Norton 66252830846 Type 6 Grinding Wheel 60 Grit

Product Description

The NORTON 66252830846 is a Type 6 straight-cup grinding wheel designed for precision tool grinding and surface grinding applications. Built with white aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent stock removal and sharp cutting action on ferrous metals and tool steels. It measures 5 inches in diameter with a 1-1/2 inch overall thickness and a 3/8 inch face width, fitting spindles through a 1-1/4 inch hole. Rated at a maximum of 4,585 RPM, it carries a K hardness code (medium grade) and a 60 grit classification, making it well-suited for moderate stock removal with reasonable surface finish.

This wheel is used primarily in bench grinder and pedestal grinder setups found in machine shops, tool rooms, and maintenance facilities. The aluminum oxide composition and vitrified bond perform reliably on high-speed steel, carbon steel, and similar ferrous materials. The medium grade and 60 grit are a common combination for sharpening lathe tools, drill bits, and general-purpose tool reconditioning. It is typically installed and used by machinists, tool-and-die professionals, and industrial maintenance technicians.

Key Features

• Type 6 straight-cup profile with 3/8 inch face width for controlled contact grinding
• White aluminum oxide abrasive — friable grain for cool cutting and self-dressing action
• Vitrified bond provides rigidity and consistent performance across the wheel life
• 60 grit medium grade balances material removal rate with surface finish quality
• K hardness code suits a wide range of ferrous tool grinding tasks
• Rated to 4,585 RPM maximum — matched to standard bench and pedestal grinder spindle speeds

Compatibility

Designed as an OEM-style replacement or standard-fit grinding wheel for Type 6 straight-cup wheel positions on bench grinders and pedestal grinders accepting a 1-1/4 inch arbor hole and a 5 inch diameter wheel.

Installation Notes

Grinding wheels must be installed by a qualified technician following ANSI B11.9 and applicable shop safety standards. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the rated maximum RPM marked on the wheel. Use the correct flanges and blotters as specified by the grinder manufacturer.
