Powermatic 31A for Versatile Belt and Disc Sanding
Articulating Belt Head Expands Sanding Positions
The belt head adjusts from vertical to horizontal and anywhere in between to match the task. An indexing pin with positive stops at 0°, 45°, and 90° allows quick, repeatable positioning. The locking system lets you fine-tune angles beyond preset stops. This flexibility supports edge work, face sanding, and contour shaping without changing machines.
Cast Iron Tables Support Accurate Sanding
Precision-ground cast iron tables provide a stable reference surface for both belt and disc sanding. Integrated miter slots allow controlled angle and bevel sanding. The rigidity of the tables reduces deflection during use. This helps maintain consistent contact and improves overall accuracy.
Crowned Drums and Platen Maintain Belt Tracking
The solid cast iron platen supports the belt evenly during operation. Crowned aluminum drums help keep the belt centered and tracking smoothly. This reduces belt drift and uneven wear. Consistent tracking leads to more predictable sanding results.
Dual Dust Ports Improve Abrasive Life
Separate dust ports collect debris from both the belt and disc sanding areas. This helps keep abrasive surfaces cleaner during use. Cleaner operation reduces heat buildup and extends belt and disc life. It also supports a cleaner working environment.
