Bosch Concrete Hammer Steel HS1520 1-3/4 Inch Square 3/4 Hex Shank 16-Tooth 9-1/4 Inch Length Bushing Tool Demolition Heavy Duty Masonry Bit For Slabs

Industrial-Grade Concrete Surface Preparation and Texturing Bit for Demolition Hammers

The Bosch HS1520 1-3/4 Inch Square 16-Tooth Concrete Hammer Steel Bushing Tool is a heavy-duty masonry boring attachment engineered to roughen, level, and texture interior and exterior concrete surfaces. Equipped with a standard 3/4-inch hex shank and a robust one-piece alloy steel frame, this 9-1/4 inch demolition tool removes high spots and prepares dense slabs for bonding overlays without structural breaking. A proprietary heat-treat process tempers the integrated 16-tooth square configuration head to resist thermal fracturing and withstand the extreme mechanical percussive forces of commercial hammer units.

Best Used For:

• Concrete Overlay Bonding Prep: Textures slick or polished smooth poured concrete slabs to maximize chemical adhesion for new compound overlays.
• Slab Leveling and High-Spot Milling: Knocks down raised surface imperfections, excess seam deposits, and irregularities across residential or commercial floor footprints.
• Masonry Scaling and Cleaning: Aggressively clears away scale, dried mortar accumulations, and hard slag on commercial brick, stone block, and industrial joints.

Key Performance & Safety Features

• 16-Tooth Precision Grid: Structured layout concentrates descending percussive striking force onto a dense area for rapid scarification fracturing.
• Forged One-Piece Alloy Steel: Monolithic body construction isolates shock distribution paths to eliminate joint stress points and head breakage.
• Proprietary Thermal Treatment: Industrial hardening process maintains structural cutter profile limits under constant heavy percussive heat expansion.
• 3/4-Inch Hex Interface Profile: Solid hex mounting base prevents unsafe slipping in heavy demolition hammer chuck mechanisms to safely optimize driver energy delivery.
• Industrial Wear Resilience: Solid carbon alloy composition preserves teeth sharpness across dense masonry materials and structural stone beds.

What's Included

• (1) Bosch 1-3/4" Square x 9-1/4" Bushing Tool (HS1520)

Technical Specifications

Pro-Tip: Never hold the tool at a severe angle or utilize prying force during operation; maintain a perpendicular 90-degree stance relative to the concrete slab to allow the 16 teeth to displace percussive vibrational stress evenly across the solid platform.
