The Groz Screw Cutting Gauge is an indispensable tool for machinists and metalworkers. Made from high-quality, hardened and polished stainless steel, this gauge provides a durable and reliable tool for thread cutting. With accurate ground surfaces, this gauge makes it easy to check tool angle when cutting threads in metal turning lathes. The V slots on the gauge provide a convenient way to check the angle of the thread-cutting tool and the relief at the end of each slot ensures proper seating of the tool for an accurate cut.
