Masonry drill bit DeWalt DT9423-QZ for rotary hammer, diameter 2.4 cm, 1 pc

DeWalt DT9423-QZ masonry drill bit is a 24 mm diameter, 540 mm length bit designed for use with rotary hammers (SDS Max compatibility). Built for drilling into concrete, brick, masonry and natural or artificial stone, this single-piece masonry drill bit combines a reinforced core and a multi-flute design to maintain drilling speed and stability in heavy-duty anchoring, fixing and installation tasks.

Advantages

The drill bit features a solid two-cutter carbide tip flanked by two individual cutting tips to provide fast and efficient cutting performance. A four-flute helix and maximum flute entry enable rapid debris evacuation to reduce clogging and maintain momentum during extended drilling. The reinforced core increases impact and breakage resistance, delivering greater durability under high-impact rotary hammer use.

Suitable for

• Drilling holes for heavy-duty anchors and fixings in reinforced concrete
• Creating through-holes and installation passages in brick or masonry walls
• Making anchor or dowel holes in natural and artificial stone
• Contractor and construction site rotary hammer drilling applications

How to use

Fit the drill bit into an SDS Max-compatible rotary hammer following the tool manufacturer's instructions and ensure the bit is securely locked in the chuck. Mark the drilling position, start at low speed to create a guide recess if required, then apply steady pressure while operating the hammer function. Use intermittent extraction of the bit to clear debris if drilling deep holes, and let the tool and bit cool periodically during extended use.

Usage recommendations

Wear appropriate personal protective equipment, including safety goggles, hearing protection and gloves. Use a vacuum or dust extraction system when possible to reduce silica dust. Match drill speed and hammer settings to the material: higher impact settings for reinforced concrete, and moderate settings for brick or softer masonry. Inspect the bit for wear or damage before use and replace when cutting performance declines.
