Diablo Flat Chisel DMAMXCH1030 1x12 Inch SDS-Max Rotary Hammer Bit (Heat Treated Steel Concrete Demolition Masonry Chipping Scaling Reinforcement)

Diablo DMAMXCH1030 1" x 12" SDS-Max Flat Demolition Chisel

The Diablo DMAMXCH1030 1-inch by 12-inch SDS-Max flat chisel delivers high-impact concrete scaling, mortar chipping, and reinforcement clearing in commercial demolition applications. Manufactured from specially heat-treated high-grade alloy steel, this rugged rotary hammer accessory withstands intense continuous impact energy without premature edge dulling or shank fracture. Featuring an optimized 1-inch flat cutting lip and an industrial 12-inch overall reach, it transfers maximum striking energy directly to concrete foundations, CMU block, and structural mortar beds in both corded and high-voltage cordless SDS-Max hammer drills.

Best Used For:

• Concrete Slab and Wall Scaling: Removing uneven slab ridges, leveling formwork pour seams, and stripping thick mortar beds efficiently.
• Rebar and Reinforcement Clearing: Chipping cured structural concrete away from steel rebar cages and tensioning cables for retrofit repairs.
• Masonry Joint Restoration and Demolition: Channeling brick mortar joints, knocking down cinder block walls, and carving utility troughs with directional control.

Key Performance & Safety Features

• Specialized Thermal Heat Treatment: Strengthens the alloy steel core to maximize fracture resistance under high-impact demolition cycles.
• Optimized 1-Inch Flat Cutting Edge: Provides controlled material removal and precise lateral tracking for uniform surface scaling.
• Universal SDS-Max Drive Shank: Delivers positive locking engagement and 100% direct energy transfer on all standard SDS-Max rotary hammer chucks.
• Extended 12-Inch Structural Length: Provides increased reach and leverage for deep floor trenching and tight corner demolitions.
• Corded and Cordless Optimization: Engineered to maximize battery runtime and impact efficiency on high-voltage cordless hammer platforms.
• Lateral Shock Resistance: Resists bending and binding stress when prying out cracked masonry sections and heavy aggregate.

Technical Specifications

Pro-Tip: Apply a light dab of chisel grease to the SDS-Max shank notches before inserting into your hammer chuck to prevent friction overheating, binding, and premature barrel wear during long demolition runs.
