The DeWalt DWA0807B10 SDS Max 18x400mm Flat Chisel 10Pc is a professional demolition accessory kit made for heavy concrete and masonry work, with ten flat chisels in one pack that keep you moving hard and steady on big tear-out jobs. It’s built with an aggressive SDS Max shank that locks up tight in compatible rotary hammers, so you’re not fighting bit slip — you’re busting material smart.

When you’ve got to strip out concrete, chip away stubborn brick, or dress up rough stone, this flat chisel set delivers consistent strike and controlled material removal — no wild chatter, no sketchy results — just predictable performance that trades rely on.

Key Features:

• SDS Max Shank - Locks solid into SDS Max hammers so impact force goes where it needs to go, not into your grip.
• 18 mm Diameter - Thick enough to take serious impacts without bending yet nimble enough for precision chipping.
• 400 mm Length - Gives reach into deep spots without twisting you up.
• Flat Chisel Profile - Ideal for surface smoothing and removing concrete or mortar with controlled cuts.
• 10-Piece Pack - Keeps you productive — swap chisels without downtime when edges wear.

Applications

Look, when you’re on a tear-out or surface prep gig and need something more than a drill bit, this SDS Max flat chisel gets stuck into concrete spalling, screed removal, brick and block surface clean-up, and general demolition tasks with rotary hammers designed for SDS Max tooling.

Why Choose This Model

Here’s the thing — not every set of chisels holds up when you’re pounding all day. The DWA0807B10 set is heat-treated so each blade section resists cracking under repeated impact, and because it’s packed in tens, you’ve got spares on hand without running back to the truck. That matters a lot when you’ve got a schedule to hit.
