TCGT Inserts are precision triangular carbide inserts with a 60° included angle and a positive rake geometry. The “TCGT” designation comes from the ISO insert coding system:

• T = Triangle (60° shape)

• C = Clearance angle (7°)

• G = Tolerance (high precision, ground edges)

• T = Insert type (with hole, single-sided positive rake)

These inserts are widely used in finishing operations, delivering excellent surface quality with minimal cutting forces.

⚙️ Applications of TCGT Inserts

TCGT inserts are highly versatile and commonly used in:

• Finishing on CNC lathes – Producing smooth surfaces.

• Machining Non-Ferrous Materials – Aluminum, copper, brass, and plastics.

• Stainless Steel Machining – With PVD coatings, excellent for stainless.

• Light to Medium Cutting – Low cutting forces due to sharp cutting edges.

• Profiling & Contouring – Suitable for complex geometries.

🔍 Types of TCGT Inserts

Different variations of TCGT inserts are available depending on edge prep and coatings:

1. Uncoated Polished TCGT Inserts – Best for aluminum and non-ferrous materials.

2. PVD-Coated TCGT Inserts – Designed for stainless steel and titanium.

3. CVD-Coated TCGT Inserts – Used for steels and cast iron.

4. Different Nose Radii –

   • 0.2mm & 0.4mm → Finishing.

   • 0.8mm & 1.2mm → Roughing and higher feed operations.
