Widia 3607823 NTP3R Threading Insert Carbide Altin

Product Description

The WIDIA 3607823 is a carbide threading insert in the NTP series, designed for both internal and external thread cutting on UN-standard threads. Manufactured to grade TN6025 with an AlTiN finish applied via PVD coating process, this insert delivers consistent thread form geometry on a wide range of pitch sizes. The ANSI and ISO code is NTP3R, indicating a right-hand cut orientation and an irregular insert shape secured by a clamp holding method. Licensed machinists and CNC lathe operators use this insert for precision threading operations on lathes and turning centers in production and job-shop environments.

This insert is suited for threading applications requiring a 60-degree included angle on UN-standard threads. The external pitch range covers 1.25 to 4.0 threads per inch, and the internal pitch range covers 2.0 to 5.0 threads per inch. The positive chipbreaker geometry helps control chip flow during threading passes, making it applicable in both light and moderate material removal scenarios. It is used in machining operations across manufacturing, toolroom, and maintenance-repair environments where repeatable thread quality is required.

Key Features

• Carbide substrate with TN6025 manufacturer grade for wear resistance in threading applications
• AlTiN finish via PVD coating process for thermal and oxidation resistance
• Right-hand cut with 60-degree included angle for UN-standard thread form
• Positive chipbreaker design for controlled chip evacuation during threading passes
• Covers external pitch range 1.25 to 4.0 TPI and internal pitch range 2.0 to 5.0 TPI
• Clamp-style insert holding for secure seating in NTP-series toolholders

Compatibility

Designed for use in NTP-series threading toolholders that accept size 3 inserts with clamp-style holding. Compatible with both internal and external threading applications on UN-standard thread forms.

Installation Notes

Threading inserts should be installed by a qualified machinist following the toolholder manufacturer's clamping torque and seat-cleaning procedures. Ensure the machine spindle is fully stopped and the toolholder is secured before seating or replacing the insert. Inspect the insert pocket and clamping screw for wear or debris before installation. Verify thread pitch and hand orientation match the workpiece specification before running a threading cycle.
