Norton 66252830987 Type 6 Grinding Wheel 5 in 60 Grit

Product Description

The NORTON 66252830987 is a Type 6 straight-cup grinding wheel designed for tool grinding and surface grinding applications. Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent stock removal on ferrous metals and tool steels. The wheel measures 5 inches in diameter with a 2-inch overall thickness and a 0.5-inch face width. It carries a 60-grit medium grade (Hardness Code J) and is rated to a maximum of 4,585 RPM. Specification code 32A60-JVBE identifies the exact abrasive formulation for replacement or cross-reference. Licensed machinists, tool-and-die shops, and HVAC or industrial maintenance techs performing tool reconditioning are the primary installers.

This wheel fits bench grinders and pedestal grinders configured for Type 6 straight-cup geometry. It is suited for offhand grinding, tool sharpening, and light surface work on carbon steel, high-speed steel, and similar ferrous materials. The 5/8-inch hole size is standard for many bench grinder spindles. Because this is a non-porous vitrified wheel, it performs well in both dry and light wet grinding conditions without absorbing coolant or losing bond integrity under normal shop use.

Key Features

• Aluminum oxide abrasive for reliable stock removal on ferrous metals and tool steels
• Vitrified bond provides consistent grain exposure and long wheel life
• 60-grit medium grade for balanced cut rate and surface finish
• Hardness Code J for moderate wheel hardness suitable for a wide range of tool grinding tasks
• Non-porous construction resists coolant absorption and maintains structural integrity
• Specification code 32A60-JVBE for precise identification and reorder

Compatibility

Designed as an OEM-style replacement grinding wheel for bench grinders and pedestal grinders accepting Type 6 straight-cup wheels with a 5/8-inch arbor hole.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician familiar with abrasive wheel safety. Power down and lock out the grinder before mounting or removing any wheel. Inspect the wheel for cracks or chips before installation and perform a ring test per ANSI B7.1 guidelines. Never exceed the rated maximum of 4,585 RPM; confirm the grinder spindle speed before use.
