The CLE-LINE C66718 is a two-piece adjustable threading die designed to cut 3/4-16 UNF (Unified Fine) external threads. The two-piece construction allows the die to be adjusted for thread fit, making it suitable for both roughing and finishing passes in a single tool. Built from carbon steel, this die is intended for threading operations on standard ferrous and non-ferrous workpieces. It fits Collet 5 die stocks and handles. Machinists, pipefitters, and maintenance technicians working with 3/4-16 UNF fastener threads are the primary users of this tool.
This die is used in shop, maintenance, and field threading applications where 3/4-16 UNF external threads need to be cut or restored. The adjustable design provides flexibility for controlled thread tolerance, making it appropriate for both production runs and one-off repair work. It is sized for Collet 5 die stocks, which are standard holders for round adjustable dies in this size range.
Designed for use with Collet 5 round adjustable die stocks. Cuts 3/4-16 UNF external threads per the Unified Fine Thread Standard.
Threading dies should be installed in a properly sized die stock before use. Secure the workpiece firmly before beginning the threading pass, and apply cutting oil to extend die life and improve thread quality. Inspect the die for wear or damage before each use. Adjustment screws on the die stock should be used to set the two-piece die to the desired thread tolerance before cutting.
