## Long description

DeWalt DT9428-QZ is a single rotary hammer bit with a 26 mm diameter and 540 mm overall length, designed for drilling larger holes in masonry and concrete. Engineered for use with rotary hammers, this long bit enables deep and wide boreholes needed in structural and installation work. Supplied as one piece, it is suitable for contractors and tradespeople who require a durable tool for creating anchor, sleeve and service openings.
Advantages
The bit’s 26 mm cutting diameter and extended 540 mm length allow accurate drilling at depth while maintaining stability during rotary hammer operation. Its construction is optimized to withstand the impact forces of rotary hammers, providing consistent performance when penetrating concrete, brick and block. Being a single-piece design simplifies handling and bit replacement while keeping compatibility focused on rotary hammer chucks.

Key specifications
 Type: rotary hammer drill bit
 Cutting diameter: 26 mm
 Overall length: 540 mm
 Quantity: 1 piece
 Intended material: concrete, masonry (brick, block)
How to use
Fit the drill bit securely into the rotary hammer chuck according to the tool manufacturer’s instructions and confirm compatibility with SDS-plus or the appropriate chuck system. Mark the drilling location, position the bit perpendicular to the surface, and start drilling at low speed to establish the hole before applying full rotary hammer action. Use steady pressure without forcing the bit; allow the tool’s impact mechanism to perform the cutting. Periodically withdraw the bit to remove debris and prevent overheating while drilling deep holes.
Usage recommendations
Wear appropriate personal protective equipment including safety glasses, hearing protection and dust mask when drilling concrete or masonry. Use water suppression or a dust extraction system where required to reduce airborne dust. Select a rotary hammer with sufficient power and use correct speed/impact settings to match the 26 mm diameter and long 540 mm bit for optimal performance and extended bit life.
