With its 11 AMP motor and electronic speed control, it powers through stock removal at an impressive 1,640 ft./min., making quick work of rough lumber, reclaimed wood, or weathered decking common in US backyards.

Key features shine in real-world use: the whisper-quiet 84dB noise level allows focused work without constant ear protection, while the innovative low-profile design enables flush sanding against walls and edges—ideal for refinishing interior rooms or tight garage spaces.
