3M 7000045659 Disc Pad Hub 4.5 in 5/8-11 Internal

Product Description

The 3M 7000045659 is a disc pad hub designed to mount abrasive disc pads onto right-angle grinders and similar rotary tools. The hub measures 4.5 inches in diameter and features a 5/8-11 internal thread, the standard arbor thread found on most angle grinders used in trade applications. It serves as the mechanical interface between the tool spindle and the backing pad, transferring rotational force to the abrasive. Metalworkers, fabricators, and finishing technicians install this hub when setting up grinding or surface-preparation assemblies. At 0.3 pounds, it adds minimal weight to the tool setup.

This disc pad hub is suited for use in metal fabrication shops, welding operations, and general industrial surface preparation. It is appropriate for both production environments and field service work where angle grinder disc pads require a reliable mounting point. The 5/8-11 internal thread makes it compatible with the majority of angle grinders sold in the North American market. Minimum order quantity from the supplier is 10 units per case, making it practical for shop stocking or fleet tool maintenance.

Key Features

• 5/8-11 internal thread matches the industry-standard spindle thread on most angle grinders
• Lightweight at 0.3 pounds, minimizing added load on the tool
• Sold in cases of 10 units, suitable for shop stock replenishment
• Functions as a direct mechanical interface between grinder spindle and abrasive backing pad

Compatibility

Designed for use with angle grinders equipped with a 5/8-11 spindle thread, which is the standard configuration for most right-angle grinders used in North American trade and industrial applications. Compatible with disc pads sized for 4.5-inch abrasive discs.

Installation Notes

Installation should be performed by a qualified technician familiar with angle grinder tool assembly. Disconnect the grinder from its power source or remove the battery before mounting or removing the disc pad hub. Thread the hub onto the spindle by hand first to avoid cross-threading, then secure according to the grinder manufacturer's torque guidance. Inspect the hub for cracks or thread damage before each use and replace if wear is present.
