Bosch Diamond Saw Blade DB4564S 4-1/2 Inch 7/8 Arbor (Segmented Rim 0.063 Thickness 1.25 Cut Depth Wet Dry Hard Reinforced Concrete Stone Cutter)

Industrial-Grade 4-1/2 Inch Segmented Rim Diamond Saw Blade for Reinforced Concrete

The Bosch DB4564S 4-1/2-Inch Standard Segmented Rim Diamond Saw Blade functions as a commercial-duty abrasive cutting disc engineered to slice through rebar-reinforced concrete, structural red brick, hard fieldstone, and masonry blocks. Constructed with an industrial synthetic diamond matrix laser-bonded to a computer-tensioned steel core plate, this 7/8-inch round arbor blade operates on small angle grinders during high-speed masonry alteration work. Utilizing a 0.063-inch blade thickness and a 1.25-inch maximum cutting depth, the unit executes wet slurry or dry slotting passes while dissipating thermal friction through deep segment expansion gullets.

Best Used For:

• Reinforced Concrete Trenching: Slicing rebar-embedded concrete floor slabs and wall footings with fast diamond matrix engagement.
• Structural Brick & Block Modification: Executing clean crosscuts through hard-burned red clay face bricks, refractory bricks, and concrete masonry units (CMU).
• Hard Natural Stone Trimming: Milling straight, accurate edges in granite slabs, fieldstone, quartz, and slate using small angle grinders.

Key Performance & Safety Features

• Hard Aggregate Diamond Formulation: Industrial synthetic diamond matrix engineered specifically for rapid material removal in dense, rebar-reinforced concrete.
• Computer-Tensioned Steel Core: Reduced-vibration alloy plate maintains core rigidity to prevent wheel chatter and plate wobble during heavy feed pressure.
• Segmented Rim Expansion Gullets: Open slot geometry vents operational heat and clears abrasive concrete slurry out of deep cuts.
• Wet and Dry Application Range: Operates efficiently dry or wet to suppress crystalline silica dust during jobsite masonry cutting.
• Universal 7/8-Inch Arbor Fit: Mounts directly onto standard 4-1/2-inch corded and cordless small angle grinder output spindles.

Pro-Tip: When making deep 1.25-inch cuts through hard, rebar-reinforced concrete with a 4-1/2-inch angle grinder, maintain a light hand and let the diamond segment matrix shear the material naturally. Forcing the blade through steel rebar generates extreme friction heat that glazes the diamond matrix; periodically dressing the blade in soft masonry or cinder block exposes fresh diamond cutting edges.
