Τρυπάνι τοίχου KWB 244646 1.6 cm

HB 44 SDS Plus Hammer Drills, 460/400 mm — masonry drill bit KWB 244646 with a 1.6 cm (16 mm) diameter, designed for drilling in hard materials such as brick and concrete. The bit features an SDS Plus shank and a self‑centring tip, with manufacturing and brazing methods that provide durability and accurate hole placement. The multi‑phase spiral removes debris efficiently while reducing friction, heat build‑up and vibration; the product meets standards set by German testing organisations for building tools.

Advantages

The KWB 244646 offers an SDS Plus connection for secure retention in compatible rotary hammer tools and a self‑centring tip that simplifies drilling start. High‑temperature brazing and a multi‑phase spiral geometry improve wear resistance and chip evacuation, which supports consistent drilling performance in masonry. Reduced friction and vibration contribute to longer tool life and steadier operation.

How to use

Fit the drill bit into an SDS Plus compatible rotary hammer according to the tool manufacturer's instructions. Mark the drilling point and position the self‑centring tip on the mark. Use the rotary hammer in hammer‑drill mode appropriate for masonry; apply steady, moderate pressure without forcing the bit. Periodically withdraw the bit to clear debris if drilling deep holes and allow the bit to cool during extended use.

Recommendations

Use appropriate personal protective equipment (safety goggles, hearing protection and dust mask) and select drill speeds and hammer settings recommended for masonry. Replace the bit when wear affects drilling performance or tip geometry.
