Norton 66253364328 Surface Grinding Wheel 60 Grit 14 in

Product Description

The NORTON 66253364328 is a Type 5 surface grinding wheel engineered for demanding material removal on ferrous and non-ferrous workpieces. Built on a vitrified bond with a silicon carbide abrasive, this wheel delivers consistent stock removal at a medium grade (60 grit, I hardness code). The wheel measures 14 inches in diameter and 1-1/2 inches thick with a 5-inch arbor hole, a one-side recess of 1/2 inch depth and 8-inch recess diameter, and a rated maximum speed of 1,800 RPM. At 13.51 pounds, it is suited for stationary surface and cylindrical grinding operations where precision flatness and controlled cut rate are required.

This wheel is intended for use on surface grinders and cylindrical grinders in professional machine shop, fabrication, and industrial maintenance environments. Material applications include 300 series stainless steel, titanium, aluminum, brass, bronze, copper, gray iron, masonry, and natural stone. The silicon carbide grain structure makes it particularly effective on hard, brittle, or non-ferrous materials where aluminum oxide abrasives tend to load. This is a single-wheel package (Pkg Qty: 1).

Key Features

• Silicon carbide abrasive grain — effective on stainless steel, titanium, aluminum, copper alloys, masonry, and natural stone
• Vitrified bond provides rigidity and consistent cut geometry throughout wheel life
• Type 5 recessed profile (one-side recess, 1/2 inch deep, 8-inch recess diameter) for clearance on flanged arbors
• 60 grit medium grade (I hardness) balances material removal rate with surface finish quality
• Non-porous structure limits coolant absorption and maintains dimensional stability
• Rated to 1,800 RPM maximum — verify machine speed before mounting

Compatibility

Designed for use with surface grinders and cylindrical grinders. Compatible material applications include 300 Series Stainless, Titanium, Aluminum, Brass, Bronze, Copper, Gray Iron, Masonry, and Natural Stone as specified by the manufacturer.

Installation Notes

Installation should be performed by a qualified machine operator or tool room technician following the grinder manufacturer's wheel-mounting procedures and applicable ANSI B7.1 safety standards. Always power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the 1,800 RPM maximum rated speed marked on the wheel. Ensure flanges, blotters, and arbor hardware are clean and undamaged before securing the wheel.
