OVERVIEW

The Welder's Choice for Stainless Steel

When you are fabricating stainless steel, you need a wheel that cuts fast and runs cool. The Pferd 5" x .040" SG-INOX Type 27 Cut-Off Wheel is built exactly for that purpose. Known in the trade for its exceptional bite, the SG-INOX formula uses premium aluminum oxide grain that slices through stainless and mild steel with minimal effort. The ultra-thin .040" profile means you aren't wasting time turning good metal into dust—you get a precise, narrow kerf that requires very little cleanup.

The Type 27 depressed center shape is a favorite among pipe welders and fabricators because it allows the locking nut to sit recessed within the wheel. This geometry enables you to get the wheel flush against a surface, perfect for trimming off tack welds, cutting off bolts, or working in tight corners where a flat Type 1 wheel would get hung up. Despite its thinness, the R-grade bond hardness ensures the wheel holds up under the rigors of daily shop use, giving you more cuts per wheel and fewer changeovers.

Contamination-Free Cutting

One of the biggest headaches in stainless fabrication is cross-contamination leading to rust. Pferd's INOX rating guarantees this wheel is free from iron, sulfur, and chlorine additives. You can cut with confidence knowing you aren't embedding contaminants into your pristine stainless welds. Whether you are in the field or in the shop, this 5-inch zipcut is a versatile, reliable tool that helps you get the job done right the first time.

FAQ

Type 1 wheels are flat, while Type 27 wheels have a depressed center. The depressed center allows the mounting nut to be recessed, enabling flush cutting against a surface and providing greater rigidity.

No, this is a .040" thick cut-off wheel designed for cutting only. Using it for side grinding is dangerous and can cause the wheel to shatter. Use a Type 27 grinding disc (typically 1/4" thick) for grinding.

Yes, the SG-INOX designation means it is manufactured without iron, sulfur, or chlorine fillers, preventing contamination and corrosion on stainless steel.

This wheel fits a standard 5-inch angle grinder with a 7/8-inch arbor.

The ultra-thin .040" profile removes less material, resulting in faster cuts, less heat buildup, and minimal burr formation compared to thicker 1/8" or 1/16" wheels.

While it can cut aluminum, it is not optimized for it. Aluminum is soft and may clog (load) the abrasive grain. A wheel specifically designed for non-ferrous metals is recommended for aluminum.

Always check the label on the wheel itself, but standard 5-inch abrasive wheels are typically rated for a maximum of 12,200 RPM.

You should always use the appropriate safety guard designed for cut-off wheels on your angle grinder to ensure operator safety in case of breakage.
