Norton 66252837420 Vitrified Toolroom Wheel Type 1 60 Grit

Product Description

The NORTON 66252837420 is a Type 1 straight vitrified toolroom grinding wheel built for precision surface, cylindrical, and tool-and-cutter grinding operations. It uses a monocrystalline aluminum oxide grain at 60 grit, a medium-coarse cut suited to moderate to heavy stock removal. The vitrified bond provides rigid form holding and consistent geometry throughout the wheel's life. This wheel is sized for bench or pedestal grinder use in MRO shops, small job shops, and production environments where consistent cutting performance and dimensional accuracy are required. Installation and dressing are handled by qualified grinding machine operators or tool-and-cutter grind technicians.

This wheel is well matched to surface grinders, cylindrical grinders, and tool-and-cutter grinders in both small shop and production settings. It performs across a wide range of ferrous applications, with particular strength in grinding all categories of tool steels, including tough vanadium alloy steels. The 60-grit specification targets moderate to heavy material removal rather than finish grinding. Its cool, fast cutting action reduces heat buildup at the workpiece, which is a meaningful advantage when working high-alloy or heat-sensitive tool steels at moderate to heavy feed rates.

Key Features

• Monocrystalline aluminum oxide grain delivers sharp, strong cutting edges for medium to heavy stock removal
• Vitrified bond provides outstanding form holding and dimensional stability throughout wheel life
• Cool, fast cutting action minimizes heat generation at the workpiece surface
• Particularly effective on all tool steel types, including tough vanadium alloy steels
• Requires minimum dressing, reducing downtime between operations
• Type 1 straight profile is compatible with a wide range of surface, cylindrical, and tool-and-cutter grinder setups

Compatibility

Designed for use on surface grinders, cylindrical grinders, and tool-and-cutter grinders in ferrous and nonferrous MRO, small job shop, and production operations. Suitable for grinding all kinds of tool steels, including tough vanadium alloy steels.

Installation Notes

Grinding wheel mounting and dressing should be performed by a qualified operator following ANSI B7.1 safety standards. Always inspect the wheel for cracks or chips before mounting and perform a ring test prior to use. Power down and lock out the grinder before changing wheels. Never exceed the maximum RPM rating marked on the wheel.
