Norton 66252843598 Type 27 Grinding Wheel 5x1/4x7/8

Product Description

The NORTON 66252843598 is a Type 27 depressed center grinding wheel engineered for metal grinding applications. Built with Gemini aluminum oxide abrasive, it delivers consistent stock removal on ferrous metals and is designed for use with standard 5-inch angle grinders. The wheel measures 5 inches in diameter, 1/4 inch thick, and accepts a 7/8 inch arbor bore. The Gemini aluminum oxide grain is formulated to maintain cutting performance through the life of the wheel, reducing glazing and heat buildup during heavy grinding tasks. This wheel is a production-grade consumable suited for fabrication shops, maintenance crews, and field service technicians working on structural steel, pipe, and plate.

This wheel is intended for metal grinding on Type 27 angle grinders with a 5-inch guard and a 7/8 inch spindle. Typical applications include weld blending, surface prep, and material removal on mild steel, stainless steel, and other ferrous metals. The depressed center profile allows flat-to-workpiece contact for aggressive grinding at low approach angles. It is well suited to both shop and jobsite conditions where consistent abrasive performance across a full case quantity is required. The case quantity is 25 wheels per case.
