Overview
GC Series Plastic Mold End Mills Crafted for semi-finishing and finishing of plastic mold steels. Made from ultra-fine grain carbide with TiAlSiN coating, these end mills deliver stable cutting, excellent wear resistance, and long tool life.
The 2-flute ball nose geometry is ideal for 3D contouring, complex surface finishing and high-quality surface profiling of mold cavities.
Substrate & Coating
- Substrate: Ultrafine-grain carbide
- Coating: TiAlSiN nanocomposite coating — delivers high hardness, wear and oxidation resistance for fine finishing tasks.
Cooling Recommendation
Optimized for air cooling or Minimum Quantity Lubrication (MQL); use flood coolant for heavy cuts. Dry cutting possible for short passes but not recommended long term.
Cutting Capability
- Workpiece Hardness: ≤ HRC48
- Typical Materials: P20 / 1.2311, 718 / 1.2738, 718H, NAK80, 4Cr13H, S136, 1.2085
- Note: Not suitable for hardened steels exceeding HRC48 after heat treatment.
Edge & Flute Design
- Edge honing to improve chipping resistance at the ball tip
- Optimized 2-flute geometry for efficient chip evacuation in deep or contoured pockets and to reduce cutting load at the ball center
