Metabo 616281420 Type 27 Grinding Wheel 4-1/2 in 24 Grit

Product Description

The METABO 616281420 is a Type 27 depressed center grinding wheel designed for aggressive material removal on angle grinders and right-angle grinders. The wheel measures 4.5 inches in diameter and 0.125 inches thick, with a 0.875-inch arbor hole for standard spindle mounting. The abrasive material is aluminum oxide at 24 grit, a coarse grit suited for heavy stock removal, weld grinding, and surface preparation on steel and ferrous metals. The resinoid bond holds the abrasive grain firmly under load. Maximum rated speed is 13,300 RPM. This wheel is sold individually and is a common consumable for metal fabricators, ironworkers, pipefitters, and general trade use.

This grinding wheel is used for rough grinding, weld seam removal, and deburring on flat and contoured ferrous metal surfaces. The Type 27 depressed center profile keeps the wheel hub above the work surface, allowing for a low grinding angle and improved clearance in tight spaces. It is appropriate for use on structural steel, pipe, plate, and weldments in both shop and field environments. The coarse 24-grit aluminum oxide construction removes material quickly, making it well suited to prep work prior to welding or coating.

Key Features

• Type 27 depressed center profile for low-angle grinding and improved clearance
• 24-grit aluminum oxide abrasive for aggressive, fast stock removal
• Resinoid bond construction resists loading and holds grain under sustained grinding pressure
• 13,300 RPM maximum rated speed compatible with standard 4.5-inch angle grinders
• Arbor hole connector type for secure spindle mount on common grinder tooling
• 0.23 pounds — lightweight for reduced operator fatigue during extended use

Compatibility

Designed as a direct-fit replacement or standard consumable for angle grinders and right-angle grinders accepting a 4.5-inch, 7/8-inch arbor Type 27 grinding wheel. Verify the grinder spindle speed rating meets or exceeds 13,300 RPM before use.

Installation Notes

Installation of grinding wheels must be performed by qualified personnel following ANSI B7.1 and applicable OSHA standards for abrasive wheel machinery. Always power down and disconnect the grinder from its power source before mounting or removing a wheel. Inspect the wheel for cracks or damage before installation and never exceed the maximum rated RPM marked on the wheel. Use the correct guard configuration for Type 27 wheels as required by the grinder manufacturer.
