Norton 66252830838 Type 6 Grinding Wheel 5 in 60 Grit

Product Description

The NORTON 66252830838 is a Type 6 straight-cup grinding wheel engineered for precision tool grinding and surface grinding applications. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent stock removal and shape retention across a range of ferrous metals and high-speed steels. It carries a 60-grit, K-hardness (medium grade) specification, making it well-suited for moderate material removal where surface finish and wheel life are both priorities. Rated to a maximum of 4,585 RPM, the wheel measures 5 inches in diameter with a 1-1/2 inch overall thickness and a 3/8 inch face width. Licensed tradespeople and tool-room machinists install and operate this wheel on bench or pedestal grinding equipment.

This wheel is used in tool rooms, maintenance shops, and production environments for grinding carbide tooling, drill bits, cutting tools, and similar workpieces. The vitrified bond provides a rigid, open structure that resists glazing and maintains cutting action throughout the wheel life. The 1-1/4 inch arbor hole fits standard bench and pedestal grinder spindles common in commercial and industrial settings. The gray wheel color and non-porous construction align with the 32A60-KVBE specification, confirming the abrasive blend and bond system.

Key Features

• Aluminum oxide abrasive for reliable performance on ferrous metals and high-speed steels
• Vitrified bond construction resists glazing and maintains consistent cut rate
• 60 grit, K hardness (medium grade) balances stock removal with controlled surface finish
• Non-porous wheel structure supports dimensional stability under load
• Rated to 4,585 RPM maximum for safe use on standard bench and pedestal grinders
• Specification code 32A60-KVBE for direct cross-reference with tool room records

Compatibility

Designed as an OEM-style replacement or standard supply for bench and pedestal grinders accepting a 1-1/4 inch arbor hole and accommodating a Type 6 straight-cup wheel up to 5 inches in diameter.

Installation Notes

Grinding wheel mounting and dressing must be performed by a qualified operator or licensed tradesperson in accordance with ANSI B11.9 and applicable workplace safety codes. Always power down and lock out the grinder before changing wheels. Inspect the wheel for cracks or chips before mounting, and never exceed the 4,585 RPM maximum speed rating. Use the correct flange size and blotter paper rings as required, and perform a ring test prior to installation.
