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.

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.
