Bosch Diamond Saw Blade DB4565S 4-1/2 Inch 7/8 Arbor (Segmented Rim 0.071 Thickness 13300 RPM Green Concrete Asphalt Soft Masonry Grinder Disc)

Industrial-Grade 4-1/2 Inch Segmented Rim Diamond Saw Blade for Green Concrete and Asphalt

The Bosch DB4565S 4-1/2-Inch Standard Segmented Rim Diamond Saw Blade functions as a commercial-duty abrasive masonry cutting disc engineered to slice through green uncured concrete, asphalt paving, lime sand bricks, and soft masonry. Constructed with a tensioned steel core plate and laser-welded diamond segments, this 7/8-inch round arbor blade operates on small angle grinders, circular saws, and cut-off tools at rotational speeds up to 13,300 RPM. Utilizing a 0.071-inch blade thickness and a 1-1/4-inch maximum cutting depth, the unit executes wet or dry slotting and expansion joint cuts while venting thermal friction through segment expansion slots.

Best Used For:

• Green Uncured Concrete Control Joints: Cutting early-entry expansion joints in freshly poured green concrete slabs to control random stress cracking.
• Asphalt Patching & Trenching: Slicing crisp edges in asphalt driveways, parking lots, and road surfaces for pipe trenching and asphalt repair.
• Soft Masonry & Lime Sand Brick Trimming: Executing high-speed dry cuts through soft clay bricks, sand-lime blocks, and soft masonry units.

Key Performance & Safety Features

• Abrasive Material Matrix Bond: Specially formulated metallic bond holds diamond grit firmly against abrasive asphalt and green concrete slurry.
• Tensioned Alloy Steel Core Plate: Computer-balanced steel body dampens lateral vibration and maintains plate rigidity during high-speed cutting.
• Segmented Rim Expansion Vents: Deep gullet spaces between segments dissipate operational heat and flush swarf out of deep cuts.
• 13,300 RPM Speed Capability: High-velocity rating ensures thermal stability and diamond matrix retention on corded and cordless angle grinders.
• Wet and Dry Application Range: Operates efficiently dry or wet to suppress crystalline silica dust during jobsite site preparation.

Pro-Tip: When cutting abrasive green concrete or asphalt patch borders, supply continuous water to the blade surface whenever possible. Wet cutting flushes highly abrasive aggregate slurry out of the 0.071-inch kerf, extending the metallic segment bond life and preventing premature diamond undercut at the steel core weld.
