Summary
A compact brushed-motor 18 V impact driver for shops already on Milwaukee’s M18 battery platform, rated at 2,750 RPM, 3,450 IPM and 1,500 in-lbs of fastening torque. Check whether you already own an M18 battery and charger — the tool ships alone, and no independent test has verified those numbers.
Strengths
- 1,500 in-lbs of fastening torque and 3,450 IPM in a compact body.
- REDLINK Intelligence protects the tool, battery and charger from overload.
- Five-year tool warranty with no registration required.
- All-metal reversible belt clip and an LED work light are included.
- Published parts lists and a nationwide service network support long-term repairs.
- Milwaukee positions it as the most powerful 1/4-inch hex compact impact driver in its class.
Weaknesses
- Sold tool-only: no battery, charger or case, so the real cost is higher for anyone not already on M18.
- No instrumented independent test of this exact model exists; the torque and speed figures are manufacturer ratings.
- It is a brushed, non-FUEL design competing against newer compact drivers.
- Dimensions, weight and sound ratings are not published on the manufacturer page.
- Normal-wear parts — chucks, brushes, seals — are excluded from the warranty.
- Battery packs carry their own warranty terms, not the tool’s five years.

Full research notes and sources
Tool-only means battery and charger extra
The “-20” suffix in Milwaukee’s nomenclature means tool-only: the box holds the driver and a belt clip, nothing else. If you already own M18 packs, the sticker price is the whole story; if not, a battery and charger add real cost before the tool turns a screw. Battery packs also carry separate warranty terms — two or three years depending on the catalog number — not the tool’s five years.
Warranty, parts and service
Milwaukee warrants the tool for five years to the original purchaser against defects in materials and workmanship, with no registration required; the date code is used when there is no proof of purchase. Normal-wear parts are excluded — chucks, brushes, cords, o-rings, seals, bumpers, driver blades, pistons, strikers and lifters among them. Milwaukee publishes parts lists for this model (54-26-2500 through 54-26-2503) and runs eService mail-in plus authorized service centers at 1.800.SAWDUST. The manual instructs service by qualified personnel using identical replacement parts.
What the specs do and don’t tell you
Every performance number on this tool — 2,750 RPM, 3,450 IPM, 1,500 in-lbs — comes from Milwaukee. The operator’s manual confirms the no-load figures (0-2,750 RPM, 0-3,450 IPM) and 18 V DC operation, but no established outlet has published an instrumented test of the exact 2656-20; a search of Pro Tool Reviews returned only generic Milwaukee buying guides. Treat the torque claim as a manufacturer rating until someone measures it. One trap: the manual’s spec table is shared with the 2657-20, 2658-20 and 2659-20, and the 2657-20 is a two-speed tool rated 0-2,450/3,350 RPM-IPM — only the 2656-20 row applies here. Milwaukee calls the 2656-20 the most powerful 1/4-inch hex compact impact driver in its class; that is marketing language, not a test result.
Is it worth it?
For a shop already running M18 batteries, the math is simple: you are buying the tool alone, and the five-year warranty plus published parts lists make it a reasonable long-term keeper. For a buyer new to the platform, the battery and charger spend lands on top of the sticker, and newer compact drivers compete on price. The research pass found no retail pricing from major stores, so check current prices before deciding. If you need verified torque, note that no independent measurement exists.
