## Product: Makita 9404 Belt Sander
**Brand:** Makita

## Pros
- Excels at heavy-duty sanding tasks like floor refinishing and cabinet restoration, efficiently stripping old finishes and revealing wood grain.
- Powerful 8.8-Amp motor maintains speed under heavy pressure without bogging or slipping.
- Variable speed control helps prevent bogging and allows for fine adjustments suitable for different wood types and grits.
- Belt tracking works flawlessly across multiple grits (36 to 120), providing straight, even sanding.
- Well-balanced, sturdy design allows comfortable one-handed use and stable stationary operation when flipped upside down.
- Effective dust collection with included cloth dust bag, especially when attached to a shop vac, significantly reduces airborne dust.
- Wide 4-inch sanding belt covers large surface areas quickly and evenly.
- Ergonomic features like a trigger lock, quick belt change lever, and belt tracking wheel enhance user convenience.
- Durable, heavy-duty construction comparable to high-quality Japanese automotive engineering ensures long-lasting performance.
- Can be securely attached to custom supports using threaded holes for precise stationary sanding work.

## Cons
- Heavy weight (8.8 lbs) can make prolonged overhead or vertical sanding tiring and potentially unsafe.
- Dust bag fills quickly, especially when using coarse grits; a wet vacuum is recommended for optimal dust control.
- Not ideal for tight corners or intricate detail work; best suited for open, flat surfaces before trim installation.
- Runs warm during extended use, which might necessitate breaks to avoid overheating.
- Lower speeds with coarse grits may reduce sanding power somewhat.
- Requires gloves and caution during stationary use due to risk of catching fingers or nails.
- Initial physical effort can be demanding, comparable to a first-time workout.
- Although relatively quiet, ear protection is advised during long periods of use or when vacuuming dust.

## Bottom Line

The Makita 9404 is a powerhouse 8.8-Amp belt sander built for serious woodworkers who want fast, smooth results on large, flat surfaces like hardwood floors or tabletops. Its expertly designed dust collection and variable speed make it versatile, though it’s best paired with a shop vac for cleaner workspaces. Heavy and sturdy, it’s not the gentlest tool for extended overhead use or tight corners, but for bulk material removal and refinishing jobs, it’s a reliable champ. If corner sanding or lighter, handheld finesse is vital, consider complementing it with an orbital sander or specialized edge tool. Overall, this sander earns top marks for power, precision, and durability in its class.
