Adjustable Mandrel

The Adjustable Mandrel fits all standard sanding bands, arbor bands and Erica's diamond Flip Cylinder. The rubber O-rings allow for cooler cutting and a true secure fit with each band. A slight turn to the left loosens the O-rings making it easy to slide on the sanding band, while a turn to the right contracts the O-rings so that slightly over sized bands will still fit. Right-hand use only.  Optimal use at 6,000-20,000 RPM with an Erica’s ATA electric file. RPM will vary depending on technique, e-file and newness of bit. Standard shank size 3/32” Due to the nature of the products we sell, ALL SALES ARE FINAL.
