Value Collection KP86227 Type 27 Grinding Wheel 4.5in

Product Description

The VALUE COLLECTION KP86227 is a Type 27 depressed center grinding wheel built for aggressive material removal on angle grinders and bench setups used in metal fabrication, weld prep, and surface conditioning. The wheel measures 4.5 inches in diameter and 0.25 inches thick, with a 0.875-inch arbor hole for standard 4.5-inch angle grinder spindles. The abrasive material is aluminum oxide, graded at A60R, making it well suited for ferrous metals including mild steel and cast iron. Maximum rated speed is 13300 RPM. This wheel is installed by fabricators, pipefitters, ironworkers, and maintenance mechanics who need a reliable, cost-effective consumable for daily grinding tasks.

This grinding wheel fits standard 4.5-inch angle grinders with a 7/8-inch arbor and is appropriate for both shop and field use. Typical applications include weld seam grinding, edge deburring, surface rust removal, and general stock removal on steel and iron workpieces. The Type 27 depressed center profile keeps the wheel body recessed below the guard plane, allowing flat or near-flat grinding contact with the workpiece surface. It is commonly used in structural steel shops, pipe fabrication yards, and general maintenance environments.

Installation Notes

Grinding wheel installation and replacement should be performed by qualified personnel familiar with abrasive wheel safety. Disconnect and lock out the grinder from its power source before changing the wheel. Verify the grinder spindle speed does not exceed the 13300 RPM maximum rating marked on the wheel before operation. Always inspect the wheel for cracks or damage before mounting, and ensure the proper guard is in place before resuming use, in accordance with ANSI B11 and OSHA 1910.243 abrasive wheel standards.
