Product Description

3M Roloc Disc 361F offers a quick-change attachment and provides durability and high performance for grinding, blending, deburring, and finishing on all metals Fast-cutting aluminum oxide abrasive grains are bonded to the heavyweight cloth backing with durable, heat-resistant resin that supports both wet and dry applications

From the Manufacturer

The 3M™ Roloc™ Disc 361F TR offers a quick-change attachment and provides durability and consistent performance for grinding, blending, deburring, and finishing on all metals. Fast-cutting aluminum oxide abrasive grains are bonded to the heavy YF-weight cloth backing with durable, heat-resistant resin that supports both wet and dry applications. The quick and easy Roloc TR attachment system works with Roloc TR disc pads to make changing discs as easy as a short twist to remove the disc, and a short twist to attach the next disc.

3M™ Roloc™ TR quick change discs are smaller discs that have a plastic threaded button designed to easily and quickly attach to a Roloc TR disc pad (sold separately) so that operators can conveniently change discs with a simple twist-off, twist-on motion. The Roloc TR system provides a secure attachment even for heavy-duty applications, and the variety of available 3M Roloc discs allows swapping from one application to the next in seconds. Each TR attachment button is also color-coded to identify its grade, making it easy to select the grade required for different applications.

Aluminum oxide mineral is a popular choice among industrial professionals because of its fast cut-rate and long life. This mineral makes a tough, durable abrasive that self-fractures to expose fresh cutting edges in use, whereas traditional abrasives such as garnet quickly wear down with use. Due to their fast cut-rate, hardness, strength, and low heat retention, they are widely used in grinding applications in addition to sanding and finishing applications. Aluminum oxide is suitable for a wide variety of materials in both woodworking and metalworking, including ferrous alloys.

Heat-resistant resin is a sturdy binding agent that adheres the abrasive to the backing and maintains the stability of the bond even in conditions of high heat or pressure.

Cloth-backed discs are known for their durability and flexibility. They’re a good first choice when working with metal or for heavy wood stock removal.

Product Description

3M Hookit Clean Sanding Disc 236U features a 3M proprietary multi-hole pattern that evacuates dust better than 5- or 6-hole products — dramatically increasing disc life. The design achieves an ideal balance between the abrasive surface and dust extraction holes to maximize cut and optimize the life of the disc.

From the Manufacturer

The 3M™ Clean Sanding Disc 236U offers superior dust control, aggressive cut, and long life on a premium aluminum oxide disc with a durable edge and convenient Hookit attachment. It features a 3M proprietary multi-hole Clean Sanding pattern that evacuates dust better than 5- or 6-hole products — dramatically increasing disc life. A go-to product in many industrial operations, this durable disc is well suited for high production sanding operations as well as general purpose applications. Choose this disc for blending and finishing on aluminum and carbon steel, and for woodworking applications such as heavy and medium stock removal and finishing on hardwoods, softwoods, and composites. This disc also works well on primer, paint, sealers, topcoats, fiberglass, and plastics. Designed for use with a random orbital sander, the strong C-weight paper backing resists tearing and edgewear during aggressive sanding, and the disc is resin-bonded for heat-resistance, further increasing life and cut. These discs also feature an open coat and a load-resistant coating to enhance dust management and cut-rate.

To achieve maximum dust extraction, use this disc with a 3M™ Clean Sanding Disc Pad and a 3M™ Random Orbital Sander with vacuum (both sold separately).

Sandpaper discs cut better and last longer when dust isn’t loading the cutting surface of the abrasives. Reducing dust is easier than ever with 3M Clean Sanding discs. The 3M proprietary multi-hole pattern on Clean Sanding products evacuates dust at a higher rate that 5- or 6-hole products. The multi-hole pattern achieves an ideal balance between the abrasive surface and dust extraction holes to maximize cut and optimize the life of the disc. This hole design doesn’t even require alignment of holes with the disc pad, making disc changes quick and simple. Suction via a vacuum system is drawn through the holes to collect dust from the air and workpiece, for improved working conditions, disc performance, and overall productivity.

Clean Sanding 236U discs also feature a load-resistant coating that allows the disc to continue cutting even when sanding softwoods, paints, and other materials that would, otherwise, clog the surface of the disc and hinder sanding ability. Loading is further reduced by an open coat, which means the abrasive grains are spaced slightly apart so that dust can escape rather than obstructing the cutting edge of the grains, thereby optimizing cut-rate and disc life.

Sanding discs come in a variety of forms to fit various power tools and disc pads. 3M Clean Sanding discs come with a 3M™ Hookit™ attachment. A Hookit disc conveniently and firmly attaches to a hook-and-loop backup disc pad (sold separately) on a random orbital sander. Hookit discs are quick and easy to change when switching from one grade to another, and can be reused again and again for the extent of the disc life (whereas adhesive-backed discs are typically discarded after one use because the adhesive backing will not re-adhere a second time).

Aluminum oxide is a popular choice among industrial professionals because of its fast cut-rate and long life. This mineral makes a tough, durable abrasive that self-fractures to expose fresh cutting edges, whereas traditional natural abrasives dull more quickly. Due to its fast cut-rate, hardness, and strength, it is widely used in grinding applications in addition to sanding and finishing applications. Aluminum oxide is suitable for a wide variety of materials in both woodworking and metalworking, including ferrous alloys.

From the Manufacturer

The 3M&#8482 NX Hook and Loop Paper Dust-Free Disc is ideal for use with portable sanders on a variety of substrates where dust-control is a concern. It offers aggressive cut and long life along with dust-free sanding. Constructed of aluminum oxide abrasive on intermediate-weight paper (D-weight for grades 40, P60, P80; C-weight for grades P100–P800), it is well suited for high production operations as well as general purpose applications on whitewood, metal, composites, primer, paint, sealers, and topcoats. The 6-hole dust management feature works with a vacuum system (not included) to control dust in the air and on the workpiece, while an open coat construction and a load resistant coating help prevent clogging when working with softwoods or paint. The disc features a hook-and-loop backing that provides ease of attachment and reuse, and the durable paper backing stands up to extended use with dual action or random orbital sanders.

The 6-hole pattern dust management system uses a series of evenly-spaced holes in the abrasive disc that are aligned with the holes in the backup pad, and is used on 6″ discs. When used with a vacuum system and 3M&#8482 6-hole dust-free backup pad (both sold separately), suction is drawn through the holes to help collect the dust from the air and on the workpiece, for improved working conditions and increasing productivity. A load-resistant coating further prevents wood dust, paint particles, and other debris from prematurely clogging the surface of the disc, optimizing cut-rate and disc life.

Hook and Loop sanding discs are designed to be used with a random orbital sander, a handheld sanding machine that rotates the disc in a random pattern to prevent swirl marks from forming on the surface of the workpiece. The sander is fitted with a disc pad (or backup pad), to which the sanding disc is attached. Hook-and-loop discs are quick and easy to change when switching from one grade to another, and can be reused again and again until worn out (whereas adhesive-backed discs are typically discarded after one use because the adhesive backing will not re-adhere a second time).

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.
