Groz Screw Cutting Gauge
• Manufactured from hardened and polished stainless steel, all gauge surfaces are accurately ground.
• It is most useful for checking tool angle while cutting threads in metal turning lathes. The angle on the thread cutting tool is checked on the V slots in the gauge.
• Relief at the end of each slot enables proper seating of the cutting tool in the slot thus ensuring correct angle.
• The gauge clearly indicates 55° for Whitworth and BSF Threads; 47-1/2° for BA Threads, 60° for Metric and American National • Threads and 14-1/2° for Acme threads.
