SER2020K16 External Threading Tool Holder for ER16 Inserts

The SER2020K16 is a precision external threading tool holder designed to provide rigidity, accuracy, and versatility in CNC and conventional lathe operations. With a square shank size of 20×20 mm and a length of approximately 125 mm, it offers a stable platform for high-quality thread turning. This holder is designed for ER16 threading inserts, which cover a wide variety of thread profiles including metric, UNC, UNF, and Whitworth, making it suitable for many different threading applications.

The screw-locking system ensures that the ER16 insert is clamped securely, minimizing insert movement under cutting loads. This results in precise and repeatable thread profiles, even in demanding conditions. The right-hand cutting orientation and 95° approach angle make the SER2020K16 ideal for external threading on cylindrical workpieces, ensuring smooth chip flow and consistent thread quality.

Constructed from hardened alloy steel, the tool holder is durable and resistant to wear, offering long service life even when machining tougher materials like alloy steels and stainless steels. Its robust build ensures minimal vibration and high rigidity, allowing machinists to produce accurate threads with excellent surface finish.

The SER2020K16 combines strength, precision, and flexibility, making it a go-to choice for workshops and production facilities where threading reliability and accuracy are critical. With its compatibility with widely available ER16 inserts and dependable clamping system, this holder enhances efficiency and ensures consistent performance in threading operations.
