Adjustable Angle Toolholder

Abstract

An adjustable angle toolholder comprising a shank and an adjustable head is provided. The shank has a first end and a second end. The first end is adapted to be held in a machine, such as a lathe. The second end includes a fixed plane oriented parallel to a lengthwise direction of the shank. The fixed plane includes an arcuate face at a distal end of the fixed plane. The head has a fixed plane that mates with the fixed plane of the shank. The fixed planes of the shank and head include a pivot hole through which a pivot bolt passes. The pivot bolt allows adjustment of the head through a wide range of angles relative to a lengthwise direction of the shank, while the fixed planes maintain a position of a centerline of a cutting tool constant with respect to a centerline of the shank. The fixed plane of the shank may be on a centerline of the shank.
