Maximize Mass Demolition Yields with Industrial-Grade Bull Point Chisel Power

Tackle large-scale concrete chipping and structural break-up jobs with the Bosch HS1813B20 12-Inch Spline Shank Rotary Hammer Bull Point Chisel Bit 20-Pack. Designed specifically for mechanical tradesmen, pool builders, utility contractors, and commercial demolition teams, these high-impact bull point points specialize in localized stress fracturing. By channeling your rotary hammer's complete impact force straight into a sharp, focused tip, these chisels easily shatter dense unreinforced concrete, heavy foundation slabs, masonry brick configurations, aggregate blocks, and structural grout lines. Buying this multi-pack guarantees your fleet stays completely outfitted on high-production construction projects, eliminating costly jobsite interruptions.

Engineered to withstand brutal continuous cyclic shock, each chisel in this bulk kit is manufactured from a single piece of premium-grade forged alloy steel. Bosch implements a proprietary, advanced thermal heat-treatment process that hardens the carbon-steel core to significantly resist tip dulling while maintaining structural ductility to eliminate catastrophic shattering under high trade loads. The universal 3/4-inch hex by 21/32-inch round spline shank profile delivers a rock-solid, non-slip interface for conventional spline-drive demolition hammers and large rotary hammers. Trust these Italian-made heavy-duty consumables to track accurately, clear hard masonry substrates at rapid penetration rates, and deliver reliable jobsite durability to your commercial crews.

Key Features

  • 20-Piece Bulk Fleet Pack: Keeps heavy construction and demolition teams continuously supplied across large-scale commercial job sites.
  • Concentrated Point Geometry: Directs your tool's maximum joules of impact force to a single point, allowing for fast starting holes and mass fracture runs.
  • Universal Spline Shank Fit: Precision-ground 3/4" hex x 21/32" round shank matches standard professional spline-drive demolition and rotary hammer chucks.
  • Proprietary Heat-Treat Forging: Premium industrial alloy steel formulation engineered to combat structural fatigue and eliminate catastrophic bit breaks under load.
  • One-Piece Core Structural Balance: Forged from a single piece of premium steel to transfer kinetic energy efficiently without dampening vibrations.

PRO-TIP: Bull point chisels are explicitly meant for initiating deep fault cracks and breaking bulk chunks of stone or unreinforced slabs. Avoid using them to pry or lever concrete beds like a crowbar once the tip is driven down! Relying on mechanical prying forces puts excessive lateral stress across the bit throat, which can strain your tool's spline retainer chuck and crack even high-tensile heat-treated alloy steel shanks!
