TPKN insert

TPKN insert is another type of cutting insert used in machining operations, particularly in turning and milling.

TPKN Insert Specification Guide

T: This usually refers to the shape of the insert. In this case, ‘T’ typically stands for “Triangle” shape.
P: Often indicates a specific angle or clearance feature of the insert. In many cases, it denotes a positive rake angle.
K: This could refer to the insert’s tolerance class or a specific feature of the cutting edge.
N: Might indicate the absence of a chip breaker or a particular nose radius.

TPKN Insert Cutter Compatibility

TPKN inserts are generally known for their versatility and are often used in both turning and milling operations. The triangular shape provides three cutting edges, allowing for extended use before replacement is necessary. These inserts are often favored for their ability to handle a variety of cutting conditions and materials.

These inserts are typically used in operations requiring good chip control and surface finish, and they’re often suitable for machining steel, stainless steel, and cast iron, among other materials.

Applications

Inserts excel in various industrial milling operations:

General face milling
Shoulder milling
Roughing and finishing operations
Suitable for materials including steel, stainless steel, and cast iron
