Trautman Expansion Arbors From Fillauer
June 26, 2017
Fillauer's Trautman Expansion Arbors are designed to prevent the sanding cone from flying away. When the expansion arbor spins, it expands and applies pressure to the inside of the sanding sleeve— holding the sleeve on the arbor.
Features and benefits include:
Provides a smoother grinding surface for straighter lines and a higher quality finish
Eliminates grinding chatter that grinding hard surfaces yields
Available in three sizes and as a kit of three
Available in 1/2-13, 5/8-11, and M16 threads to fit most O&P machinery
