3M 7000121900 Non-woven Abrasive Disc 10 Inch Ao

Product Description

The 3M 7000121900 is a high-strength non-woven nylon abrasive disc designed for light deburring, surface cleaning, and final finishing on metallic workpieces. Built with Aluminum Oxide mineral, the disc cuts cleanly and produces a consistent scratch pattern across ferrous and non-ferrous metals. The dense, stiff open-web construction resists folding under pressure and stays load-resistant, limiting debris buildup that can prematurely clog the abrasive surface. At 10 inches in diameter with a 1/2 inch arbor, this disc is sized for bench grinders and right-angle disc machines used in fabrication and finishing operations.

This disc suits metal fabrication shops, maintenance technicians, and finishing professionals working on light deburring and pre-polish surface prep. The open-web structure conforms to irregular surfaces and edges without gouging the substrate, making it well suited for parts that require a smear-free, uniform final finish. The 10 inch diameter and center-hole design fit a range of medium to large disc tool setups. This product is sold individually and carries a minimum order quantity of 10 units per purchase.

Installation Notes

Installation is typically performed by metal fabricators or maintenance technicians familiar with abrasive disc equipment. Power down and fully de-energize the grinder or disc machine before mounting or removing any abrasive disc. Confirm that the arbor size and maximum RPM rating of the machine are compatible with this disc before operation. Follow all applicable ANSI B7 abrasive safety standards and wear appropriate PPE including eye protection and gloves during use.
