Achieve Flat Concrete Resurfacing and High-Speed Roughening with Maximum Ergonomics
Eliminate back strain and dramatically accelerate your surface preparation with the Bosch HS1909-12 SDS-Max® One-Piece Bushing Tool. 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.
Forged 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.
Key Features
- Extended Ergonomic Comfort: Generous 12.5-inch reach minimizes lower back bending, allowing operators to run heavy ground-level leveling tasks comfortably.
- Aggressive 25-Tooth Geometry: Features a 1-3/4" square head layout designed to rapidly pulverize concrete skin, scale, and high spots in fewer passes.
- Monolithic One-Piece Forging: Crafted entirely from a single block of high-strength alloy steel to remove weak joints and prevent head detachment under heavy impact.
- Universal SDS-Max Precision Shank: Guarantees a rigid, low-play interface for professional SDS-max drive tools, optimizing torque and impact delivery.
- OSHA Silica Compliance Support: Engineered for plug-and-play integration with the Bosch HDC300 extraction shroud attachment to maintain a safe, dust-free site.

PRO-TIP: When leveling or texturing a concrete slab with a 25-tooth bushing head, always keep the tool body completely vertical and use wide, gliding orbital patterns. Holding the bit at a sharp stationary angle or applying excessive downward body pressure can cause a few outer teeth to gouge deep craters into the substrate, leading to inconsistent texturing finishes and premature uneven wear on your alloy steel teeth!
