ACME solid carbide threading tools are designed for superior durability and precision. Available in both uncoated and coated versions, the AlTiN+ coating offers an enhanced surface finish and extended tool life. The elliptically ground neck ensures maximum strength, providing stability during high-performance machining. With a polished flute face, these tools optimize chip flow and cutting efficiency, reducing wear and improving overall performance. Perfect for high-speed machining and challenging materials, ACME threading tools deliver the reliability and accuracy you need.
