Bosch Diamond Blade DB441C 4 Inch Segmented Concrete Brick Block Cutting (14500 Max RPM Circular Saw Angle Grinder Attachment)

Bosch DB441C 4-Inch Segmented Diamond Cut-Off Blade for Concrete Brick Block Asphalt

The Bosch DB441C 4-Inch Segmented Diamond Blade is an industrial masonry cutting disc engineered to execute rapid wet and dry cuts through concrete, brick, cinder block, and asphalt. Rated for a maximum speed of 14,500 RPM, this 0.079-inch thick diamond wheel features a segmented rim profile that ejects slurry and debris to minimize thermal friction during heavy-duty cutting passes. Designed with a universal multi-arbor layout supporting 5/8-inch, 7/8-inch, and 20mm tool spindles, this blade attaches directly to circular saws, angle grinders, and compact high-speed saws for tough jobsite masonry installations.

Best Used For:

• Concrete Block & Brick Masonry Cutting: Trimming concrete pavers, clay bricks, and cinder blocks to size during wall construction and hardscaping.
• Asphalt Patching & Joint Saws: Scoring expansion joints and clean border edges in asphalt driveways and concrete slabs.
• Handheld Angle Grinder Slotting: Cutting narrow chase channels into brick walls and concrete foundations for conduit and plumbing runs.

Key Performance & Safety Features

• Debris-Clearing Segmented Rim: Deep gulping gullets between diamond segments rapidly expel dust and slurry to prevent blade binding and heat buildup.
• 14,500 High-RPM Rating: High-speed steel core construction safely withstands the rotational forces of high-speed circular saws and angle grinders.
• Universal Multi-Arbor Fitment: Includes knockout bushings to accommodate 5/8-inch, 7/8-inch, and 20mm motor arbors.
• Wet & Dry Operation Versatility: Formulated with a tough metallic matrix bond that performs smoothly under dry grinding or water-suppressed wet cutting.
• Industrial Diamond Grit Matrix: High-grade diamond concentration extends segment life when cutting through abrasive sand-lime bricks and stone.
• Vibration-Dampening Core: Stiffened steel plate design minimizes blade flutter and chatter to produce clean, controlled cuts.

Technical Specifications

Pro-Tip: When cutting dry asphalt or green concrete, maintain constant forward motion without forcing the saw to prevent soft aggregate buildup from loading the gullets between segments.
