DCMT insert specification
DCMT insert meaning a diamond-shaped (55 degrees), indexable cutting insert with a 7-degree clearance angle, moderate tolerances, and a built-in chipbreaker.
These inserts are commonly used for various turning operations in metalworking.
The nose radius has crucial effects on the surface finish, chip breaking, and insert strength.
We offer several different nose radius selections to help to enhance working quality. Generally speaking, Small nose radius will lead to small cutting depth, reduce vibration and enhance chip breaking.
On the other side, the large nose radius will be suitable for high feed rate, large depths of cut, and strong edge stability.
The relationship between nose radius and depth of cut affects vibration tendencies.

DCMT insert Meaning
Understanding the DCMT Insert Code
- D: Shape: Rhombic (diamond) with a 55-degree included angle.
- C: Clearance Angle: 7 degrees (positive)
- M: Tolerance: Medium tolerance is standard, though other precision tolerances might be available.
- T: Chipbreaker style & Hole Configuration. This letter designates the specific chipbreaker geometry and whether the insert has a hole or not. Chipbreaker variations are numerous and manufacturer-specific.
- Sayısal basamaklar:
- First Two Digits: Inscribed circle (IC) diameter in millimeters. To obtain the approximate inch equivalent, divide this number by 25.4.
- Next Two Digits: Thickness in millimeters. Divide by 25.4 to convert to inches.
- Last Two Digits: Nose radius in millimeters. To convert to inches, divide by 25.4.
