Masonry drill bit kwb ROCKER 044740

The kwb ROCKER 044740 masonry drill bit is a tungsten-carbide tipped tool designed for drilling into hard materials such as concrete, brick, natural and reconstituted stone, limestone and granite. Manufactured to ISO 5468, the bit is suitable for use with rotary and impact (hammer) drills and is supplied as a single piece. Its asymmetrical profile spiral and chip-removing geometry support efficient waste removal during drilling while a chemical black finish and ground spiral enhance durability and cutting stability.

Advantages

The drill bit features high-temperature brazed, laterally and vertically secured carbide plates for resistance to impact and wear. An asymmetrical spiral profile improves chip evacuation and reduces clogging, and the right-hand rotation design ensures consistent drilling performance across masonry materials. The chemical black finish provides surface protection and the ground spiral increases precision when starting and during continuous drilling.

Suitable for

• Drilling into concrete and reinforced concrete
• Creating holes in brick and masonry walls
• Working with natural stone, reconstituted stone and limestone
• Use with rotary drills and hammer/impact drills

How to use

Select a drill with appropriate power and a compatible chuck for the kwb ROCKER 044740. Mark the drilling point and, where necessary, start at low speed to establish the hole. Apply steady axial pressure without excessive lateral force and use the hammer/impact mode only when recommended for the material. Periodically withdraw the bit to clear chips and avoid overheating; for deep holes clear debris more frequently. Keep the drill bit aligned with the hole to maintain accuracy.

Usage recommendations

For best results, use the kwb ROCKER 044740 with a drill that offers controlled speed and an effective hammer mechanism when working in concrete. Wear appropriate personal protective equipment (eye protection, dust mask and hearing protection) and remove debris regularly to preserve bit life. Avoid overheating by pausing intermittently on long or demanding drilling tasks.
