64860 115 MM™ HIGH PERFORMANCE RIBBED BACKING PAD 3M

3M™ High Performance Ribbed Backing Pad – Ø 115 mm, M14

The 3M™ High Performance Backing Pad (PN 64860) is a high-quality, rigid backing pad, specifically developed to optimize the performance of fiber discs in harsh industrial environments. Its advanced design combines operational flexibility with extreme durability.

Product Description

This backing pad features a unique ribbed surface pattern that directs all the pressure directly onto the abrasive grains. This design not only increases cutting aggressiveness, but also promotes air circulation, keeping the abrasive system at an optimal operating temperature even under intense stress.

Compatibility

This backing pad is not an isolated component, but serves as a critical support for the following systems:

• 3M™ Fibre Discs: Designed as the reference mount for the entire range of 115mm 3M fibre discs.
• 3M™ Cubitron™ II Systems: Specifically optimized for use with Cubitron™ II fiber discs (models 982C and 987C). Combined use increases disc life and cutting speed, resulting in increased productivity and dramatically reduced cost per workpiece.
• Power Tools: For use on 3M™ right angle grinders or compatible tools with a standard M14 threaded connection.

Advantages and Applications

The integration of this ribbed backing pad offers immediate benefits in the workshop:

• Performance Increase: Improves the removal capacity of fiber discs by more than 30%.
• Heat Resistance: Designed to withstand temperatures above 100°C (212°F) , preventing pad deformation and abrasive glazing.
• Cooler Cutting: The design promotes heat dissipation, protecting the integrity of the metal substrate.
• Versatility: Ideal for weld grinding, deburring, edge chamfering and surface preparation.
