DEWALT DW4999 7" x 1/4" x 5/8"-11 Type 27 Metal Grinding Wheel

The DEWALT DW4999 7-inch x 1/4-inch Type 27 depressed center metal grinding wheel removes excess weld buildup, bevels thick steel plates, and dresses torch-cut edges across structural steel, carbon alloy, cast iron, and ferrous metals. Formulated with high-performance aluminum oxide abrasive grains and a heavy-duty resinoid matrix, this commercial grinding disc delivers aggressive stock removal rates with extended wheel wear life under severe contact pressure. Constructed with three full sheets of reinforced structural fiberglass and an integrated 5/8"-11 threaded hub, it equips metal fabricators, pipefitters, and shipyard welders with rapid wheel spin-on mounting, smooth low-vibration operation, and maximum jobsite safety.

Best Used For:

  • Commercial Weld Bead Blending: Grinding down heavy structural welds, smoothing root passes, and cleaning fabrication joints on thick carbon steel plates.
  • Edge Beveling and Chamfering: Prepping heavy pipe ends, plate edges, and angle iron prior to welding assemblies in structural ironworking shops.
  • Torch-Cut Slag and Scale Removal: Dressing plasma-cut, oxy-fuel torch-cut, or shear-cut steel surfaces and stripping heavy surface oxidation from castings.

Key Performance & Safety Features

  • High-Performance Aluminum Oxide Grain: Delivers rapid material removal rates and extended abrasive wheel life across diverse ferrous metals.
  • Triple Fiberglass Mesh Reinforcement: Features three full structural sheets of woven fiberglass for exceptional burst strength and operator safety under high pressure.
  • Type 27 Depressed Center Profile: Allows aggressive grinding at 15 to 30-degree working angles without gouging adjacent workpiece surfaces.
  • Integrated 5/8"-11 Threaded Arbor Hub: Fast spin-on, spin-off threaded hub enables quick tool-free mounting directly onto commercial 7-inch angle grinders.
  • High Grain Concentration Balance: Precision wheel formulation ensures true-running concentric balance to minimize hand-arm vibration and machine spindle wear.
