Value Collection BD3052 Type 27 Grinding Wheel 4.5 in 24 Grit

Product Description

The VALUE COLLECTION BD3052 is a Type 27 depressed center grinding wheel designed for aggressive material removal on metal surfaces. Measuring 4.5 inches in diameter and 0.25 inches thick, it uses an aluminum oxide abrasive bond rated at coarse 24 grit for fast stock removal on welds, castings, and structural steel. The resinoid bond holds the abrasive firmly under load, and the hard grade (hardness code U, spec designation A24U) provides consistent cut throughout the wheel life. It is rated to a maximum of 13,300 RPM and mounts via a standard 5/8-11 threaded arbor, making it compatible with most 4.5-inch angle grinders used in fabrication, construction, and maintenance trades.

This wheel suits metalworking applications where rapid grinding and weld blending are required. Typical users include ironworkers, pipefitters, fabricators, and maintenance technicians working on carbon steel, stainless, and cast iron. The Type 27 raised-hub profile keeps the disc at a low grinding angle, reducing operator fatigue during extended flat-surface work. It is sold individually but requires a minimum order quantity of 25 units, making it appropriate for shop stocking or job-site supply replenishment.

Key Features

• Type 27 depressed center profile for flat and surface grinding at low angles
• Aluminum oxide abrasive at 24 grit coarse grade for fast material removal
• Resinoid bond construction with hard wheel grade (hardness code U)
• 13,300 RPM maximum speed rating for use on standard 4.5-inch angle grinders
• 5/8-11 threaded connector for direct mount to common grinder spindles
• Spec designation A24U for straightforward cross-reference and reordering

Compatibility

Designed for use with 4.5-inch angle grinders equipped with a 5/8-11 threaded spindle. Verify that the grinder's no-load RPM does not exceed the 13,300 RPM maximum wheel rating before mounting.

Installation Notes

Mounting and use of grinding wheels should be performed by qualified personnel following ANSI B7.1 safety standards for abrasive wheels. Always inspect the wheel for cracks or damage before mounting and never exceed the marked maximum RPM. Ensure the grinder is unplugged or the power source is locked out before changing wheels. Use the appropriate wheel guard and personal protective equipment, including a face shield, during operation.
