Which is better for cutting steel and pipe?

The DeWalt. Its 11 A motor holds speed under load better than the Makita's 7.5 A. The Makita still cuts steel fine for lighter work.

Which is better for tile and concrete?

Both handle it at 11,000 RPM. The Makita's dust sealing suits gritty concrete work, and X-LOCK makes swapping between cutting and grinding wheels quick.

Both are durable. The Makita guards the motor and bearings better against dust. The DeWalt has oversized brushes with auto-off and a large spiral bevel gear.

Is the Makita worth stepping up to over the DeWalt?

Only if fast wheel changes and a lock-on switch matter to you. You give up motor power and gain convenience.

Can I use my existing wheels on the Makita?

Only with an X-LOCK-to-standard adapter. The DeWalt takes standard 5/8"-11 arbor wheels directly.

Which is easier on the hands for long jobs?

The Makita's lock-on switch means you don't hold the trigger, and its barrel is shaped for extended use. The DeWalt is lighter but its paddle must stay pressed.

DeWalt DWE402 Angle Grinder vs Makita GA4570 X-LOCK Angle Grinder

Buy the DeWalt DWE402 if you want the most power and torque in a 4-1/2 in grinder for heavy cutting and grinding. Buy the Makita GA4570 if fast, wrench-free wheel changes and a slide switch with lock-on matter more to you. The DeWalt has the stronger motor and a lighter body; the Makita has X-LOCK and better dust sealing. Owners of both call them solid, durable tools, and ratings sit close, with the DeWalt slightly ahead.

Choose the DeWalt DWE402 if you cut and grind steel, pipe or masonry often and want maximum power with a paddle switch that shuts off when released.
Choose the Makita GA4570 if you swap wheels constantly and want X-LOCK tool-free changes plus a lock-on slide switch for long sessions.
