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.\u003c\/p\u003e\n\u003cp\u003eEngineered 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.\u003c\/p\u003e\n\u003ch3 style=\"color: #004b87;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e20-Piece Bulk Fleet Pack:\u003c\/strong\u003e Keeps heavy construction and demolition teams continuously supplied across large-scale commercial job sites.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConcentrated Point Geometry:\u003c\/strong\u003e Directs your tool's maximum joules of impact force to a single point, allowing for fast starting holes and mass fracture runs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal Spline Shank Fit:\u003c\/strong\u003e Precision-ground 3\/4\" hex x 21\/32\" round shank matches standard professional spline-drive demolition and rotary hammer chucks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProprietary Heat-Treat Forging:\u003c\/strong\u003e Premium industrial alloy steel formulation engineered to combat structural fatigue and eliminate catastrophic bit breaks under load.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOne-Piece Core Structural Balance:\u003c\/strong\u003e Forged from a single piece of premium steel to transfer kinetic energy efficiently without dampening vibrations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"color: #004b87;\"\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e(20) Bosch HS1813 12\" Spline Shank Bull Point Chisel Bits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003ciframe width=\"1094\" height=\"615\" src=\"https:\/\/www.youtube.com\/embed\/I7eKEFR5t7I\" title=\"Bosch PROFACTOR™ 18V Hitman™ SDS-max® 1-9\/16 In.
