Norton 662530-44092 Straight Toolroom Grinding Wheel Type 01

Product Description

The NORTON 662530-44092 is a Type 01 straight toolroom grinding wheel designed for fast, cool stock removal on hard metals and precision tooling. Built with a self-sharpening ceramic alumina and friable aluminum oxide abrasive blend (SG 5SG CA), this wheel delivers roughly twice the rough stock removal rate of conventional abrasives while minimizing heat buildup and reducing the frequency of dressing. The high-performance bond maintains form integrity across extended production runs. At 8 inches in diameter, 0.5 inches wide, and with a 1.25-inch arbor bore, it is sized for standard cylindrical and surface grinder spindles. Licensed machinists and tool grinders install and operate this wheel in shop and production environments.

This wheel is suited for use on CNC cutting tool machines, cylindrical grinders, and surface grinders. It is engineered for grinding titanium, aerospace and other super alloys, cast iron, ductile iron, gray iron, hard-carbon steel, tool steel, and 400-series stainless steel. It is also appropriate for sharpening and reconditioning cutting tools and dies where edge retention and minimal burn are critical. This wheel is sold individually and is appropriate for both production shop and toolroom applications where consistent, repeatable results are required.

Key Features

• Self-sharpening ceramic alumina and friable aluminum oxide blend (SG 5SG CA) for fast, cool cutting
• Delivers approximately 2x rough stock removal compared to conventional abrasive wheels
• Wheel life rated at 3 to 5 times longer than standard aluminum oxide wheels
• High-performance bond provides strong form holding and versatility across a range of workpiece materials
• Minimizes burn and dressing frequency, extending tool and die edge life in production
• Type 01 straight profile fits standard cylindrical and surface grinder configurations

Compatibility

Designed for use with CNC cutting tool machines, cylindrical grinders, and surface grinders equipped with a 1.25-inch arbor. Compatible workpiece materials include titanium, aerospace and super alloys, cast and ductile iron, gray iron, hard-carbon steel, tool steel, and 400-series stainless steels.

Installation Notes

Grinding wheel installation must be performed by a qualified operator following ANSI B11.9 and OSHA 29 CFR 1910.215 standards for abrasive wheel machinery. Always power down and lock out the grinder before mounting or dismounting the wheel. Inspect the wheel for cracks or chips before installation using the ring test, and never exceed the rated maximum operating speed marked on the wheel. Dress the wheel before first use to ensure proper face geometry and running concentricity.
