Violet ★★★★★

The 3/16 shank fits my die grinder perfectly and the 1/4 roll width is exactly what I needed for cleaning up those tight slots. Screwed it in, popped on a cartridge, and it ran true with no wobble right out of the box.

Penelope M. ★★★★★

The 6-inch overall length gives me plenty of reach into deeper bores without sacrificing stability. It fits my cartridge rolls snugly and spins true on the first try.

Scarlett T. ★★★★★

I needed a mandrel for some tight cartridge roll work and the 3/16 shaft on this B-4 fit my die grinder perfectly. The 1-1/2 inch length on the roll area gives me enough reach without being floppy. No wobble at all when I spun it up.
