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 4-flute square geometry is ideal for slotting, side milling, and cavity machining. Ensures stable cutting performance, dimensional accuracy, and efficient material removal.
Substrate & Coating
- Substrate: Ultrafine-grain carbide with a balanced combination of high hardness and toughness.
- Coating: TiAlSiN nanocomposite coating — high surface hardness, excellent wear and high-temperature oxidation resistance, effectively extending tool life.
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 and toughness
- Optimized 4-flute geometry for stable chip evacuation and reduced cutting forces in side milling and slotting
