The BIG Tap

We recently received a donation of a BIG tap manufactured for Westinghouse by Vermont Tap and Die in Lyndonville Vermont.

Vermont Tap and Die was purchased by Vermont American in 1957, and then by Harbour Group in 1991. Harbour Group had formerly purchased Greenfield Tap and Die in 1986. In 1997 Kennametal purchased Greenfield Industries and Vermont American from Harbour Group. The Lyndonville plant was closed by Kennametal in March 2014 and some operations were moved to Greenfield.

This tap weighs over 200 pounds and is made of high speed steel. It was designed to be driven by a machine and not by hand.
