Dynabrade 50192 Disc Backing Pad 3/8-24 Female Thread

Product Description

The DYNABRADE 50192 is a disc-style backing pad designed to mount abrasive discs on pneumatic and electric right-angle grinders and sanders. It uses a 3/8-24 female threaded mount for secure tool attachment and is rated to a maximum of 12,000 RPM. The threaded mounting interface provides a rigid, centered connection that minimizes disc runout during operation. This backing pad is intended for use with locking-type discs and is a direct replacement component for compatible DYNABRADE tools. Installation is performed by abrasive tool operators, grinding technicians, and surface prep professionals across metal fabrication, auto body, and industrial maintenance applications.

This backing pad is suited for surface grinding, blending, and finishing operations where a secure disc-to-tool connection is required. It is compatible with locking-type abrasive discs and is used in environments where controlled material removal and consistent surface contact are priorities. Typical applications include weld blending, deburring, and surface conditioning on metal and composite substrates in both shop and field settings.

Key Features

• 3/8-24 female threaded mount for direct attachment to compatible tool spindles
• Rated to 12,000 RPM maximum for use with high-speed pneumatic and electric grinders
• Designed for use with locking-type abrasive discs for positive disc retention
• Threaded mount type provides centered, rigid disc seating to reduce runout
• Replacement-grade component suitable for routine maintenance of abrasive tool setups

Compatibility

Designed for use with locking-type abrasive discs on DYNABRADE tools equipped with a 3/8-24 threaded spindle. Verify spindle thread specification and maximum RPM rating of the host tool before installation.

Installation Notes

Installation should be performed by a qualified abrasive tool operator or maintenance technician. Disconnect the tool from its air supply or power source before removing or installing the backing pad. Thread the pad onto the spindle by hand and ensure it is fully seated before mounting an abrasive disc. Never exceed the 12,000 RPM maximum speed rating, and always confirm that the abrasive disc speed rating meets or exceeds the tool's operating speed.
