Overview
The Milwaukee 2621-20 is a battery powered reciprocating saw that runs at up to 3000 strokes per minute for demolition and cutting jobs. It weighs 7.7 pounds and is sold as a bare tool, meaning the battery and charger are purchased separately.
This is a bare tool listing, so the 2621-20 model number refers to the saw body only. Milwaukee's M18 reciprocating saws are built for job site demolition, remodeling, and plumbing or electrical rough-in work where cutting through mixed materials matters more than finesse. The 6.3 inch capacity figure in the spec data most likely refers to stroke or cutting capacity rather than the saw's overall size.
- Up to 3000 strokes per minute
- Runs on Milwaukee's M18 battery platform
- 7.7 pound bare tool weight
- 6.3 inch cutting capacity
Who it's for
Fits tradespeople and serious DIYers who already own Milwaukee M18 batteries and want a dedicated demolition saw. Less useful to someone starting from zero, since the battery and charger add to the real cost.
Strengths and trade-offs
Drawn from this product's published specifications.
- 3000 RPM for fast cutting and demolition
- Cordless freedom on the M18 battery platform
- Metal housing built for repeated heavy use
- Sold as bare tool, no battery or charger included
- At 7.7 pounds it's heavier than compact reciprocating saws
Performance notes
At up to 3000 strokes per minute, this saw is geared toward fast material removal in demolition and rough cutting rather than precision work. The all metal gear housing referenced in the spec data suggests a build meant to handle repeated heavy use rather than occasional light jobs.
