Dual Purpose Expansion Arbors
July 01, 2020
Fillauer's Expansion Arbors expand while in use to apply inside pressure to the sanding sleeve to hold it in place. These tools prevent migration and "fly away" of the sanding sleeve and provide a smoother grinding surface for straighter lines and higher-quality finish. Available in ½-13, ⅝-11, and M16 threads to fit most O&P machinery.
