Norton 662528-43584 Grinding Wheel Type 27 4.5 X 0.25 X 0.875 in

Product Description

The NORTON 662528-43584 is a Type 27 depressed center grinding wheel engineered for fast material removal on steel, ferrous metals, and aluminum. Manufactured under the Gemini line, it uses an A24S aluminum oxide abrasive specification, making it well-suited for aggressive grinding applications where consistent cut rate and wheel durability matter. The wheel measures 4.5 x 0.25 x 0.875 inches and carries a maximum operating speed of 13,580 RPM. It is sized and configured for use with standard 4.5-inch angle grinders, which are common tools in metal fabrication, pipefitting, welding shops, and structural steel work.

This grinding wheel is intended for use on carbon steel, stainless and other ferrous metals, and aluminum workpieces. The Type 27 depressed center profile allows the operator to work at a low angle to the surface, which improves control and reduces fatigue during extended grinding passes. Typical applications include weld seam grinding, surface conditioning, edge work, and stock removal in fabrication and maintenance settings. This wheel ships in a box quantity of 25 units.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety. Always confirm the grinder is unplugged or its power source is isolated before mounting or removing a wheel.
