The Sherline milling vise is sized just right to be the perfect working companion to the Sherline milling machine. The jaws are 2.00" (50.8mm) wide by 1.00" (25.4mm) deep and open a full 2.00" (50.8mm). The fixed jaw has both a horizontal and vertical "V" groove to facilitate holding round bar stock. The vise includes two clamps for use in attaching it to the milling machine. These clamps are the same as the 4-jaw hold-down set (P/N 3058).
