DEWALT Diamond Cup Wheel DW4777T 5 Inch Turbo Grinding Saw Accessory (5/8-11 Threaded Arbor 12200 RPM Concrete Masonry Surface Preparation Tool)

High Concentration Turbo Diamond Segments for Rapid Concrete Leveling

The DEWALT DW4777T is a 5-inch XP Extended Performance turbo diamond cup grinding wheel engineered for high-speed material removal and surface preparation on concrete and masonry. This premium accessory utilizes an exceptionally high diamond concentration anchored to a heat-treated steel body to maximize structural stability and minimize tool vibration. Designed for use with standard angle grinders featuring a 5/8-inch-11 threaded arbor, it provides the industrial durability required for flattening rough construction joints, stripping dense surface coatings, and preparing aggregate walls at up to 12,200 Max RPM.

Best Used For:

• Slab Joint Leveling: Grinding down raised seams, high spots, and rough form lines on poured concrete floors.
• Surface Prep Coating Removal: Stripping thinset mortar, specialized sealants, residual adhesives, and heavy industrial coatings from masonry substrates.
• Masonry Edge Shaping: Smoothing, chamfering, and preparing rough edges on bricks, cinder blocks, and concrete retaining walls.

Key Performance & Safety Features

• XP Diamond Matrix: Advanced industrial-grade diamond concentration extends service life and prevents premature segment smoothing under heavy loads.
• Turbo Rim Geometry: Continuous turbo segment layout provides a more rapid, fluid cut rate than single row alternatives.
• Heat-Treated Steel Base: Robust structural alloy body resists thermal distortion and high mechanical torque during aggressive dry grinding.
• Vibration Damping Construction: Balanced body design lowers rotational wobble to preserve angle grinder bearing longevity and reduce operator fatigue.
• Broad Footprint Segments: Enhanced segment surface area distributes contact forces uniformly to ensure a flatter, more uniform finish.

Technical Specifications

Pro-Tip: Keep the angle grinder moving in consistent, circular motions across the workpiece; resting static in one place can instantly gouge deep valleys into concrete slabs that require costly patch compounds to correct.
