Our take on the Milwaukee M18 Fuel 2831-21 (1x6.0Ah)

The Milwaukee M18 Fuel 2831-21 is an 18V cordless plunge cut saw with a 6.5-inch blade and a brushless motor that spins at 6,300 rpm. It cuts like a track saw without a cord: plunge depth control, bevel adjustment and a dust bag are built in, and it runs on Milwaukee's M18 battery platform. At about 9 lb with a 6.0Ah pack it is heavier than many corded track saws but frees you from an outlet. Reviewers rate its cut quality and power close to corded track saws, while noting the weight and the cost of entering Milwaukee's battery system.

Best forTrim carpenters and remodelers working without outletsM18 platform owners who want a track-compatible sawStraight cuts in sheet goods, doors and countertopsJobsite work where dust collection matters
Pros
  • Brushless Fuel motor with 6,300 rpm no-load speed
  • Plunge depth control and bevel adjustment for track-style cuts
  • Dust bag included and a port for a vacuum hose
  • Runs on the M18 battery platform, so one pack fits many tools
  • 6.5-inch blade handles common sheet-goods and trim cuts
Cons
  • Around 9 lb with the 6.0Ah battery, heavy for overhead or one-hand work
  • Needs a compatible track for the straightest cuts, sold separately
  • Premium tool; the bare tool plus battery and charger adds up
  • Depth and bevel adjustments take practice to set quickly

What reviewers say

Owners and reviewers treat the 2831-21 as one of the strongest cordless plunge saws, with cut quality close to corded track saws. Most criticism centers on weight and the cost of the battery system rather than performance.

What people mention
  • Cut qualityPraisedOwners report clean, accurate cuts in plywood and sheet goods, close to corded track saws.
  • WeightCriticisedReviewers say the saw is heavy with the 6.0Ah battery, which tires you in long or overhead work.
  • Dust collectionPraisedThe dust bag and vacuum port keep chips down, especially with a hose attached.
  • Battery platformMixedM18 owners like sharing packs across tools, but newcomers find the battery and charger cost steep.
  • Track useMixedCuts are straightest on a compatible track, which is sold separately and adds setup time.

Questions and answers

Does it come with a track?
No. The kit includes the saw, one 6.0Ah battery, a charger and a saw blade. A compatible guide track is sold separately.
Can it cut through 2x lumber?
At full plunge the 6.5-inch blade cuts roughly 2-1/4 inches deep, enough for dimensional lumber and most sheet goods. Deep cuts in thick stock may need two passes.
How does it compare with a corded track saw?
Cut quality and power are close, and you lose the cord. The trade-off is weight and dependence on charged M18 batteries.
Does the dust bag work well?
Yes for light cuts. For heavy sheet-goods work, attaching a vacuum to the port collects far more dust.
Is it worth it over the previous M18 plunge saw?
The Fuel version adds a brushless motor and more speed. If you already own M18 batteries, the bare tool is the sensible buy.
What battery does it use?
Any Milwaukee M18 pack. The kit ships with one 6.0Ah battery, and larger packs add runtime but also weight.
Where is the Milwaukee M18 Fuel 2831-21 (1x6.0Ah) cheapest?
