CCMT inserts feature a 7° clearance angle, reducing friction and ensuring smooth surface quality.
Versatile Cutting Applications
From steel and stainless steel to non-ferrous metals, CCMT inserts offer excellent adaptability.
Economical Cutting Solution
Multi-edged inserts reduce tooling costs, as each insert can be indexed several times before replacement.
Stable Performance
Their precise geometry guarantees consistent chip control and minimizes vibration, even in high-precision CNC turning.
2. Decoding the CCMT Nomenclature
Each letter and number in CCMT060202, CCMT09T304, and CCMT120404 follows the ISO insert designation system.
CCMT
C = Shape: 80° rhombic diamond – a strong and versatile geometry.
C = Relief angle: 7° clearance for reduced cutting forces.
M = Tolerance class: Medium precision, suitable for general to precision turning.
T = Insert type: Single-sided insert with hole for screw clamping.
Numerical Codes
CCMT060202
06 = Cutting edge length (~6.35 mm).
02 = Insert thickness (~2.38 mm).
02 = Nose radius (0.2 mm) → Excellent for fine finishing.
CCMT09T304
09 = Cutting edge length (~9.52 mm).
T3 = Insert thickness (~3.97 mm).
04 = Nose radius (0.4 mm) → Ideal for finishing and semi-finishing.
CCMT120404
12 = Cutting edge length (~12.7 mm).
04 = Insert thickness (~4.76 mm).
04 = Nose radius (0.4 mm) → Stronger edge for medium cutting.
