DeWalt DWE402 Angle Grinder vs Makita 9557PB Angle Grinder

Buy the DeWalt DWE402 if you cut and grind metal or masonry regularly and want the extra power; its 11 A motor and 11,000 RPM give it more reserve than the Makita's 7.5 A. The Makita 9557PB is the better pick for lighter, longer sessions: it weighs the same 4.6 lbs but is shorter at 10-3/4 in, has a lock-on switch for continuous work, and labyrinth seals plus zig-zag varnish protect the motor from dust. Both are proven 4-1/2 in grinders with 5/8-11 spindles; the DeWalt feels stronger, the Makita feels more refined and easier to control.

  • Choose the DeWalt DWE402 if you cut or grind steel, pipe and masonry often and want the most power in a compact 4-1/2 in body.
  • Choose the Makita 9557PB if you want a lighter-feeling, dust-sealed grinder with a lock-on switch for long grinding and sanding sessions.

Questions and answers

Which is better for cutting metal?
The DeWalt DWE402. Its 11 A motor holds speed better under load, and the tool-free wheel release speeds up disc changes between cuts. The Makita handles light metal work fine but bogs down sooner on thick stock.
Which lasts longer?
Both are durable. The Makita's labyrinth seals and zig-zag varnish are aimed squarely at dust and debris, which is what kills grinders. The DeWalt counters with a dust ejection system and auto-off brushes that stop the tool when they wear out.
Is the Makita worth stepping up to over the DeWalt?
They sit in the same class, so it is a trade, not a step up. You give up motor power and tool-free wheel changes for a shorter body, a lock-on switch and better dust sealing.
Which is better for sanding and wire brushing?
The Makita, mainly because of its lock-on switch, which saves your hand during long sessions. Both use 4-1/2 in discs and 5/8-11 spindles, so accessories fit either one.
Which is easier to hold for long periods?
They weigh the same, so it comes down to shape. The Makita is about an inch shorter and easier to choke up on; the DeWalt's small gripping surface is comfortable but its body is longer.
Do both use the same wheels?
Yes. Both take 4-1/2 in wheels with a 5/8-11 arbor, so the same cutting and grinding discs fit either grinder.
