Forney Industries 71945 Strip Finish Disc 4.5in Type 27 20pk

Product Description

The Forney Industries 71945 is a heavy-duty strip and finish disc designed for aggressive surface preparation and finishing work on metal, wood, and painted surfaces. Measuring 4.5 inches in diameter with a 5/8 inch-11 arbor thread, this Type 27 disc mounts directly to standard angle grinders. It is engineered for tasks where conventional abrasive discs wear too quickly, offering durable material removal without loading. Metalworkers, fabricators, and general contractors rely on this disc for stripping rust, paint, mill scale, and coatings in demanding shop and field environments.

This disc is suited for use on angle grinders in both fabrication shops and on-site metalwork. The Type 27 depressed-center profile provides clearance for flat and flush grinding applications. Common uses include weld prep, rust removal, coating removal, and surface conditioning prior to painting or welding. Each package contains 20 discs, making it a practical choice for production environments or contractors who cycle through abrasives at a high rate.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with angle grinder safety practices. Always power down and disconnect the grinder before mounting or removing a disc. Confirm the grinder spindle speed rating meets or exceeds the disc maximum RPM before use. Inspect the disc for damage prior to each use and never operate a cracked or delaminated abrasive disc.
