## Summary description

DeWalt DT9409-QZ masonry drill bit, 16 mm diameter, supplied as a single piece for use with rotary hammers. Designed for drilling into masonry materials such as brick, concrete and stone. Intended for professional and DIY applications where a carbide-tipped masonry bit is required for clean, efficient drilling with a compatible SDS or rotary hammer system.

## Long description

DeWalt DT9409-QZ masonry drill bit, 16 mm diameter, is designed for use with SDS Max rotary hammers to drill into masonry, brick, concrete and natural or artificial stone. This single-piece carbide-tipped bit features a reinforced core and a four-flute helix that removes debris efficiently to maintain drilling speed. The solid two-cutter head, flanked by two individual cutting tips, provides reliable penetration and consistent hole quality for professional and DIY applications.
Advantages
The four-flute helix ensures fast debris evacuation and helps sustain a steady drilling rate in dense materials. A reinforced core increases impact and breakage stability for tougher jobs. The solid two-cutter carbide tip, supported by two additional cutting tips, delivers efficient cutting action and improved centring for accurate holes. The SDS Max shank ensures secure bit retention and compatibility with rotary hammers designed for this interface.
Suitable for
 Drilling holes in reinforced concrete for anchor installation
 Creating openings in brick and block walls
 Drilling through natural and artificial stone for fixing and through-holes
 Heavy-duty renovation and construction tasks requiring an SDS Max rotary hammer

How to use
Fit the DeWalt DT9409-QZ into the SDS Max chuck of a rotary hammer and ensure it is securely locked before operation. Mark the drilling position, start at low speed or use the hammer-only mode to create a pilot indent if required, then apply steady pressure while operating the rotary hammer at the appropriate hammering and rotation settings for the material. Withdraw the bit periodically to clear accumulated debris and reduce heat build-up. Allow the tool and bit to cool during extended continuous use.
Usage recommendations
Use appropriate personal protective equipment including eye protection, hearing protection and dust extraction or respiratory protection when drilling. Match drilling speed and hammering force to the material: reduce feed pressure in very hard or reinforced concrete and maintain steady pressure in masonry. Inspect the carbide tip for wear and replace the bit when cutting performance declines to preserve hole accuracy and avoid excessive stress on the rotary hammer.
