3M 7000144145 Disc Pad Face Plate Ribbed 9 in Extra Hard

Product Description

The 3M 7000144145 is a ribbed disc pad face plate designed for use with 9-inch fibre discs in grinding and finishing applications. The ribbed construction reduces heat buildup during operation, allowing the disc to run cooler and extend consumable life. Rated extra hard and color-coded red, this face plate delivers firm, consistent backing pressure across the disc surface. It is compatible with both 4.5-inch disc pad hubs and 2.5-inch hubs, giving technicians flexibility in tool selection. Installation and removal are straightforward, making it a practical component for abrasive disc setups in metalworking and fabrication environments.

This face plate is suited for professional grinding and surface preparation tasks where fibre discs are the abrasive of choice. The 9-inch diameter matches standard 9-inch fibre disc sizes with a 7/8-inch arbor hole. It is commonly used in industrial fabrication, welding shops, and heavy-duty maintenance settings where controlling disc temperature and maintaining consistent backing hardness are priorities. Licensed tradespeople and experienced fabricators working with angle grinders or disc grinders will find this a direct-fit backing component for their existing pad hub assemblies.
