مغزل خرطوشة A-3 مقاس 1/8 × 2 × 1/4 (طول إجمالي 4 بوصات)

The 3/8" arbor fits my bench grinder perfectly, and the 2-inch wheel depth gives me great control for deburring. The 1/4" thickness is just right for smoothing out welds without bogging down the motor.

Finally found a mandrel that doesn't wobble in my rotary tool—the 4-inch overall length gives me just the right reach for sanding inside tight curves.

This mandrel fits perfectly on my 1/8" arbor and the 4" overall length gives me just the right reach for my sanding drum setup. The 2" working surface holds the cartridge firmly without slipping. Happy with the clean machining on the threads, makes for a wobble-free run.
