제품 소개

TCMT insert meaning refers to a triangular-shaped turning insert with a 60-degree included angle (T), a 7-degree clearance angle (C), a medium tolerance class (M), and usually a chipbreaker feature (T).

These inserts offer three cutting edges and a positive rake angle, making them suitable for finishing and semi-finishing operations on smaller workpieces or softer materials.

Their design prioritizes achieving a good surface finish while the chipbreaker ensures effective chip control.

TCMT inserts are a versatile and cost-effective choice for many general-purpose turning applications.

TCMT insert Specification

TCMT meaning:

T: Trigon or triangular shape with a 60-degree included angle.
C: 7-degree clearance angle (creates space between the cutting edge and workpiece).
M: Medium tolerance class (a general-purpose range of precision).
T: Single-side chipbreaker and screw lock.

Following the “TCMT” you’ll see a set of numbers, such as TCMT 21.51 or TCMT 32.52. These numbers tell you the size:

- First number (2 or 3): Indicates the cutting edge length in sixteenths of an inch.
- Number after decimal (1.5 or 2.5): Thickness of the insert in sixteenths of an inch.
- Final number (0, 1, or 2): Nose radius code. A smaller number means a sharper corner, ideal for finishing work.
