Specifically engineered with an extended 12.5-inch operational length, this premium attachment allows contractors to work comfortably on ground-level concrete slabs with significantly less bending, reducing operator fatigue on high-production job sites. Featuring an aggressive 1-3\/4 inch square head containing 25 precision-formed teeth, this monolithic powerhouse concentrates massive structural impact force to pulverize raised high spots, level un-even joints, remove thick chemical toppings, and texture concrete surfaces for new cosmetic overlays. It is an indispensable consumable tool for decorative concrete professionals, highway restoration crews, and structural masonry installers.\u003c\/p\u003e\n\u003cp\u003eForged from a single piece of premium-grade, heat-treated alloy steel, the Bosch HS1909-12 is structurally built to withstand the punishing continuous stress generated by high-joule SDS-max demolition breakers and rotary hammers. This advanced monolithic construction ensures uniform kinetic energy transmission straight from your hammer's piston assembly to the work surface, eliminating common fracture points found on multi-component welded bushing heads. To protect your crew from hazardous respirable crystalline silica exposure and maintain a clean, professional workspace, this bit pairs seamlessly with the optional Bosch HDC300 dust-extraction sleeve shroud as part of the OSHA Table 1 compliant PRO+GUARD™ dust collection collection framework.\u003c\/p\u003e\n\u003ch3 style=\"color: #004b87;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Ergonomic Comfort:\u003c\/strong\u003e Generous 12.5-inch reach minimizes lower back bending, allowing operators to run heavy ground-level leveling tasks comfortably.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAggressive 25-Tooth Geometry:\u003c\/strong\u003e Features a 1-3\/4\" square head layout designed to rapidly pulverize concrete skin, scale, and high spots in fewer passes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMonolithic One-Piece Forging:\u003c\/strong\u003e Crafted entirely from a single block of high-strength alloy steel to remove weak joints and prevent head detachment under heavy impact.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal SDS-Max Precision Shank:\u003c\/strong\u003e Guarantees a rigid, low-play interface for professional SDS-max drive tools, optimizing torque and impact delivery.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOSHA Silica Compliance Support:\u003c\/strong\u003e Engineered for plug-and-play integration with the Bosch HDC300 extraction shroud attachment to maintain a safe, dust-free site.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"color: #004b87;\"\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e(1) Bosch HS1909-12 SDS-Max® 1-3\/4\" 25-Tooth One-Piece Concrete Bushing Tool\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"color: #004b87;\"\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width: 58.75%; border-collapse: collapse; border: 1px solid rgb(221, 221, 221); font-family: sans-serif;\" height=\"548\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"background-color: #004b87; color: white;\"\u003e\n\u003cth style=\"padding: 8px; text-align: left; border: 1px solid rgb(221, 221, 221); width: 34.347%;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding: 8px; text-align: left; border: 1px solid rgb(221, 221, 221); width: 65.653%;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background-color: #fff0f5;\"\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid rgb(221, 221, 221); font-weight: bold; width: 34.347%;\"\u003eBrand Name\u003c\/td\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid rgb(221, 221, 221); width: 65.653%;\"\u003eBosch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid rgb(221, 221, 221); font-weight: bold; width: 34.347%;\"\u003eModel Number \/ MFG Part #\u003c\/td\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid rgb(221, 221, 221); width: 65.653%;\"\u003eHS1909-12\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #fff0f5;\"\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid rgb(221, 221, 221); font-weight: bold; width: 34.347%;\"\u003eBit Tool Type\u003c\/td\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid rgb(221, 221, 221); width: 65.653%;\"\u003eBushing Chisel Bit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid rgb(221, 221, 221); font-weight: bold; width: 34.347%;\"\u003eShank Type Compatibility\u003c\/td\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid rgb(221, 221, 221); width: 65.653%;\"\u003eSDS-max® Only\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #fff0f5;\"\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid rgb(221, 221, 221); font-weight: bold; width: 34.347%;\"\u003eTotal Length\u003c\/td\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid rgb(221, 221, 221); width: 65.653%;\"\u003e12.5 in.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid rgb(221, 221, 221); font-weight: bold; width: 34.347%;\"\u003eBushing Head Profile\u003c\/td\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid rgb(221, 221, 221); width: 65.653%;\"\u003e1-3\/4 in.
