Scg/4714 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.
