Forney 71840 Type 1 Cut-off Wheel 3x1/16 in 1/4 Arbor

Product Description

The FORNEY INDUSTRIES INC 71840 is a Type 1 aluminum oxide cut-off wheel engineered for use on die grinders and air grinders. Measuring 3 inches in diameter with a 1/16 inch thickness and a 1/4 inch arbor bore, this wheel is purpose-built for ferrous metal cutting applications. The aluminum oxide abrasive delivers consistent material removal on steel and iron-based stock. It is a standard unit-of-measure item sold individually within a package quantity of 100 per case, making it well-suited for shops and tradespeople who go through wheels at volume.

This cut-off wheel is designed for die grinders and air grinders only — not for use on angle grinders or bench grinders. Typical applications include metal cutting, metal abrasion, body work, metal fabrication, and general repair work on ferrous materials. It is used in automotive body shops, metal fabrication facilities, and general trade environments where tight-clearance cutting on pipe, rod, and sheet stock is routine work for HVAC, plumbing, and fabrication professionals.

Installation Notes

Installation of cut-off wheels must be performed by a qualified operator following ANSI B7.1 safety guidelines. Inspect the wheel for cracks or chips before mounting and confirm the grinder RPM rating meets or exceeds the wheel's maximum rated speed. Always power down and disconnect the air supply before changing wheels. Use the correct arbor size and ensure the wheel guard is in place before operating.
