مغزل خرطوشة 1/4 × 2 × 1/4 (4" OAL) C-3

This mandrel feels solid, the 1/4" shaft fits my setup perfectly. I've used it with a few different cartridge rolls now and it holds them tight with no slippage.

These cartridge mandrels are exactly what I needed for my drum sander setup. The 4-inch overall length gives me plenty of reach for tight spaces, and the C-3 grade holds the abrasive securely without any wobble.

The C-3 fits snugly on my drill and the 4" OAL gives me just the reach I needed for a tight spot. Cartridge mandrels can be finicky, but this one’s held up through a dozen sanding sessions without any wobble.
