9403 4" × 24" Belt Sander (Corded)
Last verified by the Lifetime Picks Editorial Team
Why we picked it
4×24" belt size — more material removal per stroke than 3-inch
Makita's 9403 is the 4×24 belt sander r/woodworking, r/turning, and r/Construction surface as the consensus 'real' belt sander — heavy (13 lbs), high-torque (11-amp motor), and quiet (~84 dB) by belt sander standards. The 4-inch belt width covers more surface area per stroke than 3-inch competitors; the 24-inch belt length matches the standard commercial belt size for cheap bulk replacement. The motor is positioned to keep the belt parallel to the workpiece without operator wrist-correction. r/woodworking treats this Makita as the BIFL belt sander — it survives the daily 8-hour use that destroys consumer belt sanders. Replaceable brushes from Makita for indefinite motor service.
