M12™ HACKZALL® Recip Saw

The Milwaukee M12 HACKZALL Recip Saw is a compact cordless reciprocating saw designed for one-handed cutting in tight spaces. Powered by the Milwaukee M12™ lithium-ion battery system, it provides strong cutting performance while remaining lightweight and easy to control for overhead or confined work.

The tool features a powerful motor that delivers 0–3,000 strokes per minute with a 1/2-inch stroke length, allowing users to cut through materials such as wood, drywall, PVC, and thin metal quickly and efficiently. Its compact design—about 11 inches long and roughly 2.6 lb—makes it ideal for jobs where a full-size reciprocating saw would be difficult to use.

A variable-speed trigger provides precise cutting control, while the QUIK-LOK® keyless blade clamp enables fast blade changes without additional tools. The saw is compatible with both HACKZALL® and SAWZALL® style blades, giving users flexibility depending on the material being cut.

Built-in features like an LED work light and battery fuel gauge help improve visibility and allow users to monitor remaining battery life during operation.
