Built for Low- to Medium-Pressure Applications and Edgework
3Mâ„¢ Cubitronâ„¢ II Rolocâ„¢ Durable Edge Disc 947A 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 dual combination of backing and weight add strength to the disc. In fact, these attributes were chosen carefully, so the disc could 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. Among backing weights, an X-weight is heavy, durable and quite stiff. The disc’s heavy-weight backing minimizes the likelihood of tearing.
3M Science, Applied with 3M Precision-Shaped Grain Technology
So what makes Cubitronâ„¢ II discs desirable? They’re engineered to cut fast, run cool and last long. The 3Mâ„¢ Cubitronâ„¢ II Rolocâ„¢ Durable Edge Disc 947A features 3M Precision-Shaped Ceramic Grain. This revolutionary technology features triangular shaped ceramic minerals. As those minerals wear during use, they fracture at angles that continually form sharp points. This allows the minerals to keep slicing through the substrate with ease, while helping the grain wear more evenly. Altogether, operators get an ongoing, consistent cut. Moreover, because the triangles are evenly spaced when adhered to the backing, the gaps between them 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.
Rolocâ„¢ Attachment for Ease of Use
Another benefit of 3Mâ„¢ Cubitronâ„¢ II Rolocâ„¢ Durable Edge Disc 947A is that it features a Rolocâ„¢ attachment system. Rolocâ„¢ attachments were designed to make 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 Rolocâ„¢ backup pad (sold separately). With the help of a Rolocâ„¢ 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 you a faster, more consistent cut each and every time.
