When choosing between the 6 x 48 vs 4 x 36 disc and belt sander, you face a clear trade-off in capacity and size. Both machines share a 3/4 HP motor and benchtop configuration, making them solid tools for woodworking. The primary difference lies in the belt dimensions and disc diameter. One unit offers a larger 6-inch belt and 9-inch disc, while the other provides a more compact 4-inch belt and 6-inch disc. Your choice depends on the scale of your projects and your workspace constraints.

Belt Size and Capacity Comparison
Belt Width
The JET JSG-96 features a 6-inch wide belt, while the Woodskil model uses a 4-inch wide belt. A wider belt allows you to sand broader surfaces in fewer passes, which improves efficiency for larger workpieces. The JET design accommodates this full 6-inch width with a specially designed belt guard that ensures safety without restricting the working area. The Woodskil unit is limited to the narrower 4-inch width. If you frequently handle wide boards or panels, the extra width on the JET provides a clear operational advantage. The Woodskil is better suited for narrower stock or detailed edge work where a smaller belt offers more control.
Belt Length
Belt length determines how much abrasive material is available before replacement and affects heat dissipation. The JET JSG-96 utilizes a 48-inch belt, whereas the Woodskil sander uses a 36-inch belt. The longer 48-inch belt on the JET runs cooler and lasts longer because the abrasive grains have more distance to travel before returning to the contact point. This reduces heat buildup, which extends the life of both the belt and the graphite-covered steel platen. The shorter 36-inch belt on the Woodskil cycles faster, which may lead to quicker wear under heavy use. For extended sanding sessions, the JET offers superior durability.
Motor Power
Both the JET JSG-96 and the Woodskil sander are equipped with 3/4 HP motors. This shared specification means both machines deliver similar raw power output for driving the belts and discs. The JET operates on 115V single-phase power, which is standard for benchtop tools. The Woodskil data lists 4.3A amperage, which correlates to the 3/4 HP rating. Since the motor power is identical, neither machine holds an advantage in terms of torque or general sanding capability derived from the motor itself. You can expect comparable performance in cutting through wood stock with both units, assuming similar load conditions.
Disc Diameter
The size of the disc sander affects the surface area available for flat sanding and shaping. The JET JSG-96 comes with a 9-inch disc, providing a larger working surface for broader tasks. The Woodskil model features a 6-inch disc. The larger 9-inch disc on the JET allows you to sand wider pieces of wood flat without needing to reposition the workpiece as often. It also offers more room for using the disc for shaping curves or edges. The 6-inch disc on the Woodskil is adequate for smaller projects but limits the width of material you can sand flat in one pass. The JET offers greater versatility for larger stock.
Table Adjustability
Both sanders offer adjustable tables for angled work, but the range and mechanism differ. The JET JSG-96 has a large cast iron table with preset stops at 90 degrees and 45 degrees, allowing for precise vertical, horizontal, or intermediate positioning. The Woodskil sander features an adjustable belt tilt range from 0 to 90 degrees and a work table that tilts from 0 to 45 degrees with a miter gauge. The JET’s cast iron construction provides a heavier, more stable surface that resists vibration during use. The Woodskil offers flexible positioning but uses a lighter construction. For stability and precision, the JET’s cast iron table is superior.
Which sander fits your workshop needs?
Shop owners with limited floor space
The Woodskil model weighs 25 pounds and measures 15.6 inches in height. Its compact footprint allows you to store it easily on a workbench or shelf. You gain a versatile 4x36 inch belt and 6 inch disc without sacrificing significant workspace. This size is ideal for small projects or tight corners.
Users sanding wide boards frequently
The JET JSG-96 features a 6-inch wide belt, allowing you to sand broader surfaces in fewer passes. The 9-inch disc also handles larger diameters. With a 91-pound cast iron table, you get stability during heavy use. The 3/4 HP motor drives the wider belt effectively for efficient material removal.
Woodworkers needing precise angle adjustments
The JET model includes preset stops at 90 and 45 degrees for the table. You can use the belt sander vertically or horizontally with ease. The cast iron table provides a solid, flat surface for accurate cuts. This precision helps you maintain consistent angles for joinery and detailed woodworking projects.
Users prioritizing dust extraction
The Woodskil sander offers double dust exhaust ports for the disc and belt. This separate system helps you manage debris more effectively. You can connect hoses to both areas to keep your workspace cleaner. The dual ports are a practical feature for maintaining air quality during extended sanding sessions.
