A front grip and balanced weight distribution improve handling during prolonged use, while the long 16.4-foot cord adds reach and flexibility on bigger jobs. The dust collection system minimizes mess in the shop, and the included dust bag helps you stay prepared for cleanup between passes. An optional sanding shoe is available if you need precise depth control for fine work.
