Overview
The Makita 9403 is a corded electric belt sander running on a 120 volt, 11 amp motor, with a belt speed of 27.33 feet per second and a tool weight of 13 pounds. It is built for stock removal and surface leveling rather than light finish sanding.
An 11 amp motor paired with a belt speed north of 27 feet per second puts this at the higher-output end of belt sanders, the kind contractors reach for on flooring and framing lumber rather than furniture touch-up. At 13 pounds it is heavier than a palm or orbital sander, and that mass helps keep the belt tracking flat under load.

Who it's for
Contractors and serious woodworkers sanding floors, decks or large panels who need fast material removal. Not the right tool for fine finish work or anyone wanting a lightweight, one-handed sander.
Pros and cons
- 11 amp motor for fast stock removal
- Corded power for unlimited runtime
- 13 pound body helps the belt track flat
- Less suited to fine finish work
- Corded design limits reach compared to battery tools
Performance notes
The 11 amp motor and 27.33 feet per second belt speed indicate a sander tuned for fast material removal on wood and similar surfaces. Corded power means no battery runtime to manage on longer jobs, and the 13 pound body adds the downward mass that helps a belt sander cut evenly instead of chattering.
