Vintage Sears Craftsman Combination Belt/Disc Sander Guide
Introduction
For decades, the Craftsman combination belt and disc sander was one of the most popular finishing machines sold by Sears. Combining the versatility of a belt sander with the precision of a disc sander, these machines became staples of home shops, schools, and small woodworking businesses. Today, vintage Craftsman belt/disc sanders remain collectible, valued for their rugged cast-iron construction, affordability, and nostalgic appeal.
History of Craftsman Combination Sanders
As with other Craftsman woodworking machines, Sears contracted with outside manufacturers to produce belt/disc sanders under the Craftsman brand:
- King-Seeley Corp. (1930s–50s): Produced early cast-iron sanding machines, including bench-top units with small belts and discs.
- Atlas Press Co. (103 series, 1940s–50s): Manufactured compact combo sanders, often with 4” x 36” belts and 9” discs.
- Emerson Electric (113 series, 1950s–70s): Supplied the most widely sold 6” x 48” belt / 9” or 12” disc sanders. These became the classic Craftsman combination machines.
- Later Models (1970s–80s): Lightweight benchtop units with aluminum frames, often smaller (4” x 36” belt / 6” disc), geared toward hobbyists.
Combination sanders became one of the most enduring machines in the Craftsman lineup, remaining popular through the 1980s.
