Optimize Metal Fabrication Workflows And Blast Through Structural Weld Beads Instantly With Dust Defending Power

The DEWALT DWE402 is an 11-Amp corded 4.5-inch compact handheld angle grinder engineered for aggressive metal surface preparation and heavy-duty structural steel cutting. Operating at 11,000 RPM, this AC/DC powered tool utilizes a specialized dust ejection system to strip harmful metal fragments from internal air paths before they damage motor windings. The paddle switch configuration features an integrated safety lock-off mechanism, while the tool-free wheel flange enables rapid accessory changes without a spanner wrench.

Best Used For:

  • Structural Steel Cutting: Slicing through rebar, structural angle iron, and thick heavy-gauge carbon steel framing on construction locations.
  • Weld Seam Smoothing: Blending raw weld beads, removing industrial mill scale, and prepping metal pipe profiles for immediate joining.
  • Heavy Masonry Scoring: Prepping brick lines, trimming concrete blocks, and removing excess mortar joints when fitted with diamond abrasive wheels.

Key Performance & Safety Features

  • Industrial 11-Amp Motor: High-performance corded powertrain sustains a consistent 11,000 RPM velocity for deep grinding depth cuts.
  • Dust Ejection System: Automatically channels airborne metal particles out of intake ports to defend the internal copper coils from abrasive burnout.
  • One-Touch Rotation Guard: Permits immediate 360-degree rotational positioning around the disc tracking zone without needing separate mechanical adjustments.
  • Quick-Change Wheel Release: Lever-driven flange mounting system enables rapid, tool-free wheel removal to optimize jobsite swapping intervals.
  • Safety Lock Paddle Switch: Built-in toggle tab forces a manual release movement before trigger engagement to eliminate unprompted mechanical restarts.
  • Auto-Off System Brushes: Halts tool operations automatically when internal carbon wear reaches safety thresholds to prevent armature failure.

What's Included

  • DWE402 11-Amp 4-1/2 Inch Angle Grinder
  • Two-Position Side Assist Handle
  • One-Touch Protective Guard
  • Inner and Outer Wheel Flange Set
