12E008 - Walter 1-Inch to 7/8-Inch Arbor Adapter Bushing (2-Pack)

Precision Arbor Adaptation for Industrial Abrasives

The Walter 12E008 Bushing is a critical accessory for metalworking professionals and industrial facilities that manage a diverse inventory of abrasive wheels and grinding equipment. Designed to seamlessly reduce an arbor hole size from 1 inch to 7/8 inch, this bushing ensures that wheels manufactured with larger centers can be safely and effectively mounted onto tools with standard 7/8-inch spindles. In high-throughput environments, having the flexibility to adapt consumables to available machinery is vital for maintaining uptime and efficiency.

Manufactured by Walter Surface Technologies, a leader in surface treatment solutions, these bushings are engineered for precision. A loose or ill-fitting wheel can cause dangerous vibrations, poor finish quality, and premature wear on power tool bearings. The 12E008 bushing eliminates these risks by filling the gap between the spindle and the wheel bore with a tight, concentric fit. This ensures that the abrasive media spins true, maintaining balance even at high rotational speeds. The result is a safer operation for the user and a longer lifespan for both the abrasive and the grinder.

This product is supplied as a pack of two, providing excellent value and ensuring that a spare is always on hand. Whether you are adapting bench grinding wheels, large cut-off wheels, or specialized flap discs, these bushings provide the necessary interface for secure mounting. They are simple to install—requiring no special tools—and are designed to stay in place during operation. For shops that stock multiple sizes of abrasives or utilize various brands of equipment, the Walter 12E008 is an indispensable component of the tool crib.

Safety is paramount in grinding operations. Using a wheel without the correct arbor size is a significant hazard. These bushings provide a certified solution from a trusted manufacturer, giving safety officers and operators peace of mind. By standardizing the fit of your abrasives, you reduce the likelihood of operator error and ensure that every wheel is mounted according to best practices.
