American Made Since 1936
For over 80 years, our American-made tool post grinders have operated in machine shops all around the world. While our product has stayed the same, the company has changed over the years. The summer of 2017 marks another change - when Themac LLC took charge of producing the durable grinders in a new facility.
We look forward to continue producing portable tool post grinders that are able to perform difficult grinding jobs on any size lathe. For exclusive design, performance, dependability and adaptability - Themac grinders stand alone.
