2 Flute Solid Carbide Flat Bottom End Mill Deep Groove Milling Cutter for Steel Stainless Alloy Steel CNC Machining

Introduction:

Our 2-flute solid carbide flat bottom end mill features a specialized deep groove design engineered for high-performance machining of steel, stainless steel, and alloy steels. Manufactured from premium micro-grain tungsten carbide, this industrial-grade cutting tool delivers exceptional metal removal rates while maintaining precision in deep slotting and pocketing operations. The optimized flute geometry provides superior chip evacuation, making it ideal for demanding CNC machining applications.

Features:

• • 2-flute design for efficient chip clearance in steel alloys

  • True flat bottom geometry (±0.01mm) for precise shoulder milling

  • Deep groove flute design prevents chip packing in deep cavities

  • Ultra-fine grain carbide substrate (Grade K40) for maximum wear resistance

  • Precision ground cutting edges with sharp corner radii (R0.1-R0.5 options)

  • Available with TiAlN, AlCrN or uncoated variants

  • Standard diameters: 3mm-20mm (1/8" to 3/4")

Advantages Over Competitors

✓ 40% faster feed rates compared to 4-flute end mills in steel
✓ Excellent stability in deep slot machining (up to 5xD depth)
✓ Reduced vibration through optimized helix angle (35°)
✓ Extended tool life - 3X longer than HSS tools in stainless steel
✓ Superior surface finish (Ra 0.3-0.8μm achievable)

Typical Applications

• • • • • • Heavy-duty slotting in carbon steels (AISI 1045, 4140)

          • Deep cavity machining in mold/die steels (P20, H13)

          • Stainless steel (303, 304, 316) component manufacturing

          • Alloy steel (4340, 6150) aerospace parts

          • General CNC milling of ferrous materials
