A8,1/8X3/4X1/4 CARTRIDGE ROLL MANDRELA8,1/8X3/4X1/4 CARTRIDGE ROLL MANDREL 50108 These Cartridge Roll Mandrels are used for abrasive cartridge rolls or tootsie rolls as they are sometimes called. They have either 1/8" or 1/4" shank and the pilot hole diameter should match the hole diameter in your cartridge roll. Then the pilot length should be "ONE" size smaller than the cartridge roll length! Thus a 3/4" long roll should use a 1/2" piloted arbor, 1" to use a 3/4", 1-1/2" to use a 1", 2" to use a 1-1/2 and so forth! Any questions, salesperson!
