55 Series HRC55 TiSiN Coated Solid Carbide Ball Nose End Mill | General Milling

The HN55 B2 is a solid carbide ball nose cutter, built for precision 3D contouring and finishing. Available in 2-flute with a 35° helix angle, this tool delivers exceptional rigidity, chip removal, and surface finish quality. Its HRC55 carbide substrate ensures durability in tough machining environments.

Geometry & Benefits

• HRC55 Solid Carbide: Balances toughness and wear resistance—ideal for hardened steels, molds, and die applications.

• 35° Helix: Smooth cutting action with effective chip ejection, enabling high-speed operations with reduced vibration.
  

• TiSN Coating: TiSiN for abrasion control, maximize tool life across different materials.
  

• Full Size Range (Ø1–20 mm, 50–200 mm OL): Ensures flexibility for both fine-detailed work and long-reach cavity machining.
