Iscar 3800225 Modular Threading Head C4 50mm Right Hand

Product Description

The ISCAR 3800225 is a Size C4 external modular threading cutting unit head engineered for precision thread-turning operations on CNC lathes and turning centers. Part of the IscarThread series, this right-hand cutting head accepts a wide range of screw-locked ER and GT insert styles, giving machinists flexibility across multiple thread profiles without changing the toolholder body. The head measures 3.54 inches in length with a 1.97 x 1.97 inch cross-section, and weighs 0.86 pounds. The center-to-cutting-edge distance is 27 mm, and the head length is 50 mm. Designed to ISO 13399 standards, this unit delivers consistent insert positioning and repeatable tool offsets across setups.

This threading head is suited for external threading applications on ferrous and non-ferrous materials in both production and job-shop environments. The modular design allows the C4 head to mount on compatible IscarThread shanks and adapters, making it practical for shops running multiple thread forms. It is typically installed by machinists and CNC setup technicians on turning equipment requiring frequent insert or profile changes.

Key Features

• Right-hand external threading orientation for standard OD thread-turning
• Size C4 modular interface for use with compatible IscarThread shanks
• Screw-type insert holding method for secure, repeatable seating
• Compatible with a broad range of ER and GT insert styles covering UN, NPT, NPTF, BSPT, ISO, ACME, API RD, and additional thread profiles
• Conforms to ISO 13399 tooling data standards for integration with CAM and presetting systems
• 50 mm head length with 27 mm center-to-cutting-edge distance for defined reach geometry

Compatibility

Compatible insert styles include ER-MJ, ER-NPTF, ER-PG, ER/L-55, ER/L-60, ER/L-ABUT, ER/L-ACME, ER/L-API RD, ER/L-BSPT, ER/L-ISO, ER/L-NPT, ER/L-RND, ER/L-SAGE, ER/L-STACME, ER/L-TR, ER/L-UN, ER/L-UNJ, ER/L-W, GTGA, and GTMA. This head is part of the IscarThread modular system and is designed for use with compatible C4 interface shanks and adapters.

Installation Notes

Installation should be performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before mounting or removing any modular tooling components. Use the correct torque wrench and manufacturer-specified clamping screws when securing inserts to avoid insert movement during cut. Verify tool offset and reach geometry at the presetter or with a test cut before committing to production.
