An 80mm wide SDS Max chisel built for serious breaking and chasing work. Fits all SDS Max rotary hammers and demolition hammers. Ideal for removing tiles, concrete screeds, blockwork, and anything else that needs a proper hiding.
The 80mm SDS Max extra wide chisel is the go-to bit when you need to shift material fast across a broader face. At 80mm wide and 300mm in length, this chisel gives you a wide strike zone without sacrificing penetration — useful when you’re lifting floor tiles, stripping screeds, or opening up blockwork where a narrow chisel would have you going back and forth all day. If you’ve ever tried to remove a full floor of ceramic tiles with a 25mm moil point, you’ll appreciate what an 80mm SDS Max extra wide chisel brings to the job.
It fits the SDS Max toolholder system, which is the chunky end of the SDS range. SDS Max machines are typically the larger demolition and combi hammers — the kind you pick up two-handed for serious breaking work. The locking mechanism is positive and secure, so there’s no wobble or slippage mid-swing, and changing bits takes seconds without tools.
Where the 80mm SDS Max Extra Wide Chisel Does Its Best Work
This chisel is particularly well-suited to any trade that regularly deals with surface removal and structural preparation. Floor layers and tilers use it for lifting adhesive-bedded tiles from concrete slabs. Building contractors reach for it when breaking out sections of render or screed. It’s also handy for chasing wide channels in blockwork or concrete when you need the clearance for larger conduit or pipework runs.
Build Quality and Design
The chisel is forged for impact work and hardened at the tip to handle repeated hammer blows without deforming quickly. The flat wide blade transfers the hammer’s energy efficiently across the full cutting width, which makes short work of brittle materials like tiles and cured screed. At 300mm, the shank gives enough length to keep the hammer body well clear of the work surface, which saves your knuckles and protects the machine’s chuck from grit and debris.
Straightforward tool, does exactly what it says. At this price it’s worth having a spare on site.
Pro Tip: If the chisel starts skating across hard tiles rather than biting in, drop the hammer to chisel-only mode and angle the blade at about 30 degrees to the surface rather than flat on — you'll get a clean edge rather than a shattered mess.
This chisel is used across construction, refurbishment, and groundworks wherever material needs to be broken out or lifted from a surface. Common jobs include removing floor and wall tiles, stripping cement screeds, breaking out sections of concrete, chasing blockwork for large conduit runs, and general demolition prep work. It's a daily tool for groundworkers, building contractors, tilers, and anyone operating a large SDS Max demolition or combination hammer on site.

Key Specifications
Chisel width: 80mm
Overall length: 300mm
Shank: SDS Max
Hardened tip for impact work
Not suitable for: Not compatible with SDS Plus machines — the SDS Max shank is larger and will not fit SDS Plus toolholders. Not intended for drilling or core work.
Fit the chisel into the SDS Max toolholder by inserting the shank fully until it clicks into place. Set the hammer to chisel-only mode, not rotation. Position the blade at a shallow angle to the surface for tile and screed removal, or more directly for breaking out blockwork. Let the machine do the work — forcing it harder rarely speeds things up and just tires you out faster.
For large floor areas, work in rows and keep the chisel moving rather than dwelling in one spot. Clear broken material regularly so the blade isn't working through its own debris. Check the tip periodically during extended use, and if you notice the edge deforming or the bit losing bite, it's time to swap it out.
Set the hammer drill to chisel-only mode before fitting the bit
Insert the SDS Max shank fully into the toolholder until it locks with an audible click
Position yourself with a firm two-handed grip and stable footing
Angle the chisel blade slightly rather than flat against the surface for better bite on tiles and screed
Apply steady forward pressure and let the hammer's impact do the work
Work systematically across the surface in rows to avoid loose debris interfering with progress
Clear broken material from the work area regularly
Inspect the chisel tip during breaks and replace if visibly deformed or worn
Will this chisel fit my SDS Plus hammer drill?
No. The SDS Max shank is physically larger than SDS Plus and will not fit an SDS Plus toolholder. SDS Max chisels are designed for larger two-handed demolition and combination hammers. Check your machine's toolholder type before ordering.
Is this chisel suitable for chasing channels in brick or blockwork?
Yes, it works well for chasing wide channels where you need clearance for larger conduit or pipework. For narrow cable chases, a thinner flat chisel or dedicated chasing disc will give a cleaner result, but for anything 60mm and above this chisel does the job without fuss.
The chisel is manufactured from forged alloy steel with a hardened and tempered cutting tip designed to withstand repeated high-impact blows from SDS Max demolition and combination hammers. The SDS Max shank uses a larger slot-and-ball retention system compared to SDS Plus, providing a more secure lock in high-energy applications. At 80mm wide, the flat blade geometry distributes impact force across a broad face, which is effective for fracturing surface-bonded materials such as tiles, screed, and render.
