Norton 66252940885 Type 1 Grinding Wheel 7in 32A60-KVBE 5 Pack

Product Description

The NORTON 66252940885 is a Type 1 straight grinding wheel engineered for moderate to heavy grinding of tool steels and vanadium alloys. It uses a 32A aluminum oxide grain — a vitrified monocrystalline abrasive — that cuts cool and fast while requiring minimal dressing between passes. The wheel measures 7 inches in diameter, 0.5 inches wide, with a 1.25-inch arbor bore. The bond specification is 32A60-KVBE. This product ships as a 5-pack, making it suited for shops and service operations that cycle through wheels regularly. Licensed grinding professionals and toolroom machinists are the primary installers and users.

This wheel is designed for cylindrical grinding, surface grinding, and toolroom grinding applications. The 32A vitrified monocrystalline grain performs well at moderate to heavy feed rates, making it appropriate for production environments where consistent stock removal on tool steels and vanadium alloy workpieces is required. The vitrified bond supports controlled breakdown and self-sharpening action across these abrasive-demanding materials.

Key Features

• 32A vitrified monocrystalline aluminum oxide grain for cool, fast cutting
• Suitable for moderate to heavy feed rates with minimal dressing
• Type 1 straight wheel profile for cylindrical, surface, and toolroom grinders
• 1.25-inch arbor bore fits standard toolroom and production grinding spindles
• Sold as a 5-pack for reduced downtime in high-cycle operations

Compatibility

Designed as an OEM-style replacement or stock grinding wheel for Type 1 straight-wheel grinding machines used in cylindrical, surface, and toolroom grinding setups accepting a 7-inch diameter wheel with a 1.25-inch bore.

Installation Notes

Grinding wheel mounting and dressing should be performed by a qualified machinist or grinding equipment operator following ANSI B7.1 safety requirements for the use, care, and protection of abrasive wheels. Always power down and lock out the grinder before mounting or removing a wheel. Inspect each wheel for cracks or chips before installation and perform a ring test per ANSI B7.1 guidelines. Never exceed the maximum operating speed marked on the wheel.
