Trautman Expansion Arbors From Fillauer

Home > Product Showcases > Trautman Expansion Arbors From Fillauer

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
