Summary

A subcompact 12V impact driver sold as a bare tool, built for electricians, plumbers and HVAC techs who work in tight spaces and already own M12 batteries. Check what it takes to get into the platform first: the tool needs an M12 battery and charger that are not in the box.

Strengths

  • Hands-on testing by Pro Tool Reviews confirmed the speed and torque figures.
  • The 5-inch head reaches into tight spaces where full-size drivers will not fit.
  • Owners say it out-drives many mid-range 18V impact drivers.
  • The Tri-LED ring lights the work without the shadow of a trigger-mounted light.
  • Single-handed bit insertion speeds up bit changes.
  • The 5-year tool warranty runs longer than most other major brands.

Weaknesses

  • The bare tool lists at $149 at most retailers, and some owners call it overpriced.
  • It is louder than the M12 Fuel Surge hydraulic driver, which owners note for its quiet running.
  • No battery or charger is included, so new buyers pay for both.
  • The glass-filled nylon housing reads as “cheap plastic” to some owners.
  • One reviewer reported poor Milwaukee service; the company pointed them to its social media contact.
  • Milwaukee publishes no IP rating or runtime figures, and no instrumented torque test exists.

Power and size

Milwaukee rates the 3453-20 at up to 1,500 in-lbs of torque and 3,600 RPM in its highest mode, with a 5-inch head and a 1.6–2 lb weight. Pro Tool Reviews tested it on ledger screws and large lag bolts and found it “performs quickly and confidently” and “punches above its weight class”. That review puts the Gen 3 about 10% faster and 200 in-lbs stronger than the Gen 2 it replaced, with the impact rate unchanged at 4,000 IPM. The torque figure is Milwaukee’s rating; Pro Tool Reviews confirms it in practice but does not publish instrumented measurements, so treat the number as a manufacturer claim.

Reddit owners keep coming back to the power-to-size ratio. In r/MilwaukeeTool and r/Carpentry threads, several say it beats many mid-range 18V drivers, and one calls it the most versatile tool Milwaukee makes. Owners doing HVAC and plumbing work rate it for reaching into tight spaces. The trade-off is that it is a 12V tool, so heavy framing still wants a full-size 18V driver.

Noise and the Surge alternative

The 3453 is a conventional impact driver, and it sounds like one. An owner who runs both this and the M12 Fuel Surge hydraulic driver says the Surge has its perks beyond being quiet. Pro Tool Reviews notes the Surge runs 7–13 decibels quieter than other 12V impact drivers, but it makes about 450 in-lbs of torque against the 3453’s 1,500 and drives more slowly. If you work near customers or in quiet spaces, the Surge is the calmer tool; if you want maximum speed and power in a small body, this is the one.

Price and running costs

The bare tool lists at $149 at Northern Tool, Ace Hardware, Acme Tools, Ohio Power Tool and Supplyhouse, while the kit (3453-22) with two 2.0 Ah batteries, a charger and a bag lists at $199 at Northern Tool and Ohio Power Tool. Pro Tool Reviews listed the bare tool at $139 and the kit at $169 in July 2024, so the street figures have crept up since that review. One Reddit owner reports paying $150 for a combo that bundled a Fuel hammer drill, a 4.0 Ah battery and a free 5.0 Ah high-output pack, and Home Depot showed the one-battery 3453-21 kit at $99 on sale, down from $159.

The real ownership cost is the battery platform. The tool ships bare, so a first-time M12 buyer also needs at least one M12 battery and a charger. If you already run M12 tools, the incremental cost is just the bare tool. The only consumable is bits; the driver itself has no filters or fluids.

Repairs, warranty and upkeep

Milwaukee warrants the tool to the original purchaser for 5 years against defects in material and workmanship, and the battery for 2 years. The warranty covers free repair or replacement and does not cover misuse, normal wear and tear, or repairs made by non-Milwaukee personnel; normal wear parts like chucks and driver bits are excluded. Milwaukee runs a service center network and an eService mail-in repair program. A published parts list and an operator’s manual exist for the tool, which points to some manufacturer-supported repair documentation. No widespread failure modes, recalls or common breakage patterns turned up in the owner threads checked, so reliability looks sound rather than proven over multi-year professional use.

Which model this is

This page covers the Gen 3 Milwaukee M12 FUEL 1/4 in. Hex Impact Driver, model 3453-20, released in mid-2022 to replace the 2553-20 (Gen 2). The original was the 2453-20. It is sold as a bare tool only; if you want batteries, look at the 3453-22 kit. Milwaukee’s overview copy says the M12 system has over 150 solutions while its bullet list says over 125 tools, so the ecosystem count depends on which line you read.
