GC - Ball Nose Reduced Neck End Mills - For Mold Steel - 2-Flutes

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 Reduced Neck structure prevents tool interference, making it suitable for deep cavity and complex surface machining, ensuring smoother operations.

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
