Bosch Diamond Blade DB4541S 4-1/2 Inch Arbor Cut Off Disc (Segmented Rim Wet Dry Cutting Concrete Pavers Brick Block Slicing Tool Shaft Assembly)

Bosch DB4541S 4-1/2" Standard Segmented Rim Diamond Masonry Cutting Blade

The Bosch DB4541S 4-1/2-inch standard segmented rim diamond blade executes universal rough cutting in cured concrete slabs, hard masonry blocks, interlocking paving stones, and soft brick across wet and dry jobsite applications. Engineered with an upgraded, taller industrial diamond segment height and a standard 7/8-inch arbor hole, this 0.29-pound cut-off wheel operates safely up to 13,300 maximum RPM while maintaining stable tracking under heavy loads. Outfitted with deep open segment gullets that clear concrete dust and slurry efficiently to prevent thermal binding, it equips masonry contractors, hardscape installers, and demolition crews with rapid, general-purpose cutting performance across angle grinders, circular saws, and high-speed cut-off machines.

Best Used For:

• Concrete Slab and Expansion Joint Cutting: Slicing deep cuts, floor joints, and retaining wall sections on residential and commercial construction sites.
• Interlocking Paver and Hardscape Sizing: Trimming concrete pavers, flagstones, and architectural retaining wall blocks to exact landscaping specifications.
• Masonry Block and Soft Brick Alterations: Cutting through cinder blocks, clay bricks, and mortar joints rapidly with minimal feed pressure.

Key Performance & Safety Features

• Upgraded Taller Diamond Segment Height: Expanded segment profile packed with embedded industrial diamonds extends operating life and lowers overall cost-per-cut.
• Segmented Open Gullet Design: Deep rim slots provide rapid debris and slurry evacuation, reducing cutting friction and operating temperatures.
• Wet and Dry Operational Flexibility: Engineered matrix supports water-cooled wet cutting as well as dry cutting based on jobsite dust management requirements.
• High-Speed 13,300 Maximum RPM: Dynamically balanced alloy steel core plate ensures stable, vibration-free tracking on high-power cutting tools.
• Standard 7/8-Inch Arbor Mount: Universal center arbor hole fits securely onto professional angle grinders, circular saws, and high-speed cutters.

Technical Specifications

Pro-Tip: When dry cutting dense masonry or concrete blocks with a 4-1/2-inch angle grinder, let the natural weight of the grinder do the cutting without forcing the blade sideways; excessive side pressure can warp the steel core and reduce blade lifespan.
