DeWalt DWE402W Angle Grinder vs Makita 9557PB Angle Grinder

Buy the DeWalt DWE402W if you cut and grind hard and often; its 11 amp motor and dust ejection system are built for heavy removal. Buy the Makita 9557PB if you want a lighter, smoother-running grinder for general shop and job-site work. The DeWalt has the edge on power and tool-free wheel changes; the Makita has the edge on weight, vibration control and sealed construction. Owners of both report long service life, and the Makita's 1-year warranty is the shorter of the two.

  • Choose the DeWalt DWE402W if you grind or cut steel regularly and want maximum power plus wrench-free wheel changes.
  • Choose the Makita 9557PB if you want a lighter grinder with a sealed gear case and a large paddle switch for all-day handling.

Questions and answers

Which is better for cutting rebar and steel plate?
The DeWalt. Its 11 amp motor holds speed under load better than the Makita's 7.5 amp motor, and the tool-free wheel change speeds up swaps between cuts.
Which one is easier to use overhead?
The Makita. At 4.6 lbs it is roughly a pound lighter than the DeWalt, and its rated 7.0 m/s2 vibration is lower, which matters in long overhead sessions.
Which lasts longer in dusty work?
Both are built for dust. The Makita seals the gear case with labyrinth construction and coats the armature with zig-zag varnish; the DeWalt ejects dust through its intake vents. Owners of both report years of service.
Is the DeWalt worth stepping up to from the Makita?
Yes if you grind hard material daily and want the extra power, quick wheel changes and longer warranty. No if weight and smooth running matter more than torque.
Do they use the same wheels and accessories?
Yes. Both take 4-1/2 inch wheels on a 5/8-11 spindle and run at 11,000 RPM, so discs, flap wheels and wire cups fit either one.
Which has the better switch for long grinding?
The Makita, because it locks on for continuous operation. The DeWalt's paddle switch has a safety lock-off but no lock-on, so you hold it the whole time.
