Masonry drill bit KWB 039700, diameter 10 mm, 1 pc

KWB masonry drill bit 039700 is a single 10 mm diameter carbide-tipped drill designed for drilling into brick, concrete and natural or artificial stone. Made for use with both hammer and rotary drills, the bit features a half‑round spiral flute for efficient dust and debris removal and a high‑temperature brazed tungsten carbide tip for impact resistance. The grey shot‑blasted surface improves handling and wear characteristics. Supplied as one piece, this drill bit is suited to common construction and renovation tasks such as installing anchors, conduits and fixtures.

Advantages

The tungsten carbide tip and high‑temperature brazing provide durability and reliable cutting performance in masonry materials. The smoothly formed half‑round spiral assists in fast waste removal to maintain drilling speed and reduce heat build-up. Shot‑blasted surface treatment improves grip in chucks and offers additional abrasion resistance. The bit’s design supports both rotary and impact drilling modes, giving flexibility for different tools and jobsite conditions.

Suitable for

• Drilling holes for wall anchors and plugs in brick or concrete
• Installing electrical conduits and cable routes through masonry
• Fixing shelves, brackets and fixtures to stone or block walls

How to use

Select a drill or hammer drill with appropriate speed and set the tool to hammer mode when working in concrete or dense masonry. Mark the drilling point and start at low speed to create a guide, then increase to medium speed while applying steady pressure; avoid excessive force that could overheat the tip. Periodically withdraw the bit to clear debris and allow cooling. For deep holes, remove accumulated dust with a brush or compressed air. Secure the bit properly in the drill chuck before use.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, hearing protection and a dust mask when drilling masonry. Match drill diameter to the anchor or fixing being installed and allow the carbide tip to cool between prolonged runs. Store the bit in a dry place and replace when tip wear reduces performance.
