Muuripora KWB 242140

The KWB 242140 masonry drill bit is an SDS Plus hammer drill accessory designed for drilling into hard materials such as brick, concrete and natural stone. With a 10 mm diameter and robust construction, the bit features a self-centring tip and multi-phase spiral flutes to improve debris evacuation and reduce friction and heat during operation. The tip is high-temperature brazed and the design minimises vibration; the bit is certified by a German drill bit testing organisation and meets standards of the German Institute of Building Technology.

Advantages

The SDS Plus shank ensures secure tool retention in hammer drills and rotary hammers. A self-centring tip provides accurate starting and reduces wandering on masonry surfaces. Multi-phase spiral flutes optimise waste removal for cleaner holes and lower cutting resistance, while high-temperature brazing increases tip durability. The design reduces vibration and heat build-up, extending tool life and improving drilling consistency.

How to use

Fit the SDS Plus shank into a compatible hammer drill or rotary hammer and ensure it is locked securely. Start drilling at low speed to allow the self-centring tip to locate the hole, then apply steady pressure and increase speed as required. Use hammer function for concrete and masonry; withdraw periodically to clear debris and avoid overheating. Replace the bit when wear degrades performance or tip integrity.

Recommendations

Use appropriate personal protective equipment (safety glasses, ear protection, dust mask) and select drill speed and hammer power suited to the material. For deeper holes, pull the bit out regularly to remove dust and prolong bit life. Confirm compatibility of the SDS Plus shank with your drill model before use.
