Stenborr KWB 244648

Masonry drill bit KWB 244648 — SDS Plus shank hammer drill bit with self-centring tip, designed for drilling into hard masonry and concrete. The 18 mm diameter (1.8 cm) and multi-phase spiral flute provide efficient waste removal, reduced friction and heat build-up, and lower vibration during use. The tip is high-temperature brazed for durability, and the bit is certified by the German drill bit testing organisation (PGM) and meets standards of the German Institute of Building Technology.

Advantages

The KWB 244648 combines an SDS Plus shank for secure tool engagement with a self-centring tip for accurate starts. Its multi-phase spiral geometry evacuates dust effectively, reducing clogging and maintaining drilling speed. High-temperature brazing on the tip increases wear resistance and extends service life. The design minimises vibration and heat generation, improving comfort and performance in prolonged drilling tasks.

Key specifications

How to use

Securely insert the SDS Plus shank into a compatible rotary hammer drill. Select hammer or rotary-hammer mode according to the material and required drilling speed. Begin drilling with light pressure to allow the self-centring tip to establish the hole, then apply steady, moderate force. Clear debris from the hole as needed and avoid prolonged continuous operation to limit overheating. Replace the bit if tip damage or excessive wear is observed.

Recommendations

Use appropriate personal protective equipment (safety glasses, ear protection and dust mask). For reinforced concrete, use a suitable carbide-tipped bit and check compatibility with the hammer drill. Store the bit in a dry place to prevent corrosion and inspect the tip before each use.
