Diamond drill bit Wolfcraft 5918000 — 1 pc, right-hand rotation

Wolfcraft Diamond drill bit 5918000 is a single-piece, right-hand rotation annular bit with a diamond-coated cutting edge designed for precise drilling in tiles and glazed surfaces. The tool is intended for use with cordless screwdrivers and similar portable drivers; its round 10 mm shank enables quick clamping in a chuck. The solid-turned body is coated with industrial diamonds to provide accurate cutting and extended service life. The bit has a cutting depth of 30 mm and is supplied individually in a polybag with a hanging hole.

Advantages

The diamond coating on the cutting edge ensures clean, accurate holes in ceramic and glazed tiles while the solid-turned body provides rigidity and durability. The round 10 mm shank allows fast and secure mounting in common cordless screwdriver chucks. A 30 mm cutting depth gives control for most sanitary and cable-bushing tasks without over-penetration. The product has passed TÜV testing, indicating compliance with recognised safety and quality standards.

• Drilling holes for bathroom fittings through ceramic or glazed wall and floor tiles

How to use

Secure the diamond annular bit in the chuck of a compatible cordless screwdriver or drill with a 10 mm round-shank capacity. For tile drilling, start at low speed to establish the hole and increase speed as the bit engages the surface, applying steady, moderate pressure. The bit is designed for right-hand rotation. To maintain the diamond coating and reduce heat, use wet cutting when possible and keep drilling intervals short to avoid overheating the coating. Ensure the workpiece is supported and that drilling is performed with appropriate protective equipment for personal safety.

Usage recommendations

For best protection of the diamond coating and optimal hole quality, use the annular bit with a water feed or the Wolfcraft guide accessory designed for wet cutting (guide sold separately). Allow the bit to cool between uses and avoid dry continuous drilling on hard glazed surfaces to prolong service life.
