This steel grinder is built for tough jobs. It has a 5 HP 3PH motor and a high‑speed belt that runs about 6 900 SFPM. The machine’s rugged construction and built‑in dust collector mean it’s well suited for demanding shops.

Yes! The KS390HV can handle steel, stainless steel, iron and cast‑iron parts. It’s designed for custom sheet metal fabrication projects and the day‑to‑day needs of fabrication companies working with forged or cast parts.

Grinding creates dust. The KS390HV’s integrated collector pulls dust away at the source, keeping the workspace cleaner and safer. Clean air improves worker comfort, reduces cleanup time and supports a healthier shop environment.

Absolutely. A quick‑change door lets you swap belts fast, and spring tensioning makes adjustments easy. The magnetic on/off switch and heavy‑duty design mean less downtime and more focus on production.

After cutting and forming metal sheets, parts often need a clean finish. Grinding uses an abrasive belt to remove small chips and smooth surfaces. A tool like the KS390HV can quickly deburr edges and clean up welds, helping you deliver precise, professional results.

Plasma cutting delivers fast, precise cuts in steel, stainless, and other metals. After cutting, a belt grinder finishes edges, removes burrs, and smooths surfaces so parts meet your exact specifications.

The grinder runs on 230 V or 460 V (three‑phase) power.  Its 5 HP motor drives the belt at about 6 900 SFPM, providing plenty of speed for aggressive stock removal or fine finishing.

Yes. The KS390HV is designed for busy industrial environments, yet many small and mid‑sized shops appreciate its reliability. It helps solve production problems by speeding up grinding jobs, keeping the workspace cleaner and delivering consistent quality.

You can add a variable frequency drive for speed control and choose from different grit belts.  Replacement filters for the dust collector are also available. These options let you tailor the machine to your shop’s specific tasks.

The KS390HV is made in the USA. Shipping dimensions are roughly 39″ L × 59″ W × 54″ H, and it weighs around 500 lbs.
