3M 7100142460 Disc Sander 4 to 5 Inches 1 Hp Right Angle

Product Description

The 3M 7100142460 is a right-angle pneumatic disc sander rated at 1 HP and designed for use with 4-inch, 4.5-inch, and 5-inch coated abrasive and surface conditioning discs. The tool accepts discs with a minimum operating speed (MOS) rating of 12,000 RPM or greater, making it suitable for aggressive material removal and surface prep work. The spindle uses a 5/8-11 external thread. A right-angle steel gear head with a grease fitting is built into the tool for extended gear service life. Rear exhaust routing keeps debris and air discharge away from the work surface. A removable side handle ships with the tool, and a 3/8-inch to 1/4-inch air inlet reducer is included for flexible air-line hookup.

This disc sander is suited for metal fabrication, weld prep, surface conditioning, and finishing tasks in industrial, commercial, and heavy-trade environments. It is commonly used by pipefitters, ironworkers, sheet metal tradespeople, and maintenance mechanics working on structural steel, stainless, and similar substrates. The ergonomic housing incorporates 3M gripping material molded directly into the tool body, improving control during extended use on vertical or overhead surfaces.
