3M Roloc Disc 777F, 40 YF-weight, TR, 4 in, Die R400BB, 25/Carton, 100 ea/Case

• 3M Roloc attachment system enables efficient and secure attachment and removal of the disc
• A blend of ceramic and aluminum oxide mineral self-sharpens and offers improved durability and cut-rate over aluminum oxide
• Grinding aid reduces grinding temperatures for processes involving heat-sensitive alloys such as stainless steel, nickel alloys, and titanium
• Heat-resistant resin coating bonds abrasive to backing for durability under pressure, heat, and water
• Polyester backing is extremely tough to support medium-pressure applications while maintaining consistent performance in both wet and dry applications

3M Roloc Disc 777F features 3M-engineered high-performing ceramic abrasive grain blended with aluminum oxide for a combination of durability and cutting efficiency that increases productivity for both stock removal and finishing. The heavy, water-resistant polyester backing supports medium-pressure applications, a consistent cut-rate, and both wet and dry applications.

Our 3M Roloc Disc 777F is resin-bonded to withstand high heat and pressure. A grinding aid on the 777F disc reduces grinding temperatures to protect heat-sensitive alloys such as stainless steel and nickel alloys.

3M Ceramic Abrasive Grain is a ceramic mineral designed to enhance toughness and hardness of the grain. For increased performance, 3M Roloc Disc 777F products feature aluminum oxide mineral blended with 3M Ceramic Abrasive Grain which is one of the hardest, longest-lasting minerals available. Perfect for moderate to heavy stock removal, ceramic abrasives are engineered to cut fast and handle intense heat and stress applications. Ceramic aluminum oxide blends surpass aluminum oxide abrasives in cut-rate and durability making them an excellent choice for difficult grinding applications.

3M Roloc Disc 777F is available for use with the following Roloc attachment systems: TSM, TR, TP and TS. Please select discs with the attachment design made for your system.

Trusted 3M Roloc Model

The 3M Roloc Disc 777F combines the trusted 3M brand with a specific model designed for reliable performance. This disc features the 40 YF-weight grade, ensuring a balance of durability and cutting power for various grinding tasks.

Its unique Roloc attachment system allows quick and secure disc changes, making it ideal for users who need efficiency. The 777F model is engineered to handle demanding applications with consistent results.

Durable Backing Material

This disc uses a heavy polyester backing that supports medium-pressure applications. The backing is tough enough to maintain consistent performance whether used in wet or dry conditions, enhancing versatility on the job.

The 4 inch size of the disc fits many common grinders, providing a practical dimension for stock removal and finishing. The backing’s water resistance also helps extend the disc’s life in challenging environments.

Advanced Abrasive Blend

The 3M Roloc Disc 777F features a blend of ceramic and aluminum oxide minerals. This combination self-sharpens during use, improving durability and cut-rate compared to standard aluminum oxide abrasives.

This abrasive mix is perfect for moderate to heavy stock removal, offering fast cutting and the ability to handle intense heat and stress. It’s a smart choice for tough grinding jobs requiring long-lasting performance.

Heat-Resistant Coating Benefits

A heat-resistant resin coating bonds the abrasive to the backing, enhancing durability under pressure, heat, and water exposure. This coating helps the disc maintain its integrity during demanding grinding tasks.

Additionally, a grinding aid reduces temperatures during use, protecting heat-sensitive alloys like stainless steel, nickel alloys, and titanium. This feature extends the disc’s usability on delicate materials.

Convenient Pack Size Format

The 3M Roloc Disc 777F comes in a pack of 25 discs per carton and 100 discs per case. This packaging supports efficient inventory management for workshops and industrial users.

The discs are designed for the TR attachment system but are also compatible with TSM, TP, and TS systems. This flexibility ensures users can select the right disc for their specific tool setup.
