DeWalt Diamond Saw Blade DW4725 4-1/2 Inch Disc (Continuous Rim 200X Life 7/8 Arbor Thin Kerf Concrete Brick Masonry Siding Angle Grinder Slicing)

DEWALT DW4725 4-1/2" Continuous Rim High-Performance Diamond Masonry Saw Blade

The DEWALT DW4725 4-1/2-inch continuous rim diamond masonry saw blade scores concrete surfaces, trims architectural face brick, cuts fiber cement siding planks, and shapes cinder blocks without edge breakout or rough chip marks. Engineered with an advanced high-performance diamond matrix that delivers up to 200X longer cutting life compared to conventional bonded abrasive wheels, this 7/8-inch arbor disc mounts directly on 4-1/2-inch angle grinders and compact handheld saws. Outfitted with an ultra-thin continuous rim profile that maximizes cutting speed at a constant depth while suppressing airborne jobsite dust, it equips commercial masonry contractors, tile setters, and exterior siding installers with clean, precise dry and wet cuts across delicate aggregate materials.

Best Used For:

• Masonry Siding and Fiber Cement Board Sizing: Crosscutting fiber cement lap siding, exterior composite trim, and cement backerboard panels with chip-free, smooth factory edges.
• Architectural Brick and Block Detailing: Trimming facing brick, mortar joints, and cinder block corners on small-scale masonry repairs and tuckpointing projects.
• Concrete and Tile Scoring on Angle Grinders: Executing controlled, dust-reduced expansion joint cuts and shallow relief channels in cured concrete flatwork and paver stones.

Key Performance & Safety Features

• 200X Extended Service Life: Advanced industrial diamond matrix withstands extreme friction heat and abrasive aggregate wear, outlasting bonded abrasive wheels by up to 200 times.
• Continuous Smooth Rim Profile: Uninterrupted diamond rim eliminates segment chatter to produce pristine, chip-free edge finishes in delicate masonry substrates.
• Dust-Reducing Thin Kerf: Narrow cutting width slices through stone and concrete faster while generating significantly less airborne particulate dust.
• Standard 7/8-Inch Arbor Interface: Universal center bore mounts securely to all standard 4-1/2-inch angle grinders, compact circular trim saws, and masonry cutters.
• Dry and Wet Cutting Capability: Formulated for continuous dry-cutting jobsite speed while fully supporting wet operation for slurry dust control.
• High-Speed Heat Dissipation: Tensioned alloy steel core plate resists thermal warping and dishing during extended high-RPM grinding passes.

Technical Specifications

Pro-Tip: When using this continuous rim blade on an angle grinder to trim masonry siding or brick, maintain a light touch and let the high spindle speed do the work; forcing the disc generates excess heat that can glaze over diamond grit, while light pressure keeps cutting diamonds fresh and sharp.
