The M18 FUEL Hackzall kit is the fastest‑cutting, most powerful one‑handed reciprocating saw. A POWERSTATE brushless motor and 7/8‑in. stroke length provide up to 50 % faster cuts than competitors, while a dual‑gear counter‑balance mechanism reduces vibration by up to 4× for smoother control. The compact design allows one‑handed use in tight spaces, and REDLINK Plus electronics protect against overload. The saw is sealed with rubber and weep holes to keep debris out and includes a battery and charger.
