Masonry drill bit kwb ROCKER 044640

The kwb ROCKER 044640 masonry drill bit is a tungsten-carbide-tipped drill designed for drilling in concrete, masonry and natural or reconstituted stone. It is high-temperature brazed and features laterally and vertically secured carbide plates with an asymmetrical profile spiral to remove waste efficiently. The bit is suitable for use in both rotary and impact (hammer) drills and has a chemical black finish with a ground spiral for improved performance when drilling hard materials such as granite and limestone.

Advantages

The high-temperature brazed, tungsten carbide tip and secured TC plates provide wear resistance and long life when drilling abrasive materials. The asymmetrical profile spiral and chip-removing design optimise debris removal, reducing binding during drilling. The construction is resistant to hammer action, making the bit suitable for both standard rotary drilling and impact drilling, while the chemical black finish helps protect the surface and reduce corrosion.

Suitable for (tasks / use cases)

• Drilling holes in concrete for anchors and fixings
• Installing fixtures in masonry walls
• Creating openings in natural and reconstituted stone
• Work on limestone and granite surfaces where a durable drill bit is required

How to use

Secure the kwb ROCKER masonry drill bit in the appropriate drill chuck and select the correct drill speed and mode for the material (use hammer/impact mode for harder masonry if available). Mark the drilling position, start at low speed to create a guide, then increase speed and apply steady pressure without forcing the bit. Periodically withdraw the bit to clear dust and debris for more efficient drilling and to reduce heat build-up. For deeper holes, remove accumulated dust more frequently.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, gloves, hearing protection) and a dust extraction or mask when drilling. Match drill diameter and speed to the material and application; allow the bit to cool between prolonged uses to maintain tip life.
