Value Collection BD3055 Type 27 Grinding Wheel 4.5 in 24 Grit

Product Description

The VALUE COLLECTION BD3055 is a Type 27 depressed center grinding wheel designed for aggressive material removal on metal, weld seams, and fabricated surfaces. The wheel measures 4.5 inches in diameter with a 0.25-inch thickness and accepts a 0.875-inch arbor for use with standard 4.5-inch angle grinders. It features a 24-grit aluminum oxide abrasive bonded with a resinoid bond, rated for a maximum of 13,300 RPM. The coarse grit and hard wheel grade make it well suited for rough grinding, burr removal, and surface prep work where speed of cut matters more than finish quality. Metalworkers, fabricators, and maintenance tradespeople are the primary installers and users of this wheel.

This wheel is appropriate for use in industrial fabrication shops, maintenance and repair operations, and construction environments. It fits 4.5-inch angle grinders with a standard 0.875-inch arbor and is best applied to ferrous metals, cast iron, and weld dressing tasks. The Type 27 depressed center profile provides clearance for flat and inside-radius grinding where a flat Type 1 wheel would contact the workpiece edge. It is sold individually, with a minimum order quantity of 5 units per purchase.

Installation Notes

Grinding wheels must be mounted and changed by qualified personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always inspect the wheel for cracks or chips before mounting and perform a ring test where applicable. Ensure the grinder is disconnected from power before changing wheels, and confirm that the grinder spindle speed does not exceed the 13,300 RPM rating stamped on the wheel. Use the correct flanges and never exceed the rated speed under any operating condition.
