Norton 66243529046 Type 12 Grinding Wheel 3 in 60 Grit

Product Description

The NORTON 66243529046 is a Type 12 vitrified grinding wheel designed for tool grinding and precision grinding operations. Built with aluminum oxide abrasive at 60 grit and K hardness (medium grade), it delivers consistent stock removal on ferrous metals and tool steel. The wheel measures 3 inches in diameter with a 1/2-inch thickness and a 1/2-inch hole size. It carries a maximum operating speed of 8,280 RPM. The vitrified bond provides rigidity and free-cutting action, making this wheel a standard choice for bench grinder and surface grinder applications in maintenance and toolroom environments.

This wheel is suited for sharpening and reconditioning cutting tools, drill bits, lathe tooling, and similar workpieces. The medium grit and hardness rating balance material removal rate with surface finish, making it appropriate for both rough shaping and light finishing passes on hardened tool steel. Machinists, toolroom technicians, and maintenance trades typically use this wheel on pedestal or surface grinding equipment.
