3/16 × 1 1/2 × 1/4 (3 1/2" OAL) ظرف سنبلة B-2

Bought two of these to run 1 1/2" cartridge rolls in my die grinder and they hold up great. The 1/4" pilot keeps the roll centered so I get even wear instead of burning one edge. Ran through a whole batch of welds without the mandrel slipping once.

Snug fit on the 3/16" shank with no wobble at all, which matters when I'm running cartridge rolls on tighter inside corners. The piloted end keeps the roll centered so I get even wear instead of one side loading up.

The 1 1/2" roll length is exactly what I needed for getting into the tight corners on my welding projects. The shank locks down solid in the collet with zero wobble, which makes a huge difference when you're trying to be precise.
