S6MW Features & Benefits

Why the Kalamazoo S6MW Works Hard for Your Shop

The Kalamazoo S6MW 6 x 48 inch industrial wet belt sander keeps parts cool, belts sharp, and your shop moving every shift.

Built-In Flood Coolant

The S6MW runs a 10-gallon flood coolant system with an adjustable nozzle and flow control ball valve, so you sand longer without stopping to let parts cool down.

Strong 3 HP Motor

A 3 HP motor at 2,800 SFPM drives this metal finishing sander hard through steel, aluminum, titanium, and other alloys so your shop removes material fast and clean.

Industrial Metal Polishing Machine

Use the S6MW as an industrial metal polishing machine to push parts from rough to high-gloss — wet sanding keeps the surface cool and clean the whole time.

Ready for Metallurgical Sample Preparation

Labs and production shops rely on the S6MW for metallurgical sample preparation because wet sanding delivers a flat, clean surface that holds up under close inspection.

Versatile Metal Polishing Machine

As a metal polishing machine, the S6MW handles deburring, sharpening, shaping, and polishing on metal, glass, stone, and plastic — all from one heavy-duty machine on your floor.

Made in the USA

The S6MW is built in Kalamazoo, Michigan with a cast iron frame and base, full steel OSHA guard, and a one-year parts warranty so your shop stays up and running.

S6MW Applications

Top Uses for the S6MW 6 x 48 Inch Industrial Wet Belt Sander

If your shop needs to sand wet, the S6MW keeps parts cool, belts cutting, and your crew moving — shift after shift.

  • 1
    Metallurgical Sample Preparation

    Labs and QC teams count on the S6MW for metallurgical sample preparation. Steady water flow holds the surface flat and cool so the sample stays true under inspection — no heat scale, no distortion.

  • 2
    Metal Finishing on Steel, Aluminum, and Titanium

    Use the S6MW as a metal finishing sander and push through hard alloys without burning the part or glazing the belt. The 3 HP motor drives the belt at 2,800 SFPM so your shop removes material fast and moves on.

  • 3
    High-Gloss Metal Polishing

    Run the S6MW as an industrial metal polishing machine and take parts from rough to mirror finish in one setup. Wet sanding keeps the surface cool and clean the whole way through so your finish holds up.

  • 4
    Deburring and Edge Work on Hard Alloys

    Hard metals generate serious heat. The S6MW handles stainless, titanium, and hardened steel as a metal polishing machine that keeps edges sharp and belts lasting — without stopping to let parts cool down.

  • 5
    Glass, Stone, and Plastic Finishing

    The S6MW does more than metal. Shops use it to grind and polish glass edges, shape stone, and finish plastic parts without melting or cracking — because wet sanding keeps temperatures low from the first pass to the last.
