3M™ Forked Spindle, 45121, silver, 3 in x 1/16 in x 3/4 in x 1/4 in (76.2 mm x 1.60 mm x 19.05 mm x 6.35 mm)

The 3M™ Forked Spindle was designed to bring those seemingly hard-to-reach workpiece areas within reach. It can be tough to access internal diameters with other types of abrasives – be they wheels, brushes, or discs, and that’s why this accessory was created. When you find yourself in a tight corner or hole, turn to the 3M™ Forked Spindle.

Often times, operators aspire to achieve smooth finishes, polishes, and seamless welds on their workpieces. Yet, intricate parts can present a challenge: how do you navigate small corners and tight spaces? The 3M™ Forked Spindle is made to help operators access these hard-to-reach areas. That way, no workpiece area need go unfinished. Using the 3M™ Forked Spindle is simple. Much like a mandrel, it fastens to a die grinder or other rotary tool (sold separately). Its design differs from a mandrel, however, because it has a fork-shaped end. Instead of extending the reach of a disc – like a mandrel – the forked spindle itself gets in, over, and around the workpiece. As the spindle rotates, the coated abrasive strip that is attached to the spindle rotates too. The rapid rotation of the coated abrasive strip and / or utility cloth helps clean and polish inner diameters and other tight areas
