Norton 66252941644 Type 12 Grinding Wheel 7 in 46 Grit

Product Description

The NORTON 66252941644 is a Type 12 vitrified aluminum oxide grinding wheel designed for precision tool grinding and surface conditioning applications. At 7 inches in diameter with a 7/16-inch face width and 1/2-inch overall thickness, this wheel fits standard bench and pedestal tool grinders. The 46-grit coarse cut and K-hardness (medium) bond rating make it well suited for aggressive stock removal on tool steel and similar ferrous materials. The vitrified bond provides consistent cut and open grain action. Maximum operating speed is 3,600 RPM. Licensed HVAC, plumbing, and mechanical trades techs who maintain cutting tools in-shop will recognize the 32A46-KVBE specification as a standard Norton abrasive designation.

This wheel is intended for use on bench grinders and pedestal grinders in commercial and light industrial shop environments. It is commonly used to dress, sharpen, and recondition hand tools, drill bits, cutting inserts, and other shop tooling. The 1-1/4-inch arbor hole fits most standard bench grinder spindles. The gray aluminum oxide construction and non-porous vitrified bond make it appropriate for dry grinding of carbon steel, alloy steel, and general-purpose tool maintenance tasks. It is sold individually with a minimum order quantity of one.

Installation Notes

Installation and dressing of grinding wheels should be performed by a qualified operator following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation and perform a ring test; never mount a damaged wheel. Do not exceed the 3,600 RPM maximum speed rating stamped on the wheel.
