Masonry drill bit kwb ROCKER 044660

The kwb ROCKER 044660 masonry drill bit is a single-piece, tungsten carbide-tipped drill designed for effective drilling in concrete, masonry and natural stone. Built to ISO 5468 standards, this drill bit combines a high-temperature brazed tip with laterally and vertically secured carbide plates and an asymmetrical spiral profile to enhance chip removal and maintain drilling precision. Its chemical black finish and ground spiral provide resistance to wear and reliable performance in both rotary and impact drilling modes.

Advantages

The drill bit’s tungsten carbide tip and secure brazing deliver durable cutting performance and extended lifetime under repeated hammering. An asymmetrical profile spiral and chip-removing geometry reduce clogging and speed up drilling through dense materials. The chemical black finish provides additional surface protection, while the ground spiral ensures consistent centring and smooth feed during operation.

Suitable for

• Drilling holes in concrete and reinforced concrete
• Work on brick, blockwork and general masonry
• Drilling into natural stone, granite and reconstituted stone
• Use with both rotary drills and hammer/impact drills

Key specifications

• Tungsten carbide tipped cutting edge
• High-temperature brazed tip with lateral and vertical plate securing
• Conforms to ISO 5468 drill geometry
• Asymmetrical spiral profile for efficient chip evacuation
• Chemical black surface finish
• Ground spiral for stable tracking and reduced walking
• Hammer-resistance suitable for impact drilling

How to use

Select a drill size appropriate for the hole required and clamp the bit securely in the drill chuck. Start drilling at low speed to establish the hole and then increase speed or engage the hammer function as appropriate for the material. Apply steady pressure without forcing the bit; allow the carbide tip and spiral geometry to remove chips efficiently. Withdraw the bit periodically to clear debris and reduce heat build-up for longer tool life.

Usage recommendations

For best results when drilling dense concrete or granite, use a drill with adequate impact energy and maintain moderate feed pressure. Keep the bit clean from dust and debris, and replace the bit if the carbide tip shows heavy wear or chipping. Use appropriate personal protective equipment, including eye and hearing protection, when operating rotary or impact drills.
