JET J-4103 2" × 72" Square Wheel Belt Grinder
Are you spending too much time grinding, deburring, and chamfering parts by hand with results that vary from piece to piece?
What if you had a machine built around a flat grinding surface that stays square to the work, so you can move through stock removal, edge cleanup, and contouring without switching setups?
Meet the JET J-4103 2" × 72" Square Wheel Belt Grinder, a US-made belt grinder designed around a flat platen and square front wheel that handles grinding, deburring, and chamfering on a wide range of part shapes and sizes.
With the J-4103, you get a machine that works on internal and external surfaces, cylindrical shapes, and difficult-to-reach areas, all from a single grinder built to a consistent standard.
When your shop demands clean, repeatable results on steel, iron, or aluminum, the J-4103 gives you the surface control to deliver them.
JET J-4103 for Grinding, Deburring, and Contouring Metal Parts
Flat Platen Design Keeps the Grinding Surface Square
The J-4103 uses a flat platen with idler wheels at each end to create a long, flat grinding surface. The front wheel is square to the work rather than crowned, so you get consistent contact across the face of the part. This setup removes the guesswork from flat grinding and keeps results uniform from one piece to the next.
Contact Wheels Reach Cylindrical and Internal Surfaces
The grinder includes a 3" × 2" and a 1-1/2" × 2" diameter contact wheel for working cylindrical shapes and areas that a flat platen cannot reach. These wheels let you grind and finish curved or recessed surfaces without moving to a separate machine. The yoke surface conforms to the shape of the part to maintain even contact and a smooth finish.
Serrated Contact Wheel Handles Heavy Stock Removal
For weld cleanup, casting cleanup, and heavy stock removal, the serrated contact wheel gives you the aggressive cut you need without loading the belt. It clears material quickly so you can move to finishing passes with the flat platen or smooth contact wheels. Having both options on one machine keeps your workflow moving without swapping equipment.
1 HP Motor Runs on Standard Shop Power
The 1 HP motor runs on 115/230V single-phase power, which fits most single-phase shop setups without dedicated wiring. The motor drives a 2" × 72" belt, a common size that is easy to source in a range of grits and materials. This keeps your consumable costs straightforward and your downtime low.
