The DEWALT DCMCS574 XR FlexVolt Chainsaw features an energy-efficient brushless motor for extended run times and requires less maintenance than a petrol chainsaw. It includes an auto-oiling system for chain lubrication and a tooled chain tensioning system designed to professional specifications for reliable tensioning during use. The chain speed is optimized for improved torque, and a chain brake stops the chain in under one second if triggered. Specifications include a 45cm bar length, 13.5m/s chain speed, 3/8in chain pitch, and a weight of 5.0kg. It is part of the FlexVolt battery platform, offering cordless convenience and power.
