The DeWalt DT6838 SDS Max Bush Hammer Chisel is a heavy-duty demolition attachment built for surface profiling and roughening in concrete and stone, and it chomps through tough material without complaining. What you’re actually getting is a purpose-made bush hammer head with a 45 mm width and a 240 mm length, sized just right for breaking and texturing work on big slabs of masonry.

With a SDS Max connection this thing locks solidly into compatible rotary hammers so you’re not wrestling it on the job site — that matters a lot when you’re doing repetitive surface prep and want stability as much as impact force.

Key Features:

• SDS Max Shank - Locks into SDS Max hammers for secure engagement and consistent force transfer.
• 45 mm Cutting Width - Wide enough to roughen broad surface areas efficiently.
• 240 mm Length - Gives you reach and leverage in deeper chiselling and demolition tasks.
• Bush Hammer Head Profile - Designed for aggressive surface texturing and mechanical bonding prep.
• Heat-Treated Steel - Toughened body that hangs tough under repeated impact.

Applications

This isn’t your weekend DIY toy — the bush hammer chisel is for breaking up and profiling concrete, stone, brick, block work and other masonry where you need that rough, keyed surface for coatings, overlays or mortars to stick.

Why Choose This Model

Here’s the thing: you’ve got chisels and then you’ve got chisels built for real job site punishment. The DeWalt DT6838 doesn’t just withstand repeated hits — its heat-treated, hardened steel body handles them with minimal wear. That means fewer trips back to the workshop for replacements or sharpening.

Who Should Buy This

If you’re a concrete contractor, mason, surface prep pro or tradesperson who spends hours shaping, texturing and prepping large slabs of masonry and concrete, this chisel is built for that kind of workload — the DT6838 SDS Max Bush Hammer delivers the surface profile and material removal you need without burning through tools.
