Weiler 07701 Drive Arbor 7/8 in Arbor Hole 3/4 in Shank

Product Description

The WEILER 07701 is a drive arbor designed to mount 6-inch disc brushes onto angle grinders and similar rotary power tools. It converts a 7/8-inch arbor hole to a 3/4-inch shank diameter, providing a secure mechanical connection between the tool spindle and the brush. The arbor features an attached spindle and a flow-through spindle design, which allows coolant or air to pass through during operation. This component is typically installed by maintenance technicians, fabricators, and surface-preparation professionals working with abrasive and brush tooling in industrial or trade settings.

This drive arbor is intended for use with WEILER disc brushes, including Nylox disc brushes, mounted on 6-inch applications. The flow-through spindle design supports operations where debris clearing or coolant delivery through the spindle is required. The 3-inch bolt hole diameter and attached spindle configuration make it compatible with standard disc brush mounting arrangements used in metal finishing, weld cleanup, and surface conditioning work.
