Cleaner work environment: Detachable dust hood with dual outlets connects to industrial vacuums to capture dust at the source. Builtin LED lighting improves visibility in lowlight areas. Easier handling and less fatigue: Slipresistant grip, integrated auxiliary wheels, and a selflocking feature support steady operation. An extension rod is available as an optional configuration to allow upright use.
