DeWalt vs Makita Rotary Tools - Which one for heavy-duty projects?

Hey folks, I'm looking to upgrade my rotary tool setup and can't decide between DeWalt's 20V Max and Makita's 18V LXT models. I do a lot of metal grinding, cutting, and polishing in my garage - nothing too fancy, but I need something that won't quit after an hour of use. Anyone have real-world experience with both? Battery life and durability are my top concerns.

Hank, you're comparing apples to oranges if you're just looking at voltage. The Makita's brushless motor runs at 25,000 RPM with only 0.8mm runout - that's precision DeWalt can't match. I've measured both with my dial indicator, and for detailed work like inlay or fine engraving, Makita's vibration control is superior. Their collet system also maintains concentricity better over time. But if you're just grinding rust off trailer hitches, maybe DeWalt's extra torque matters more?

On job sites, I see both brands daily. DeWalt's advantage is their battery ecosystem - if you're already invested in 20V tools, it's a no-brainer. Their rotary holds up to jobsite abuse better too; I've dropped mine off ladders and it still runs true. Makita feels more refined but their batteries cost more. Pro tip: Get the DeWalt kit with the flex shaft attachment - saves your wrists on overhead work. Either will handle your garage projects, Hank.

Thanks guys. Steve - I appreciate the precision specs but honestly I'd never notice 0.8mm runout. DrillMaster - good point about batteries, I do have two DeWalt 20V packs already. Anyone know about accessory compatibility? I've got a bunch of aftermarket bits and mandrels.

Standard 1/8" collets on both, so your existing bits should work. But Hank, if you're using cheap aftermarket accessories, you're already losing precision. Invest in quality name-brand abrasives - the tool is only as good as what you attach to it. Makita's electronic feedback actually adjusts RPM based on load, which extends disc life. Food for thought.
