The KS490V is a production belt grinder that works great as a grinding station in busy metal manufacturing. In a fabrication shop, it helps operators clean up parts faster, keep finishes consistent, and cut down on dust during sheet metal processing. It’s a strong fit for shops offering manufacturing services because it handles daily “prep work” that keeps jobs moving—before welding, painting, assembly, or final inspection.

Common KS490V applications:

  • Deburr sharp edges on brackets, panels, and cut parts during sheet metal processing.
  • Remove slag and clean up welds for better-looking work in a fabrication shop.
  • Bevel edges before welding to improve fit-up in metal manufacturing.
  • Square up ends, round corners, and smooth flat surfaces for repeatable part quality.
  • Do aggressive grinding and heavy material removal when parts come in rough.
  • Contour and shape parts using the contact wheel for curves and profiles.
  • Sharpen tools and touch up shop items as needed at your grinding station.
  • Help keep the work area cleaner with the built-in vacuum—useful for manufacturing services that run all day.

It’s a 4″ x 90″ belt grinder made to remove metal fast and help control dust with its vacuum base. It’s a solid choice when you need a reliable grinding station that can handle daily shop work.

It’s best for teams doing metal manufacturing, a busy fabrication shop, or companies that offer manufacturing services and need clean, repeatable grinding results.

Use it for deburring, beveling, smoothing welds, cleaning up cut edges, rounding corners, and general part finishing. It’s especially helpful when you’re doing sheet metal processing and want parts that are safer to handle and ready for the next step.

It helps pull grinding dust and debris down into the base while you work. That means less mess around your grinding station and a cleaner area for finishing.

It uses a 4″ x 90″ abrasive belt, which is a common size for production grinding and finishing work.

It’s designed for quick belt changes and easy tracking, which is important when a fabrication shop is switching between grits during the day.

Variable speed is optional. If your work changes a lot—like mixing heavy grinding with lighter finishing—variable speed can be a nice upgrade for metal manufacturing and sheet metal processing jobs.

Make sure you have the right power available, enough floor space, and a plan for the belts you’ll use most (coarse for fast removal, finer for finishing). That way your grinding station is ready on day one.
