Widia 3607827 NTK3R Threading Insert Carbide Altin

Product Description

The WIDIA 3607827 is a carbide threading insert designed for precision thread-cutting operations on both internal and external thread forms. Manufactured to the NTK3R insert style and graded TN6025, this insert features a physical vapor deposition (PVD) AlTiN finish coating that extends tool life in demanding cutting conditions. The included angle is 60 degrees, conforming to UN thread standards, and the corner radius measures 0.003 decimal inches (0.08 mm). It is held in place via a clamp-style insert holding method and is sized as an Insert Size 3. Licensed machinists, CNC operators, and tool and die technicians are the primary installers of this component.

This threading insert is suited for both internal and external threading applications, covering an external pitch range of 0.60 to 2.50 and an internal pitch range of 1.0 to 2.5. It is used in lathe-based or CNC turning center threading operations where a positive chipbreaker geometry is required for controlled chip evacuation. The right-hand cut orientation makes it appropriate for standard right-hand thread production. It is a direct replacement-style insert for setups already configured for the NTK series.

Key Features

• Carbide substrate with PVD-applied AlTiN finish coating for extended tool life
• Covers external pitch range of 0.60 to 2.50 and internal pitch range of 1.0 to 2.5
• 60-degree included angle conforms to UN thread standards
• Positive chipbreaker geometry promotes controlled chip evacuation
• Right-hand cut orientation for standard thread production
• Clamp-style insert holding method for secure, repeatable seating

Compatibility

Designed as an OEM-style replacement threading insert for NTK series toolholders configured for Insert Size 3 and right-hand clamp-style seating in UN thread applications.

Installation Notes

Installation is performed by a qualified machinist or CNC technician. The machine spindle must be fully stopped and the toolholder must be clear of the workpiece before seating or removing the insert. Use the appropriate torx or hex key as specified by the toolholder manufacturer to secure the clamp - do not overtighten. Verify insert orientation and pitch setting against the job specification before resuming cutting operations.
