## Summary description

Montolit FAJ12 is a 12 mm diamond wet drill bit designed for wet drilling applications in hard materials such as tile and ceramic. The bit requires water cooling during use to reduce heat and extend life, offering precise holemaking for installations, plumbing, and electrical fixtures. Compatible with standard rotary drills and suitable for professional and DIY tasks.

## Long description

Montolit FAJ12 diamond wet drill bit, 12 mm, is engineered for wet drilling in hard, brittle materials such as ceramic tiles, porcelain and glazed tile. The bit features a diamond-segment cutting tip that provides accurate, clean holes while water cooling reduces heat buildup and prolongs tool life. Designed for use with standard rotary drills and drill stands, this drill bit is intended for controlled, low-speed drilling where precision and chip-free edges are required for installations and repair work.
Advantages
The diamond cutting edge delivers fast penetration and consistent cutting performance on glazed and porcelain surfaces. Water cooling reduces friction and prevents overheating, which helps maintain diamond bond integrity and extends service life. The 12 mm diameter produces precise, round holes suitable for fixtures and pipe passages without excessive chipping when used at recommended speeds and with proper support. Compatibility with common drill chucks and mountings makes it easy to integrate into existing toolsets.
Suitable for
Drilling clean holes in ceramic and porcelain wall and floor tiles
Creating openings for plumbing pipes, faucets and shower fittings
Preparing holes for electrical boxes, conduit entries and mounting hardware
Professional tiling, bathroom and kitchen installations and DIY renovation tasks
Key specifications
Tip material: diamond-segment cutting edge for wear resistance on hard glazed surfaces
Drilling method: wet cooling required to control temperature and remove debris
Diameter: 12 mm for standard fixture and pipe clearances
Suitable materials: ceramic, porcelain, glazed tile and similar hard brittle materials
Shank type: compatible with standard rotary drill chucks and drill stands
How to use
Secure the tile or workpiece on a flat, stable surface and mark the hole position. Fit the 12 mm Montolit diamond wet drill bit into a drill with a suitable chuck and set a low to moderate speed; high speeds increase the risk of overheating and chipping. Provide a continuous flow of water to the drilling area—either via a wet drilling rig, water feed, or periodic wetting—to cool the cutting edge and wash away slurry. Apply steady, light pressure and allow the bit to cut; do not force the tool. Withdraw periodically to clear debris if necessary, and finish the hole with a slow final pass for a clean edge.
Usage recommendations
Use with a drilling guide or drill stand for perpendicular holes and reduced vibration. Wear appropriate personal protective equipment (eye protection, gloves) and ensure water does not enter the drill motor. Replace the bit when cutting performance declines or if the diamond segment shows excessive wear.
