40 TOOTH MODULE 1 GEAR

This is a metric module 1 change gear used on Shoptask / Shopmaster machines as well as in most all Chinese and European lathes and other equipment. It has the 4 spline center hole which offers good contact and support, while making it easy to change out for different ratios.
