Kennametal 1113507 Threading Insert NT2R K68 Carbide

Product Description

The KENNAMETAL 1113507 is a carbide threading insert designed for precision thread-cutting operations on both internal and external threads. Manufactured in the NT2R style with a K68 grade carbide substrate and a bright uncoated finish, this insert produces partial profile 60-degree threads across a wide pitch range. External pitch coverage spans 0.70 to 3.00 mm (8 to 36 TPI), while internal pitch coverage spans 1.25 to 3.50 mm (7 to 20 TPI). With a corner radius of 0.1 mm and a tip-to-top height of 1.91 mm, it delivers consistent thread geometry on a broad range of workpiece materials. It is installed and managed by machinists and CNC operators in production and job-shop environments.

This insert fits threading applications requiring a right-hand cut on both internal and external workpieces. The partial profile 60-degree geometry makes it suitable for general-purpose threading across a range of ferrous and non-ferrous materials matched to the C3 material grade. It belongs to the Top Notch series, which uses a dedicated toolholder and insert retention system common in turning centers and manual lathes. Typical use cases include threading bolts, fittings, couplings, and other cylindrical components where thread form consistency is critical.

Key Features

• Carbide substrate with K68 grade and bright uncoated finish for general-purpose threading
• Partial profile 60-degree included angle for internal and external thread cutting
• External pitch range: 0.70 to 3.00 mm (8 to 36 TPI)
• Internal pitch range: 1.25 to 3.50 mm (7 to 20 TPI)
• Right-hand cut orientation
• Top Notch series insert size 2 for use with compatible Top Notch toolholders

Compatibility

Designed for use with Top Notch series threading toolholders that accept insert size 2. Confirm toolholder seat and clamping style before installation.

Installation Notes

Threading inserts should be installed by a qualified machinist following the toolholder manufacturer torque and clamping procedure. Power down and lock out the machine spindle before seating or replacing any insert. Inspect the insert pocket and clamping screw for wear or debris prior to installation. Do not exceed the recommended depth of cut or feed rate for the insert grade and workpiece material combination.
