    Model 212B Miter Mandrel Head for SP/FF OPERATION CAUTION: Never attempt to manually lift the Miter Mandrel Head with the 212B installed. The eight (8) Jackscrews are removable. They are made of heat-treated steel and have a slight spherical radius on the surface that contacts the work-piece. On most surfaces, this provides for excellent holding power with virtually no marring of the work-piece.
  • Page 12 TRI TOOL INC. The Extension Plate helps stabilize the miter mandrel head on the extended ID Ranges. It mounts to the front of the miter mandrel head (P/N 21-0101). Turn the Jackscrews to a diameter slightly smaller than the bore of the work-piece.
