ماسورة كارتريدج C-2 1/4 × 1 1/2 × 1/4 (طول إجمالي 3 1/2 بوصة)

The 3.5-inch overall length is perfect for reaching into tight spots without swapping tools, and the 1/4-inch shank fits my rotary tool snugly with zero wobble. I've run it through a dozen sanding sleeves so far and the threads still engage cleanly every time.

Been using this on my grinder for deburring metal edges and the mandrel holds the sanding sleeve tight without slipping. The 3 1/2 inch overall length gives it a nice reach into awkward spots.

It fit perfectly on my drill press for sanding the inside of a small metal ring I was polishing. The 1/4-inch shank held tight without any wobble during use.
