Sharp tap from machine shop inventory. Labeled as HSS-E, indicating a cobalt steel. The tube original to the tap suggests that this was manufactured in West Germany. Most likely used, but all flutes and teeth appear sharp with no chipping. Please reach out with any questions. I am happy to clarify or provide additional info concerning any item. I will consider all reasonable offers, and can offer additional discounts when purchasing multiple items from my store / seller page. Thanks for looking!
