Forney Industries 71878 Type 27 Metal Grinding Wheel 20 Pack

Product Description

The Forney Industries 71878 is a Type 27 depressed-center grinding wheel designed for metal grinding applications. Measuring 5 inches in diameter, 0.25 inches thick, and with a 0.875-inch arbor hole, this wheel mounts on standard 5-inch angle grinders used throughout fabrication, welding, and general metalworking trades. The Type 27 profile—flat with a depressed center—allows the operator to work at a low grinding angle, which is the preferred geometry for surface grinding and weld blending on flat stock, pipe, and structural steel. This listing covers a package of 20 wheels, suitable for shop stocking or job-site supply.

This grinding wheel is used in professional metalworking environments including fabrication shops, structural steel erection, pipe fitting, and maintenance welding. It is well suited for removing weld beads, deburring cut edges, and general surface conditioning on ferrous metals. The 5-inch diameter is a common size compatible with widely used angle grinders found in both commercial and industrial settings. The 20-wheel pack quantity reduces reorder frequency for high-volume shops and contractors who burn through abrasives regularly.

Always power down and unplug or lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or damage before each use and confirm the grinder's rated RPM meets or exceeds the wheel's maximum RPM rating. Wear appropriate PPE including a face shield, gloves, and hearing protection during operation.
