12E329 - Walter 6-Inch Green Silicon Carbide Bench Wheel 80 Grit with Bushings

Precision Grinding for Hardened Alloys and Carbide

The Walter 12E329 6" x 3/4" Bench Grinding Wheel is a high-performance abrasive solution engineered specifically for the unique demands of grinding extremely hard materials. Unlike standard aluminum oxide wheels which are designed for ferrous steels, this wheel is constructed from premium Green Silicon Carbide (GC). Silicon carbide is harder and sharper than aluminum oxide, allowing it to cut through tungsten carbide, titanium, and other non-ferrous metals with exceptional efficiency. The 80-grit composition offers a fine abrasive texture, making this wheel the ideal choice for sharpening operations where edge retention and surface finish are critical, such as re-facing carbide lathe tooling, sharpening masonry drill bits, or honing precision instruments.

Universal Compatibility and Balance

Industrial environments often utilize a variety of bench and pedestal grinders with differing shaft specifications. To address this, Walter Surface Technologies has equipped the 12E329 with a versatile nested reducer bushing system. While the wheel features a native 1-inch arbor, the included telescopic bushings allow for a secure, vibration-free fit on 3/4", 5/8", and 1/2" shafts. This universality simplifies inventory management for MRO departments, as a single SKU can service multiple machines across the facility. Furthermore, each wheel undergoes rigorous balancing during manufacturing to ensure concentricity, minimizing runout and reducing wear on grinder bearings.

Vitrified Bond Technology

The structural integrity of the 12E329 is maintained by a high-quality vitrified bond. This bonding agent holds the abrasive grains securely until they dull, at which point they fracture to reveal new, sharp cutting edges. This self-sharpening action is crucial for maintaining a cool cut, preventing thermal damage or "burning" of sensitive carbide workpieces. Whether used in a tool and die shop, an automotive remanufacturing facility, or a general maintenance workshop, this green silicon carbide wheel delivers the consistency and longevity professionals expect from Walter abrasives.
