Kennametal 1113510 Threading Insert K68 Carbide Top Notch

Product Description

The KENNAMETAL 1113510 is a carbide threading insert in the Top Notch series, designed for cutting both internal and external threads on CNC lathes and manual turning centers. Built to an NTP2L insert style with a K68 manufacturer grade and C3 material grade, this uncoated carbide insert covers a partial profile 60-degree thread form. It handles external pitches from 0.70 to 3.00 mm (8 to 36 TPI) and internal pitches from 1.25 to 3.50 mm (7 to 20 TPI). The left-hand configuration suits specialized threading operations where conventional right-hand inserts cannot be applied. Machinists and CNC operators in metalworking shops install this insert into compatible Top Notch toolholders for high-accuracy thread generation.

This insert is used in general machining environments where 60-degree unified or metric thread forms are required. Its uncoated bright finish makes it well suited for non-ferrous metals and materials where coated grades may not be preferred. The partial profile design allows a single insert to cut a range of thread pitches without requiring a dedicated insert per pitch, reducing tooling inventory. It is appropriate for both production and job-shop threading applications on lathes equipped with Top Notch series toolholders.

Key Features

• Uncoated K68 carbide grade with C3 material classification for threading non-ferrous and general-purpose workpieces
• Partial profile 60-degree thread form covers a broad pitch range in a single insert
• Left-hand insert hand for reverse-direction or specialized threading setups
• 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)
• Top Notch series platform for secure, repeatable seating in compatible toolholders

Compatibility

Designed for use with KENNAMETAL Top Notch series threading toolholders that accept NTP2L style inserts with an insert size 2 designation.

Installation Notes

This insert is installed and replaced by qualified machinists or CNC tooling technicians. Always power down and lock out the lathe spindle before changing inserts. Use the correct torque wrench and clamping screw specified for the Top Notch toolholder to ensure proper seating and prevent insert movement during cutting. Inspect the toolholder pocket for chips or debris before seating the new insert, as contamination in the pocket can cause premature edge failure or poor thread accuracy.
