Product Overview
Even Cut FULL-TAPERED-60 (catalog 30956) is a full-tapered cartridge roll made from resin-bonded aluminum oxide abrasive cloth. Designed for high-speed rotary tools and die grinders, it mounts to a standard 1/8-inch pilot mandrel to reach tight radii, recessed channels, and complex internal contours. As the outer layers wear down during grinding, they expose fresh abrasive grain, maintaining consistent cutting action across the life of the roll.

Frequently Asked Questions
What mounting hardware is needed to use this cartridge roll?
This roll requires a standard 1/8-inch pilot mandrel sized for 1-1/2-inch long cartridge rolls. The pilot rod inserts into the center arbor hole and secures into a die grinder or rotary tool collet.
How does a tapered cartridge roll wear during use?
The roll is wrapped in successive spiral layers. As the outermost layer wears down from friction, the backing cloth frays away to continuously expose fresh aluminum oxide grit underneath until the roll is fully consumed.
How does a full taper differ from a straight or half-taper cartridge roll?
A full-taper roll narrows continuously from its 1/2-inch base down to the tip, allowing access into sharp angles and tapered channels where a cylindrical roll will not clear. Quantity pricing applies: the price-break table on this page shows the price per piece at every step.
Cartridge rolls are built to sacrifice themselves layer by layer so your finished metal does not have to. Chuck it onto an eighth-inch pilot and blend out that stubborn inside corner.
