Blue Tool Room Grinding Wheel – 30A Grade The Blue Tool Room Grinding Wheel (30A Grade) is a high-performance vitrified grinding wheel engineered for precision toolroom applications. Manufactured with a 30% ceramic and 70% aluminum oxide blend, this wheel delivers aggressive cutting action, excellent form holding, and extended wheel life. Designed for demanding grinding operations, the 30A grade allows for material removal of up to 0.004″ per pass, making it ideal for surface grinding, tool sharpening, and precision metalworking where control and consistency are critical. Key Features 30A Abrasive Blend – Combines ceramic grain for aggressive cutting with aluminum oxide for durability and smooth performance. High Stock Removal Capability – Designed to remove up to 0.004″ per pass while maintaining control and finish quality. Vitrified Bond Construction – Provides excellent wheel stability, form retention, and predictable wear. Extended Wheel Life – Balanced grain structure reduces glazing and improves grinding efficiency. Tool Room Performance – Ideal for precision grinding where accuracy and repeatability matter. Ideal For Tool room grinding Surface grinding Tool sharpening and reconditioning Precision metal removal Carbon steel, alloy steel, and tool steel applications Hardness Reference Wheel hardness affects cutting aggressiveness and wheel wear.
