Diablo Scaling Chisel DMAMXCH1000 3 x 12 Inch (SDS Max Shank Hardened Alloy Steel Flat Demolition Blade Thin Set Mortar Concrete Cleaning)

Diablo DMAMXCH1000 3-Inch x 12-Inch SDS-Max Flat Scaling Chisel

The Diablo DMAMXCH1000 3-Inch x 12-Inch SDS-Max Flat Scaling Chisel is a heavy-duty surface demolition tool engineered to strip away tile mortar, hardened thin-set, scale, and concrete flashings. Forged from heat-treated hardened alloy steel with an SDS-Max shank interface, a 3-inch wide flat scaling blade, and a 12-inch overall working length, this demolition bit operates in corded and cordless SDS-Max rotary hammers. Manufactured in Switzerland, this specialized scaling chisel solves slow manual scraping, edge dulling, and shank breakage challenges during high-impact commercial floor renovation and masonry cleanup.

Best Used For:

• Thin-Set & Tile Mortar Stripping: Removing hardened tile adhesive, thin-set beds, and linoleum backing from concrete subfloors.
• Concrete Surface & Form Cleaning: Chipping away dried concrete splatters, formwork flashings, mortar droppings, and rust scale from jobsite surfaces.
• Masonry & Plaster Demolition: Scraping stucco, exterior plaster coatings, and loose masonry scale from vertical brick and cinder block walls.

Key Performance & Safety Features

• 3-Inch Wide Flat Scaling Blade: Broad scraping geometry covers significant surface area per impact stroke to accelerate floor coating removal.
• Precision SDS-Max Shank Interface: Universal SDS-Max drive shank transfers high impact energy directly from the rotary hammer piston without drive slip.
• Specialized Heat-Treated Alloy Steel: Thermal conditioning process strengthens the tool body to withstand continuous shock loads without bending or shattering.
• Self-Sharpening Edge Profile: Blade design maintains a thin, aggressive scraping edge throughout high-duty demolition cycles.
• 12-Inch Extended Reach Length: Provides leverage and clearance for comfortably scraping floor beds and tight wall intersections.

Technical Specifications

Pro-Tip: Maintain a shallow 20-to-30-degree angle relative to the floor slab during thin-set removal so the 3-inch scaling blade slides under the mortar layer without gouging the underlying concrete deck.
