Kennametal 1799606 Threading Insert KC5025 Carbide Tialn

Product Description

The KENNAMETAL 1799606 is a carbide threading insert designed for cutting American Buttress threads in both internal and external applications. It carries the NTB insert style and belongs to the Top Notch series, a platform engineered for secure, repeatable indexing in threading operations on CNC lathes and turning centers. The insert is coated with TiAlN via a PVD coating process, providing heat resistance and extended tool life when threading ferrous materials. Manufactured to the KC5025 grade, this insert suits material grades C2 and C6. The left-hand configuration and 45-degree included angle are key selection criteria when specifying this part. It is sold individually with a minimum order quantity of 5 units.

This insert is intended for threading operations on American Buttress thread forms at 4 to 6 TPI. The Top Notch series is widely used in production turning environments where insert security and quick changeout are priorities. Both internal and external thread cutting are supported, making this insert applicable across a range of workpiece geometries. Machinists and CNC operators working with ferrous stock in the C2 and C6 material grade range will find this insert appropriate for medium to heavy-duty threading passes. It is a left-hand insert and must be paired with a compatible Top Notch left-hand toolholder.

Key Features

• TiAlN finish applied via PVD process for thermal resistance and wear performance

• American Buttress thread standard, internal and external thread cutting
• Left-hand insert orientation for compatibility with left-hand Top Notch toolholders
• 4 to 6 TPI internal pitch range
• 45-degree included angle with 0.25 mm corner radius for defined thread form geometry

Compatibility

Designed for use with compatible Top Notch series left-hand threading toolholders. Specific toolholder compatibility should be confirmed against KENNAMETAL Top Notch system documentation prior to ordering.

Installation Notes

Threading inserts of this type are installed and serviced by machinists and CNC operators. Power down and lock out the machine spindle before indexing or replacing any insert. Seat the insert firmly in the Top Notch pocket and verify clamp engagement before resuming cutting operations. Confirm toolholder hand orientation matches the insert hand before starting a threading cycle.
