Norton 66252839428 Type 27 Grinding Wheel 6in Ceramic Alumina 24G

Product Description

The NORTON 66252839428 is a Type 27 depressed center grinding wheel designed for aggressive stock removal on metal surfaces. The wheel measures 6 inches in diameter and 1/8 inches thick, with a 7/8 inch arbor hole for direct mounting on standard angle grinders. The abrasive material is ceramic alumina at a coarse 24 grit, bonded with a resinoid bond for durability under heavy grinding loads. Rated to a maximum of 10,185 RPM, this wheel suits demanding fabrication, weld grinding, and surface preparation tasks performed by metalworkers, pipefitters, ironworkers, and maintenance technicians.

This wheel is built for use on angle grinders in industrial, commercial, and job-site environments. The Type 27 depressed center profile keeps the grinding face at the correct angle for flat and contoured workpiece surfaces. Typical applications include weld bead removal, deburring, surface conditioning on structural steel, pipe, and plate. The coarse 24 grit ceramic alumina construction cuts fast on ferrous metals and holds up to heat generated in continuous grinding operations.

Installation Notes

Installation should be performed by a qualified operator following the grinder manufacturer's mounting instructions and ANSI B7.1 safety requirements for abrasive wheels. Always power down and unplug the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before each use and never operate above the rated maximum RPM. Ensure the guard is properly positioned before starting the grinder.
