Masonry drill bit kwb ROCKER 1 pc Right hand rotation

The kwb ROCKER masonry drill bit is a tungsten carbide tipped, hammer-resistant drill designed for rotary and impact drills. It is manufactured to ISO 5468 standards with high-temperature brazed carbide plates secured laterally and vertically, and a chemical black finish. The asymmetrical profile spiral and ground flute geometry provide efficient chip removal and reliable performance when drilling into concrete, brick, natural and reconstituted stone, limestone and similar masonry materials.

Advantages

Carbide cutting edges brazed at high temperature ensure long life and wear resistance. The laterally and vertically secured carbide plates reduce the risk of tip damage under impact. The asymmetrical spiral and ground flute promote fast evacuation of debris for cleaner, more accurate holes. The chemical black finish helps protect the bit surface and reduces friction during drilling.

Suitable for

• Drilling holes in concrete and reinforced concrete
• Drilling into brick and masonry walls
• Work on natural and reconstituted stone
• Installing anchors, dowels and wall plugs

Key specifications

• Tungsten carbide tipped cutting head
• High-temperature brazed carbide plates, secured laterally and vertically
• Asymmetrical profile spiral with ground flute for chip removal
• Chemical black surface finish
• Designed for rotary and impact (hammer) drilling
• Right-hand rotation

How to use

Mark the drilling point and select an appropriate drill speed and mode for the material and diameter. Use the bit in a compatible rotary or rotary-percussion (hammer) drill, applying steady forward pressure without excessive side load. Start drilling at low speed to create a guide, then increase speed as the bit penetrates. Periodically retract the bit to clear debris for continued efficient cutting.

Usage recommendations

For best results, use appropriate personal protective equipment (eye and hearing protection, dust mask) and an appropriate drill with an SDS or compatible chuck. Match drill speed and hammer function to the material type; reduce hammer action in brittle stone. Replace the bit if cutting performance deteriorates or visible damage appears on the carbide tip.
