Masonry drill bit kwb ROCKER 044630

The KWB ROCKER 044630 masonry drill bit is a tungsten-carbide tipped drill designed for drilling in concrete, brick, natural and reconstituted stone, limestone and other masonry materials. It features high-temperature brazed carbide plates that are secured both laterally and vertically, an asymmetrical profile spiral for efficient chip removal, and a chemical black finish. The bit is suitable for use in rotary and rotary-impact (hammer) drills and is built to resist the stresses of impact drilling.

Advantages

The drill bit's tungsten carbide tip and high-temperature brazing provide wear resistance and long life when working with abrasive masonry. The laterally and vertically secured TC plates reduce the risk of tip displacement under load. The asymmetrical spiral profile and ground flute design improve dust and debris evacuation for cleaner, faster drilling. Compatibility with rotary and impact drills makes the bit versatile for both professional and DIY tasks.

• Drilling holes in concrete
• Drilling into brick and blockwork

How to use

Fit the KWB ROCKER 044630 into a compatible drill according to the drill manufacturer's instructions. Use right-hand rotation and apply steady pressure; allow the drill bit to cut without forcing to avoid overheating or premature wear. For impact drilling in concrete or brick, use the drill's hammer function. Periodically withdraw the bit to clear dust and debris and to check progress. Use appropriate personal protective equipment (safety glasses, gloves, dust mask) and follow site safety rules.

Usage recommendations

For longer tool life and cleaner holes, start with a pilot hole at low speed when drilling large diameters, avoid excessive pressure or prolonged continuous runs at high speed, and store the bit dry to prevent corrosion of the chemical black finish.
