Widia 3607852 Threading Insert NTF2R TN6025 Carbide

Product Description

The WIDIA 3607852 is a carbide threading insert in the NTF series, designed for cutting both internal and external UN threads on CNC lathes and threading machines. The insert carries a TN6025 grade carbide substrate with an AlTiN finish applied via PVD coating, which provides a hard, heat-resistant surface layer suited for threading ferrous and hardened materials. It is a right-hand insert with a 60-degree included angle and a flat chipbreaker geometry. The corner radius measures 0.003 inches, and the insert thickness is 0.219 inches. This insert is installed by machinists and CNC turning specialists performing precision thread-form operations.

The 3607852 is used in threading operations on CNC lathes, turning centers, and dedicated threading machines. It handles external thread pitches from 0.60 to 1.75 threads per inch and internal thread pitches from 1.0 to 2.0 threads per inch to the UN thread standard. The NTF insert style and size 2 form factor are suited for both production and job-shop environments where consistent thread quality is required. Coolant-through capability is not supported on this insert.

Key Features

• Carbide substrate with TN6025 grade for wear resistance in threading applications
• AlTiN finish applied by PVD coating for elevated heat resistance
• Right-hand cutting geometry with 60-degree included angle for UN thread forms
• Covers external pitch range of 0.60 to 1.75 TPI and internal pitch range of 1.0 to 2.0 TPI
• Flat chipbreaker design for predictable chip control during threading passes
• Clamp-style insert holding method for secure seating in compatible toolholders

Compatibility

Designed for use in NTF-series threading toolholders that accept a size 2 insert with clamp-style retention. Verify toolholder pocket specifications before installation to confirm fit.

Installation Notes

Threading inserts of this type are installed by machinists or CNC tooling specialists. Power down and lock out the machine spindle before changing inserts. Use the appropriate torque wrench or clamp screw driver specified by the toolholder manufacturer when securing the clamp; do not over-tighten. Inspect the insert pocket and clamp for chips or debris before seating the new insert to ensure proper indexing and surface contact.
