Collection: Mandrels for Abrasive Cartridge Rolls

Hardened steel mandrel firmly secures abrasive cartridge rolls.

For proper fit, arbor hole of cartridge roll = pilot diameter of mandrel.
For example, a cartridge roll with an arbor hole (AH) of 5/64" would require the A1 mandrel which has a 5/64" pilot diameter. More flexibility may be obtained if pilot length is slightly shorter than the cartridge roll. If necessary, mandrel may be ground down to needed length.

Mandrels have 1/8" or 1/4" shank for your flex shaft or other rotary handpiece.
