Product Overview: Tungsten Carbide Micro-Diameter Ball Nose End Mill – MSB Series

【Product Features & Why We Recommend It】

• Taiwan Brand Professional Manufacturing: Originating from a professional Taiwanese cutting tool brand with strict quality control — recommended for users requiring micro-diameter precision machining with high demands on dimensional accuracy and tool consistency.
• G12 Coating Enhancement: The cutting edges are treated with G12 coating, providing outstanding wear resistance and heat resistance — effectively extending tool life under the high-speed spindle conditions typical of micro-diameter machining.
• Micro-Diameter Ball Nose Design: The ball nose geometry accurately conforms to 3D curved surface profiles and mold cavity arc floors — recommended for fine detail finishing and high-precision forming operations, making it an essential choice for micro-scale features.
• Compact Specification Full Coverage: Available in ball nose radius R0.15–1.5mm, flute length 0.6–6mm, overall length 50mm, and 2-flute configuration — recommended for flexible selection based on feature size and surface complexity.

【Machining Applications & Uses】

• Primary Use: 3D curved surface finish machining, mold cavity machining, arc floor profiling, and micro-feature detail milling.
• Recommended Work Materials:
  • P-Class (Carbon Steel / Alloy Steel): Structural steel, carbon steel, and alloy steel within HRC60 — delivering stable micro-diameter cutting performance.
  • H-Class (Hardened Steel): Quenched steel and high-hardness mold steel — the most advantageous application scenario for this series, with G12 coating effectively resisting wear during high-hardness machining.
  • K-Class (Cast Iron): Provides stable and consistent wear-resistant tool life for cast iron materials.
