Diablo Bull Point Chisel DMAMXCH1180 12 Inch SDS-Max Rotary Hammer Bit (Hardened Steel Concrete Breaking Masonry Demolition Foundation Chipping)

Diablo DMAMXCH1180 12" SDS-Max Bull Point Demolition Chisel

The Diablo DMAMXCH1180 12-inch SDS-Max bull point chisel focuses high-impact striking energy onto a concentrated focal point to fracture cured concrete slabs, foundation footings, and structural masonry walls. Forged from high-grade alloy steel and strengthened through a specialized thermal heat-treatment process, this rotary hammer demo bit resists shank snapping and tip mushrooming under continuous heavy hammering. Engineered with an industry-standard SDS-Max drive shank and an optimized 12-inch reach, it delivers direct energy transfer across corded and high-voltage cordless demolition hammers during commercial trenching, foundation breaking, and rebar clearing tasks.

Best Used For:

• Reinforced Concrete Slab Fracturing: Initiating stress cracks and breaking up cured 4-inch to 6-inch concrete slabs, driveways, and commercial footings.
• Foundation Demolition and Trenching: Piercing heavy aggregate foundations and carving deep plumbing or electrical trenches through basement slabs.
• Rebar and Embedment Excavation: Chipping structural concrete away from steel rebar grids, anchor bolts, and embedded structural columns during building retrofits.

Key Performance & Safety Features

• Concentrated Point Geometry: Pyramidal bull point tip directs 100% of the rotary hammer impact energy into a single spot for immediate material cracking.
• Proprietary Thermal Heat Treatment: Fortifies the entire alloy steel body to prevent brittle fractures and shank shearing under extreme lateral shock.
• Direct Energy Transfer: Precision-machined SDS-Max shank minimizes kinetic power loss between the hammer striker and the target workpiece.
• Extended 12-Inch Barrel Length: Provides deep penetration and optimal leverage for prying fractured concrete chunks apart in floor trenches.
• Corded and Cordless Efficiency: Low-friction profile maximizes battery runtime and blows-per-minute efficiency on modern cordless rotary hammers.
• Debris Ejection Fluting: Tapered body shoulders push fractured concrete dust and loose aggregate outward to prevent bit jamming in deep boreholes.

Technical Specifications

Pro-Tip: Never use a bull point chisel as a continuous prying lever once it penetrates concrete; drive the point in until the material fissures, pull back, and reposition 2 to 3 inches away to rapidly break off manageable chunks without binding the steel shank.
