DeWalt 20V MAX Atomic Impact Driver Kit vs Milwaukee M18 Brushless 7-1/4 in. Circular Saw

These are different tools, so the real question is what you need to drive. The DeWalt DCF809C2 is a compact 1/4 in. impact driver for screws, lag bolts and self-tappers, while the Milwaukee M18 kit is a 7-1/4 in. circular saw for cutting lumber and sheet goods. Buy the DeWalt if your work is fastening; buy the Milwaukee if your work is cutting. Neither replaces the other, and owners of both lines praise the brushless motors and battery platforms.

  • Choose the DeWalt DCF809C2 if you need a light, short impact driver for driving screws and fasteners in tight spaces, and you want two batteries in the kit.
  • Choose the Milwaukee M18 saw if you need to cut 2x lumber, plywood or decking and want a cordless saw with two 5.0 Ah batteries and a rapid charger.

What reviewers say

DeWalt 20V MAX Atomic Impact Driver Kit

  • 4.5 / 517 ratings

Owners rate the DCF809 highly as a compact, powerful driver for its size. Most praise the torque and short head, while some wish the included batteries held more charge.

What people mention
  • TorquePraisedOwners say it drives long screws and lag bolts without bogging down.
  • SizePraisedThe short 5.1 in. head gets into stud bays and cabinet interiors.
  • BatteryMixedTwo batteries are welcome, but the 1.3 Ah packs run down quickly on heavy driving.
  • WeightPraisedAt about 2.1 lbs it is comfortable for overhead and one-handed work.

Milwaukee M18 Brushless 7-1/4 in. Circular Saw

  • 4.6 / 54,887 ratings

Owners of Milwaukee's 7-1/4 in. M18 saw generally rate it as a dependable job-site cutter with good power for its size. Most praise the brushless motor and battery compatibility; complaints center on weight and battery drain under heavy cutting.

What people mention
  • PowerPraisedOwners say the brushless motor handles framing cuts without bogging down.
  • WeightCriticisedReviewers note the saw gets tiring during long vertical or overhead work.
  • Battery lifeMixedTwo 5.0 Ah packs cover most jobs, but heavy cutting drains them fast.

Questions and answers

Which is better for building a deck?
You need both jobs done: the Milwaukee saw cuts the boards and the DeWalt driver fastens them. If you can only buy one first, start with the saw, since cutting is the harder task to do by hand.
Can the DeWalt driver replace a drill?
Not fully. It drives screws and fasteners well, but it has no chuck for drill bits, so you still need a drill for holes.
Which lasts longer on a charge?
The Milwaukee saw's 5.0 Ah batteries carry far more capacity than the DeWalt's 1.3 Ah packs, so the saw runs longer per charge. The DeWalt's small packs are light but need swapping sooner.
Is the Milwaukee saw worth stepping up to over a brushed saw?
Yes if you cut often. The brushless motor gives more power and runtime, and the two 5.0 Ah batteries and rapid charger keep you working.
Do the batteries work across other tools?
Yes. The DeWalt batteries fit the 20V MAX line and the Milwaukee batteries fit the M18 line, so staying in one platform pays off as your kit grows.
Which is easier to use in tight spaces?
The DeWalt driver. Its 5.1 in. body and 2.1 lbs weight fit where the 9 lb saw cannot go.

The saw feels solid, though the base and bevel detents are less precise than premium models.
