Overview
A remodeler or plumber who cuts through pipe and studs in tight spaces is the buyer for this Milwaukee reciprocating saw. It is brushless, runs on eighteen volts and arrives without a battery.
A cordless saw with a brushless motor cuts away from an outlet and stays fairly light. The limitation is the bare tool format and the figures, which show a speed with no unit and a wattage that does not match typical ratings.
Who it's for
Demolition, plumbing and metal cutting where a cord gets in the way suit this tool. Buyers new to the platform should add a battery to the plan.
Pros and cons
- Bare tool for battery owners
- Metal cutting recommendation
- Battery sold separately
- Speed unit missing
- Wattage figure looks inconsistent
Performance notes
A reciprocating motion drives the blade back and forth, and brushless motors hold speed under load. Cutting rate depends on the blade, which here is described by tooth count.
