Designed with a strong polyester film backing and sharp diamond mineral, the 3M™ Diamond Microfinishing Film Disc 675L delivers fine finishes on hard metals, thermal spray coatings, ceramics, carbides, chilled iron, and granite.The 3M Diamond Microfinishing Film PSA Disc 675L helps operators swiftly and effectively remove thermal spray coatings, ceramics, carbides, chilled iron, and granite. It is commonly used in the transportation, general industrial, precision grinding and finishing and aerospace industries. Diamond cuts well when moderate to medium pressure is applied. It offers an efficient alternative in most applications except those requiring the finest possible finishes. Altogether, diamond mineral renders this disc a great option for tough coating and hard-to-grind material removal. The polyester backing on the 3M Diamond Microfinishing Film PSA Disc 675L is water-resistant, so the disc may be run wet if desired. Adding a lubricant like water can help minimize build up and wash away swarf, which prevents the abrasive from getting clogged, and helps keep the abrasive cutting sharp and running cool. This disc includes a pressure-sensitive adhesive (PSA) to make disc tool attachment quick and easy. The PSA backing holds the disc securely in place during use, and removes cleanly from the backup pad (sold separately), leaving an uncontaminated surface for the next disc. This disc is designed for use with orbital and random orbital sanders.
