Milwaukee M12™ 12-Volt reciprocating saws, known as a HACKZALL™, are a one of a kind cutting tool designed to perform in a similar fashion to larger recip saws while allowing the user to hold and operate the tool using only one hand. The M12 FUEL™ Sub Compact HACKZALL™ features a brushless POWERSTATE™ motor for up to 6x longer motor life and up to 70% faster cutting in certain applications. The M12CHZ HACKZALL™ also features a counter balance mechanism which lowers vibration to 6.5 m/s² allowing the operator to work safely for longer periods of time reducing fatigue.
