to operate wet or dry adds versatility for installers and repair technicians working with varied materials and site conditions.
Suitable for
Drilling precise holes in ceramic tiles and porcelain
Cutting openings in glass and glazed surfaces with appropriate technique
Creating holes in natural stone and engineered stone countertops
Installing fixtures where clean, small-diameter holes are required
Key specifications
Cutting diameter: 8 mm
Shank type: M14 threaded shank for angle grinders and M14-capable tools
Maximum rotational speed: 12,000 rpm
Suitable operation modes: wet drilling and dry drilling (use mode according to material and tool guidelines)
Primary applications: ceramic, tile, glass and stone
How to use
Secure the drill bit into the tool’s M14 fitting according to the tool manufacturer’s instructions, ensuring a tight and stable connection. For tile and ceramic, begin at low speed to establish a starter point and apply steady, even pressure while keeping the tool as perpendicular to the work surface as possible. When drilling glass or delicate stone, consider using a backing support and slower speed to reduce vibration. If wet drilling, supply a continuous water feed to cool the bit and flush debris; if dry drilling, pause periodically to avoid overheating and inspect the bit for wear.
Usage recommendations
Use appropriate personal protective equipment such as eye protection, gloves and respiratory protection when generating dust. Match drilling speed and pressure to the material; use water cooling for prolonged or multiple-hole work in stone, tile or glass to extend bit life. Follow the angle grinder or rotary tool manufacturer’s safety guidelines and the recommended maximum speed of 12,000 rpm.
