KWB 051400 boor 10 mm × 120 mm voor glas en tegels

KWB 051400 is a 10 mm × 120 mm drill bit engineered for clean, precise drilling in brittle materials such as glass and ceramic tile. The bit's tip geometry and cutting angles are optimized to reduce chipping and cracking while producing accurate holes for sanitary fixtures, mounting hardware and glass panels. It is compatible with standard hand drills and drill presses when used at low speeds with steady feed.

Advantages

The drill bit's specialized tip and flute geometry provide controlled cutting action on glass and tile surfaces, reducing the risk of edge breakage. Its length allows for drilling through thicker tiles or medium-thickness glass panels while keeping the shank accessible in most chucks. The single-purpose design offers predictable results when proper speed and pressure are applied, delivering cleaner hole edges compared with general-purpose masonry or metal bits.

How to use

Secure the workpiece to prevent movement and, if possible, support the reverse side of glass or tile to reduce vibration and cracking. Fit the drill bit into the chuck and tighten firmly. Use a low rotational speed and apply steady, moderate pressure—avoid hammer action. For glass, consider using water as a coolant to reduce heat build-up; for glazed tile, begin drilling on a small starter mark or with masking tape to prevent skidding. Withdraw the bit periodically to clear debris and maintain cutting efficiency.

Recommendations

Always wear eye protection and appropriate gloves when drilling brittle materials. Start at low speed and increase feed only if the bit progresses smoothly. Avoid applying excessive lateral force. If drilling through particularly hard or tempered glass, verify material suitability first, as tempered glass can shatter and may require specialist tooling or methods.
