Kivipora KWB 242138

The KWB 242138 masonry drill bit is an SDS Plus shank hammer drill designed for drilling into masonry materials such as brick and concrete. It has an 8 mm diameter and a self-centring tip for precise starts. The bit features high-temperature brazing and a multi-phase spiral that promotes efficient debris removal while limiting friction, heat build-up and vibration. It is certified by the German drill bit testing organisation (PGM) and meets standards of the German Institute of Building Technology.

Advantages

The SDS Plus shank provides secure tool engagement for hammer drills and rotary hammers. High-temperature brazing increases tip durability and wear resistance. The multi-phase spiral geometry improves chip evacuation to maintain drilling speed and reduce clogging. The self-centring tip ensures accurate positioning without pilot holes, and the construction minimises vibration and heat for longer service life.

How to use

Fit the KWB 242138 drill bit into an SDS Plus compatible hammer drill or rotary hammer and ensure it locks into the chuck. Select the hammer-drilling mode for masonry. Position the self-centring tip on the marked spot, start drilling at low speed to establish the hole, then apply steady pressure and allow the tool to work while maintaining vertical alignment. Periodically withdraw the bit to clear debris if drilling deep holes. Replace the bit when wear or loss of cutting performance is observed.

Recommendations

Use appropriate personal protective equipment including safety glasses, hearing protection and gloves. Match drill speed and hammer settings to the material; avoid excessive force which can overheat the bit. For reinforced concrete, use progressive drilling and inspect the bit regularly for wear.
