## At a glance

- The belt head locks at any angle from 0 to 90 degrees, with indexing stops at 0, 45 and 90 degrees.
- The belt table tilts down to 45 degrees for beveled and mitered sanding.
- Precision-ground cast-iron tables have miter slots, and the listing describes them as designed for rigidity.
- Listing claims a 1.5 HP motor and a prewired 115V single-phase setup that can be converted to 230V.

## Pros

- Belt and disc sanding are combined in one machine, with a movable belt head for horizontal, vertical and intermediate positions.
- Tilt-adjustable tables and miter slots support angled work and use of a miter gauge.
- The included abrasive belt and disc are both listed as 60 grit.

## Cons

- At 247 pounds, the listed weight makes this a substantial machine to position or relocate.

## Less suited to

## Customer feedback

Customer feedback describes the machine as well built, with straightforward assembly, while reports about dust collection and mobility are mixed. Some customers say it runs without vibration, while others find it difficult to move. Those differences matter for a heavy stationary machine, especially if dust handling and frequent repositioning are priorities. Aggregate ratings lean positive but include lower ratings, so they do not establish how it will perform in a particular shop.
- Positive themes: Customers describe heavy-duty construction and straightforward assembly.
- Mixed feedback: Feedback on dust collection is mixed, with some saying it helps substantially and others reporting that some dust remains.
- Mixed feedback: Mobility feedback differs. Some report vibration-free operation, while others say moving the machine is difficult.
