08B005 - Walter 08-B-005 Spindle Extension Adapter 7/16-20 to 3/8-24

Precision Spindle Adaptation for Industrial Grinding

The Walter Extension 7/16-20 X 3/8-24 (SKU: 08B005) is a specialized industrial accessory designed to bridge the gap between air grinder spindles and abrasive mounting systems. In the diverse world of metalworking tools, thread incompatibility can often hinder the deployment of the optimal abrasive product for a specific application. This precision-engineered adapter solves that challenge by converting between 7/16-20 and 3/8-24 thread standards, allowing for a seamless integration of backing pads, flap wheels, and other threaded abrasives onto your existing pneumatic tooling.

Manufactured by Walter Surface Technologies, a leader in surface treatment solutions, this extension is built to withstand the high rotational speeds and torque associated with industrial air grinders. Unlike generic adapters that may introduce runout or vibration, the 08B005 is machined to tight tolerances. This ensures that the center of gravity remains true, protecting both the tool's bearings and the operator from excessive vibration. The high-grade steel construction resists stripping and wear, providing a long service life even in demanding fabrication environments where tool changes are frequent.

This component is essential for MRO (Maintenance, Repair, and Operations) cribs and fabrication shops that utilize a variety of grinder brands and abrasive types. By standardizing connections or adapting specialty tools, this extension maximizes the utility of your tool fleet. Whether you are mounting a specific Walter backing pad or adapting a specialty finishing drum, this extension ensures a secure, safe, and efficient mechanical connection.
