Circle cutter drill bit Wolfcraft 8911000

The Wolfcraft 8911000 Circle cutter drill bit is a diamond-coated annular bit designed for drilling precise 68 mm diameter holes up to 25 mm deep in wall and floor tiles, including glazed tiles. It has a 10 mm round shank for quick fastening in a cordless screwdriver chuck and an integrated centring drill that can be removed without tools after initial positioning. The tool body is turned from solid material and coated with industrial diamonds for durability and accurate cutting. An integrated sponge must be soaked before use to supply water during drilling for cooling and dust suppression. The bit is TÜV-tested for safety and quality.

Advantages

The diamond coating on a solid-turned body provides long service life and high cutting precision. The removable centring drill enables exact positioning and fast transition to annular cutting. The 10 mm round shank fits typical cordless screwdriver chucks for quick changeover. The integrated sponge supplies cooling water during use and reduces dust. TÜV testing confirms product safety and manufacturing quality.

Suitable for

• Drilling socket or fixture openings in ceramic wall tiles and glazed floor tiles

How to use

Soak the integrated sponge in water until fully saturated before starting. Secure the 10 mm round shank in the cordless screwdriver chuck. Start with the centring drill to position the hole accurately; once the pilot is established, remove the centring drill by hand and continue drilling with the annular cutter. Apply steady, moderate pressure and maintain rotation at appropriate speed for tile cutting. The soaked sponge will release water during drilling to cool the diamond coating and suppress dust. After use, clean and dry the bit and sponge before storage.

Usage recommendations

Use with a cordless screwdriver that accepts a 10 mm round shank and avoid dry drilling. Keep the sponge wet throughout the operation, work at moderate speed, and secure the workpiece to prevent movement for precise, safe holes.
