JET J-4421 20" Industrial Disc Sander
Are your finishing and stock removal tasks slowing down production because your equipment can't keep pace with the demands of serious shop work?
What if you had a machine with a large sanding surface, a flexible tilting table, and the power to handle heavy material removal without losing a step?
Meet the JET J-4421 20" Industrial Disc Sander, a heavy-duty disc sander built for shops that need consistent results on large workpieces day after day.
With the J-4421, you get a 20" disc surface, a precision rack and gear table system, a rigid column and heavy-duty base, and a low voltage protection switch that keeps your operation running safely.
When your sander can handle the work without slowing you down, you spend less time on setbacks and more time on results that meet your standard.
JET J-4421 for Heavy Stock Removal and Surface Finishing
20" Disc Surface Handles Large Workpieces
The 20" abrasive disc gives you a wide working surface that handles large parts without repositioning. The tilting table lowers completely below the disc, so you can use the full disc surface when the work calls for it. That range of access keeps large and awkward workpieces manageable.
Rack and Gear Table System Speeds Setup
The precision table raiser uses a rack and pinion gear system controlled by a crank that moves the table smoothly and holds position without slipping. The table assembly is counterbalanced to make raising and lowering easier and to extend the service life of the lifting components. Adjustments are direct and repeatable.
Tilting Table Adds Versatility for Angled Work
The table tilts 45 degrees downward and 15 degrees upward with a positive lock on the worm-and-sector gear system. A built-in protractor lets you set angles quickly, and a machinist's protractor can be used when high-precision angles are required. The miter gauge slot adds a second axis for grinding compound angles.
Rigid Column and Heavy-Duty Base Maintain Stability
The rigid column and heavy-duty base keep the machine stable under load. A wrap-over guard covers the disc edge, and the low voltage protection switch prevents unintended restarts after a power interruption — an important safeguard in any production environment.
