## Long description

The KWB 499812 hole saw with a 12 mm diameter features a unitary body and diamond-particle coated cutting edge designed for drilling holes in hard materials such as porcelain, ceramic tiles, granite worktops, natural stone slabs and marble. Manufactured with industrial-grade diamond coating and accurate, highly concentric construction, this hole saw is intended for precise small-diameter drilling tasks and is supplied as a single piece in a blister pack.
Advantages
The diamond particle coating and solid one-piece construction provide long life and consistent cutting performance on very hard surfaces. High concentricity ensures accurate, clean holes with minimal wobble. The tool is suitable for wet drilling to extend bit life and reduce dust and heat.

Key specifications

How to use
Mark the drilling position and use a centre punch or pilot drill to prevent slipping. Fit the hole saw to a compatible arbor or drill chuck and run the drill at appropriate speed for the material—typically low to medium speed for stone and ceramic. Use continuous water cooling or intermittent water application to keep the cutting edge cool and to clear debris. Apply steady, moderate pressure and avoid forcing the tool; withdraw occasionally to remove slurry and check progress.
Usage recommendations
For best results on porcelain, granite and marble, use wet drilling and a sturdy drill with good speed control. Wear eye protection and a dust mask when dry cutting; for stone and glazed tiles wet cutting is recommended to prolong tool life and improve hole quality.
