Product Description

3M SandBlaster 9681 4-1/2-Inch Coarse Clean-N-Strip Disc

From the Manufacturer

Angle grinders have long been used by woodworkers and metalworkers for grinding, cutting and polishing. These tools, which operate at extremely high speeds (10,000 RPM and higher), are some of the most aggressive power tools on the market. In the past, they were rarely used for sanding, because the abrasives performed poorly and changing them required wrenches, which interrupted workflow. In an effort to expand the usage of these powerful tools, 3M has invented an entire new line of abrasives and a unique new method for changing discs. With these innovations, angle grinders can be used for the first time as versatile, highly effective sanding systems. 3M’s exclusive quick loading adapter is the hub of this new system. The adapter allows users to switch quickly and easily between a variety of abrasive discs-without using a wrench. Now a 4-Inch or 4-1/2-Inch angle grinder can become a versatile sanding tool capable of handling a wide range of sanding tasks. 3M SandBlaster 4.5-Inch clean-n-strip disc can be used on many surfaces and are great for removing and cleaning rust, paint and many other coatings.

Product Description

The 3M Hookit Film Disc 360L features an aluminum oxide abrasive grain on a film backing for effective fine sanding on plastics, gel coats and polyurethane solid surface substrates. The sturdy film backing gives the durability needed for a high-production environment, and its excellent resistance to edge tearing provides longer life over discs with standard A-weight paper backings.

From the Manufacturer

The film backing provides a close-tolerance, consistent finish, making it a good choice for applications such as spot repairs, sanding plastic parts, paint feathering on defects, or sanding automotive primer.

To help reduce loading on the disc, the 3M Hookit Film Disc 360L is designed with an open coat construction without a load-resistant stearate coating. The convenient 3M Hookit hook-and-loop attachment on the backing enables easy re-use so the disc can be used again and again for the life of the product, and attaches to the low-profile 3M Hookit Disc Pad (sold separately) on a random orbital sander. The Film Disc 360L comes in a range of grades for various applications from fine sanding to finishing.

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.

At 3M we offer a complete line of hook-and-loop style 3M Hookit discs for work spaces where adhesive backed discs may become contaminated by dust, dirt, or flying debris. They are often used in applications where a 3M Stikit disc may be too aggressive, as Hookit discs tend to leave finer finishes than adhesive backed discs. Hookit sanding discs conveniently and firmly attach to a hook-and-loop backup disc pad (sold separately) on a random orbital sander, can be removed cleanly and easily, and can be re-used again and again for the extent of the abrasive life.

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.
