Utilising a POWERSTATE Brushless Motor and a best in class 22mm stroke length, the M18 FUEL HACKZALL cuts up faster. The compact, one-handed design provides superior control and the ability to make cuts in tight spaces. The dual gear counter balance mechanism provides lower vibration than traditional reciprocating saws, resulting in faster cut-starts in metal and reduced user fatigue. REDLINK PLUS Intelligence ensures optimised performance and protects your investment from overload, overheating, and over-discharge. The M18 REDLITHIUM-ION 5.0Ah Battery Pack provides more work per charge and more work over the life of the pack than competitive batteries. A rubber seal and weep holes provide superior protection against water and debris.
