Used in horizontal and vertical machining centers requiring large-diameter boring and automatic facing operations, the Criterion Series F Automatic Boring and Facing Head is a premium USA-made unit engineered for precision work at larger bore diameters. Measuring 44" x 7" x 7", the facing and boring mechanism operates automatically during the cutting cycle, allowing the tool to advance radially on each spindle pass, enabling face turning, back facing, and grooving operations without manual intervention. Criterion identifies this head as Series F, manufactured in the USA, consistent with their FC-34 and FC-44 series application range and the 3F-HB automatic boring and facing head family. The head body features a bronze-colored facing ring and a hardened steel body with a machined dovetail for the tool slide. Criterion is a long-established American tooling brand, now part of Allied Machine and Engineering, known for precision-ground boring heads manufactured to tight dimensional standards. The serial number 20988 is visible on the shank body.
