6 Flute Solid Carbide Flat Bottom Finishing End Mill for Steel Stainless Mold Making CNC Milling 1/4" to 3/4"

Introduction:

Our premium 6-flute solid carbide flat bottom end mill is engineered for high-precision finishing operations in steel, stainless steel, and mold/die applications. Featuring an advanced micro-grain carbide substrate and precision-ground cutting edges, this industrial-grade tool delivers exceptional surface finishes (Ra < 0.2μm achievable) while maintaining tight tolerances in demanding CNC machining environments.

Features:

• 6-flute design optimized for fine finishing passes

• True flat bottom geometry (±0.005mm tolerance)

• Ultra-fine grain tungsten carbide (Grade K30)

• 45° high helix angle for smooth chip evacuation

• Optional AlTiN or TiSiN coatings available

• Precision ground cutting edges with minimal runout (<0.003mm)

• Available in 1/4" to 3/4" diameters (6-19mm)

Advantages Over Competitors

✓ Produces mirror-like surface finishes
✓ 30% longer tool life compared to 4-flute end mills
✓ Reduced vibration through balanced flute design
✓ Higher feed rates enabled by multi-flute configuration
✓ Excellent wear resistance in hardened steels (up to HRC 55)

Typical Applications

• • Precision finishing of mold/die surfaces (P20, H13)

  • Final passes on stainless steel components (304, 316)

  • High-tolerance machining of alloy steels (4140, 4340)

  • Aerospace structural part finishing

  • Medical device component machining

  • General CNC milling requiring superior surface quality
