ASIN: B005HPUZWQModel: J-4210KCategory: Combination Disc & Belt Sanders
Overview
This is a benchtop combination sander pairing a 6 x 48 inch belt with a 10 inch disc, powered by a 1 HP motor that runs on 115V or 230V single phase. It suits a home shop or small commercial shop needing one machine for both flat stock and curved edge sanding.
JET builds this as a shared table combo unit, so the belt and disc sit on one work surface and share one motor, a common layout for shops with limited floor space. The dual voltage motor gives some wiring flexibility without a transformer. No detailed spec sheet or review data came through with this listing, so exact table tilt range and dust port size are not confirmed here.
- 6 x 48 inch sanding belt
- 10 inch sanding disc
- 1 HP motor
- 115V/230V single phase
Who it's for
Fits a woodworker or metal hobbyist who wants belt sanding for long straight edges and disc sanding for curves in one footprint. Less suited to a production shop running the machine all day, where a 1 HP shared motor becomes a bottleneck.
Pros and cons
- Combines belt and disc sanding in one machine
- Dual voltage motor adapts to 115V or 230V circuits
- Compact footprint fits a home or small shop bench
- 1 HP motor is modest for production work
- Shared table means switching setups between belt and disc
Performance notes
The 1 HP motor drives both the belt and disc from a single shaft, so only one function runs at a time. Dual voltage wiring (115V/230V single phase) lets the same motor run on standard shop power or a 230V circuit for more headroom, useful if the shop already has 230V drops.
