55 series- HRC55 Solid Carbide Ball Nose End Mill TiSiN Coated

The HN55 B2 is a premium solid carbide ball nose cutter, built for precision 3D contouring and finishing. Available in both 2-flute and 4-flute variants 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, and the wide array of high-performance coating options allows you to tailor performance to your material and application needs.

Geometry & Benefits

• 2-Flute & 4-Flute Options: Choose broader flute space for aluminum and non-ferrous materials (2F), or enhanced rigidity and stability for steel and hard materials (4F).
  

• 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.
  

• Varied Coatings: Customizable options—such as AlTiN for heat resistance, TiSiN for abrasion control, DLC for low friction, etc.—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.
