Seco 02636652 Carbide Cutoff Insert 0.161 in TGP45

Product Description

The SECO 02636652 is a solid carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. It carries a CVD-applied Duratomic coating of TiCN and Al2O3, which improves wear resistance and tool life across a broad range of workpiece materials. The insert features a 0.161-inch cutting width, a 0.009-inch corner radius, and a neutral lead angle, making it suitable for straight cutoff passes without side-cutting bias. It is seated and held by a clamp-style toolholder. This insert is sized to the Series 150.10 platform with an insert seat size of 4 and is classified under material grade C5.

This insert is intended for cutoff and parting applications where consistent width tolerance and coating durability are priorities. It is rated for universal primary workpiece materials, giving machinists flexibility across steel, stainless, cast iron, and similar materials. The chipbreaker designation is 16, suited for controlled chip formation during deep cutoff passes. Maximum depth of cut is 3.00 mm. It is a single-end insert, meaning it is indexed out of service when the cutting edge is worn. Typical users are CNC machinists, toolroom operators, and production turning technicians.

Key Features

• Solid carbide construction with CVD Duratomic TiCN and Al2O3 coating for extended wear resistance
• 0.161-inch cutting width with a width tolerance of 0.003 inches for consistent parting results
• Neutral lead angle and neutral hand orientation for straight cutoff geometry
• 0.009-inch corner radius reduces edge stress during entry
• Chipbreaker 16 geometry promotes controlled chip evacuation in parting cuts
• Clamp-held insert seat size 4 for secure, repeatable indexing in compatible toolholders

Compatibility

Designed for use in Series 150.10 clamp-style cutoff and grooving toolholders with an insert seat size of 4. Confirm toolholder seat size and series designation before ordering.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the machine powered down and the spindle locked. Seat the insert fully into the clamp pocket and torque the clamping screw according to the toolholder manufacturer specification. Inspect the insert seat for chips or debris before seating a new insert, as contamination can affect cutting geometry and width accuracy. Follow applicable shop safety procedures and machine guarding requirements during setup.
