Masonry drill bit kwb SUPER ROCKER 050670
The kwb SUPER ROCKER 050670 masonry drill bit is a tungsten-carbide-tipped bit designed for drilling in hard materials such as concrete, masonry, natural and reconstituted stone, granite and limestone. It has a hexagon shank for secure chucking and an asymmetrical spiral profile to remove chips efficiently. The bit is suitable for use in both standard rotary and impact (hammer) drills and features a chemical black finish and ground spiral for consistent cutting performance.
High-temperature brazed tungsten carbide tip with lateral and vertical securing of the carbide plates provides long life and resistance to impact loads. The asymmetrical, chip-removing spiral reduces clogging and improves drilling speed. Hexagon shank prevents slipping in the chuck, and the chemical black finish adds surface protection. The design supports use in hammer drills while maintaining stable rotary performance.
Mark the drilling position and secure the workpiece if necessary. Fit the kwb SUPER ROCKER 050670 into the drill chuck, ensuring the hexagon shank is fully tightened. Start drilling at low speed to establish the hole, then increase speed as required. For deep holes, withdraw the bit periodically to clear debris and allow cooling. When drilling with hammer function, maintain firm, even pressure without excessive force.
Use appropriate personal protective equipment (safety glasses, dust mask, gloves) and, when drilling in concrete or stone, consider wet drilling or dust extraction to reduce silica dust. Select drill speed and hammer setting according to the material hardness and hole diameter to prolong bit life.
