DeWalt DWE402 Angle Grinder vs Makita GA4530 Angle Grinder

The DeWalt DWE402 is the stronger grinder for heavy cutting and grinding: its 11 A motor and 4.6 lb body give it noticeably more muscle than the Makita's 6 A. The Makita GA4530 is lighter at 4.0 lbs, shorter at 10-1/2 in, and its slide switch with lock-on is easier to run for long sessions. Both spin 4-1/2 in wheels at 11,000 RPM with a 5/8"-11 spindle, so wheel choice is identical. Owners of both call them solid and durable; the DeWalt's paddle safety catch draws complaints, and the Makita trades power for comfort.

  • Choose the DeWalt DWE402 if you cut and grind steel, pipe or masonry regularly and want the most power in a 4-1/2 in body.
  • Choose the Makita GA4530 if you want a lighter, shorter grinder with a lock-on slide switch for lighter jobs and longer sessions.

What reviewers say

DeWalt DWE402 Angle Grinder

  • 4.3 / 533 ratings

Reviewers rate it 4.3 out of 5 and describe it as well built and powerful, with smooth, low-vibration operation and a comfortable grip. The main complaint is the awkward safety catch on the trigger.

What people mention
  • PowerPraisedOwners say the 11 amp motor cuts pipe and tile quickly and cleanly.
  • VibrationPraisedReviewers report smooth, low-vibration running for more precise cuts.
  • GripPraisedThe small gripping surface and two-position side handle are called comfortable.
  • SwitchCriticisedThe safety catch on the paddle switch is awkward to defeat.

Makita GA4530 Angle Grinder

  • 4.2 / 520 ratings

Ratings for the GA4530 average 4.2 out of 5, with owners praising its light weight, smooth motor and simple slide switch. Complaints center on vibration and the lack of a brake or speed control.

What people mention
  • WeightPraisedOwners like the 4.0 lb body for one-handed use and overhead work.
  • VibrationCriticisedLong grinding sessions leave hands buzzing; the 7.5 m/s² rating is felt.
  • SwitchMixedThe slide switch and lock-on are handy, but some find it easy to bump.
  • Speed controlCriticised

Questions and answers

Which is better for cutting steel pipe?
The DeWalt DWE402. Its 11 A motor holds speed better through thick steel, and the tool-free wheel release speeds up disc swaps between cuts.
Which is easier to use for long sessions?
The Makita GA4530. It weighs less, is shorter, and its slide switch locks on so you don't grip a trigger the whole time.
Which lasts longer?
Both are durable, but the DeWalt adds dust ejection and auto-off brushes that protect the motor, which favors it in dusty grinding work.
Do they take the same wheels?
Yes. Both use 4-1/2 in wheels on a 5/8"-11 spindle and run at 11,000 RPM, so discs and most accessories interchange.
Is the DeWalt worth stepping up to?
If you cut or grind metal often, yes. The extra amperage and tool-free wheel changes matter on real jobs. For occasional light work, the lighter Makita is enough.
Can either be used for sanding or wire brushing?
Yes. Both accept 4-1/2 in sanding discs and up to a 3-1/2 in wire cup brush on the Makita; the DeWalt handles the same Type 27 and Type 1 accessories.
