Performance notes

The Makita 9403 runs on 120-volt corded power drawing 11 amps, delivering a belt speed of 27.33 feet per second. The 13-pound weight indicates a robust full-frame professional design rather than a compact or portable tool. Power source is corded electric, so a suitable circuit with consistent amperage is required for full performance. These specs position the 9403 squarely in the professional and heavy-duty segment of the belt sander market.

What buyers say

The Makita 9403 is one of the most trusted belt sanders in the professional segment, reflected in its 2,886-review base and 4.7-star average. Owners consistently highlight the motor power, build durability and smooth belt tracking as primary strengths. The main reported trade-offs center on the tool's 13-pound weight and its premium price, both of which buyers accept knowingly when selecting a professional-grade machine.
