Key Features & Benefits
- 940W motor driving a 100mm belt at 380 m/min — removes material fast on large flat surfaces and rough stock.
- Flush-to-wall design — lets the belt sand right up against walls, skirtings and adjacent edges.
- 100 x 610mm belt size — uses a widely available belt format for grits from coarse stripping to finer levelling.
- Dust bag and carbon plate — capture debris and protect the platen for cleaner, longer service.
- Wide sanding footprint — keeps work flat and reduces the risk of dishing on broad surfaces.
- Front roller access — makes belt changes and tracking adjustment straightforward.
When to Use This Belt Sander
Choose the M9400B when you need to remove material fast over large flat areas — levelling timber, stripping paint or rust, and prepping floors and decking. Its flush-to-wall design suits work into corners and against skirtings. For benchtop detail use a 9 x 533mm file sander like the 9031; for the most powerful flat sanding the 1200W 9403 leads the range.
Pro Tip: Keep the M9400B moving with the grain and let its weight do the work — a 100mm belt at 380 m/min cuts fast, so dwelling in one spot or pressing down dishes the surface and burns the belt. Start with the sander already moving before it lands on the work.
