To increase operator precision and help eliminate rework, we designed this tool with a variable speed control with variable speed trigger. This lightweight tool includes a comfortable full coverage composite grip that absorbs vibration and moderates cold temperatures caused by air flow. In addition, the 0.45 hp motor is precision balanced to ensure smoother and quieter operation than that of competitive sanders.

Our versatile tool provides dual mount capability that allows the user to switch between the direct mount, which provides greater visibility and maximum control, and the collet mount, which extends the reach of the tool when required for sanding hard-to-reach areas. The collet mount also provides compatibility with a wide range of abrasive products.

Included with the tool is a 1/4" 3M™ Roloc™ shank for use with the collet assembly (PN 45102). Also included is a 3" 3M™ Roloc™ TR hard disc pad (PN 45091), which attaches to the 1/4-20 external threaded shaft and provides convenient and secure attachment for any Roloc disc or bristle product with a TR button. The necessary air power supply and hose are not included.

The pneumatic 3M™ Pistol Grip Disc Sander 28547 is intended for intermittent spot repairs by skilled, trained professionals in accordance with the instructions in the user manual (included on the product page). Our 3M tool is optimized when paired with other 3M products, and is designed to be used with 3" and smaller Roloc disc pads as well as other coated and surface conditioning products used for sanding metals, wood, stone, plastics and other materials. Use in any other manner or with other accessories could lead to unsafe operating conditions. Tool RPM is 15,000—use only with disc pads and abrasives that have a Max RPM of at least 15,000.

We designed this tool to run on power generated by an air compressor (air hose and air compressor sold separately). Use a clean lubricated air supply that will give a measured air pressure of 22 standard cubic feet per minute (SCFM) and 6.2 bar or 90 pounds per square inch (psi) at the tool, i.e. the point where the air hose is connected to the tool, when the tool is running with the level fully depressed. The tool can be run at lower pressures but should never be run higher than 6.2 bar (90 psi). If run at lower pressure the performance of the tool is reduced. The recommended airline is an approved 3/8 inch (10 mm) airline at the minimum length required for the application, with a maximum length of 25 feet (8 m). For more details about connecting the tool to your air supply, see the User Manual.

Our 3M™ Roloc™ TR system was designed to provide a quick, secure attachment for products ranging in diameter from 1 to 4 inches. Roloc disc pads come in various densities or hardness levels depending on the requirements of the application. The hardness ranges from extra hard to soft, where the rule of thumb is the coarser the abrasive, the harder the disc pad one should use, which promotes longer life of the product. The disc pad (also called a backup pad) interlocks with the sanding disc or bristle disc and is attached to the disc sander. This simple assembly provides a secure attachment that is reliable even when working at high speeds. Combining a Roloc abrasive disc with a Roloc disc pad provides high-quality, consistent results.
