3M™ Cubitron™ II Roloc™ Durable Edge Disc 947A has a name that precedes it. This disc reflects the benefits of Cubitron™ II and Roloc™ products — coupling the sharp, consistent cutting action of Cubitron™ II discs with an easy-to-use Roloc™ attachment. Built for durability and strength, it's great for edge work, because it stands up to edges without tattering or fraying.

  • 3M Precision-Shaped Grain delivers sharp, cool, consistent cutting action
  • Evenly-spaced grain features gaps that help debris escape, bolstering abrasive's ability to resist loading
  • Poly-cotton backing offers great tensile strength, helping enhance overall abrasive durability
  • Heavy X-weight backing does not wear and tear easily, rendering the disc a good match for edgework
  • Roloc™ attachment makes disc to tool attachment swift and easy

Built for Low- to Medium-Pressure Applications and Edgework

3M™ Cubitron™ II Roloc™ Durable Edge Disc 947A is a small-sized disc that was built for low- to medium-pressure applications that require edgework. Its small size makes it nimble and maneuverable, so operators can get in, over and around intricate parts. The disc's dual combination of backing and weight add strength to the disc, making it withstand wear from edges. The poly-cotton backing is a polyester and cotton blend, which makes it more durable than cotton alone and offers good tensile strength with more water resistance. The disc's heavy-weight backing minimizes the likelihood of tearing.

3M Science, Applied with 3M Precision-Shaped Grain Technology

The 3M™ Cubitron™ II Roloc™ Durable Edge Disc 947A features 3M Precision-Shaped Ceramic Grain, which is engineered to cut fast, run cool and last long. This revolutionary technology features triangular shaped ceramic minerals that continually form sharp points as they wear during use. This allows the minerals to keep slicing through the substrate with ease, while helping the grain wear more evenly. The evenly spaced triangles permit dust and debris to escape, minimizing loading. The disc is available in 40, 60, 80 and 120 grit, so operators can choose the grade most fitting for their application.

Roloc™ Attachment for Ease of Use

3M™ Cubitron™ II Roloc™ Durable Edge Disc 947A features a Roloc™ attachment system, which makes disc-to-tool connections quicker, faster and more efficient. This particular disc is available in a TSM (metal) or TR (plastic) attachment. With a simple 1/2 twist, operators can secure or detach a disc from a Roloc™ backup pad (sold separately). With the help of a Roloc™ attachment, operators may enhance overall productivity.

Altogether, 3M™ Cubitron™ II Roloc™ Durable Edge Disc 947A was designed with speed and durability in mind — engineered to give operators a faster, more consistent cut each and every time.
