Hackzall M12 CHZ-402C 12 V Li-Ion 2 x 4.0 Ah Cordless Reciprocating Saw (4933446950) Description: Milwaukee® designed and built brushless POWERSTATE motor delivers up to 6 times longer motor life and 70% faster cutting efficiency with Smart Control REDLINK PLUS - State-of-the-art digital tool and battery overload protection for exceptionally better tool performance under load. REDLITHIUM-ION battery provides up to 20% more power, up to 2x longer run time, up to 2x longer durability and operates down to -20 °C ( (compared to other lithium-ion technologies) Individual cell monitoring optimises tool run time and ensures long battery life. FIXTEC saw blade clamp - quick and easy tool-free saw blade change. Counterbalance mechanism reduces vibrations to 6.5 m/s², allowing the operator to work safely and without fatigue, even over long periods of time. The gearbox prevents water and dirt from entering the housing. LED lighting - illuminates the cutting line in low light conditions. Compact unit design and light weight allow users to work in confined spaces.
