Vermont Gage Metalworking Industry

Vermont Gage Metalworking Industry was through manufacturing knock-out pins, ejector pins, perforators, special punches and virtually any precision round and ground pins used by a variety of cutting tool blank users.

About Vermont Gage Metalworking Industry

Since the inception, VPT has expanded its product offering to also include core rods and medical burr blanks. We now service over 1,500 customers.

With our experience in precision grinding VPT created a Gage division to manufacture a wide range of gage pins and sets. Vermont Gage was formed in 1980.  In 1989, the gage line expanded to include all classes of tolerances. Additionally, we have expanded the types of gages offered to our customers by adding taperlock gages, ring gages, and thread ring gages.

In 2000, we opened our thread manufacturing division in a state of the art manufacturing facility in Franklin, Kentucky.   We have expanded this operation a number of times as the demand for our thread product has risen year over year.

Vermont Gage’s success has been built on quality products, competitive price and delivery, technical expertise and exceptional customer service.
