4 Flute Solid Carbide End Mill with Nano Bronze Coating For Hard Materials HRC60 CNC Milling 1/8" to 1/2"

Introduction:

Our premium 4-flute solid carbide end mill features an advanced Nano Bronze coating specifically engineered for machining ultra-hard materials up to HRC 60+. This industrial-grade cutting tool combines exceptional heat resistance with reduced friction properties, making it ideal for demanding applications in aerospace, mold/die, and medical manufacturing. The optimized flute geometry ensures superior chip evacuation even in the toughest alloys.

Features:

• 4-flute design balances material removal rate and finish quality

• Proprietary Nano Bronze coating (TiAlN+Cu composite)

• Ultra-fine grain carbide substrate (Grade K10)

• Precision ground cutting edges (±0.005mm tolerance)

• 35° helix angle for reduced cutting forces

• Center cutting capability

• Available in 1/8" to 1/2" diameters (3-12mm)

Advantages Over Competitors

✓ 40% longer tool life vs. standard TiAlN coatings
✓ Maintains hardness at temperatures exceeding 900°C
✓ Reduced built-up edge in gummy alloys
✓ Higher feed rates enabled by efficient chip clearance
✓ Consistent performance in interrupted cuts.

Typical Applications

• Hardened tool steels (D2, H13, M2)

• Titanium alloys (Grade 5, Grade 23)

• Nickel-based superalloys (Inconel 718, Waspaloy)

• High-temperature aerospace components

• Medical implant machining

• Die/mold core/cavity work
