Heavy Duty 12mm 4 Flute Carbide End Mill For Steel Stainless 17-4PH CNC Cutting

Heavy Duty 12mm 4 Flute Carbide End Mill For Steel Stainless 17-4PH CNC Cutting

Introduction:

The 12mm 4-Flute Carbide End Mill is an industrial-grade cutting tool designed for high-performance machining of tough materials including stainless steel (17-4PH), tool steels, and alloy steels. Built from ultra-fine grain tungsten carbide (YG10X) and featuring an optimized 4-flute geometry, this end mill delivers exceptional metal removal rates (MRR), tool life, and surface finish quality in demanding CNC applications.

Features:

✔ Industrial Carbide Construction (YG10X Grade)

• Sub-micron grain structure for maximum edge retention

• 5-8X longer life vs. HSS end mills

• Withstands high cutting temperatures without deformation

✔ 4-Flute High-Efficiency Design

• Balanced chip load for stable cutting in steels

• Variable helix (35°/40°) reduces vibration & harmonics

• Large core diameter for rigidity in heavy cuts

✔ Premium Coating Options (Optional)

• AlTiN Coated Version available for HRC≤55 materials

• TiSiN Nano-Coated Version for gummy stainless steels

• Uncoated for general purpose applications

✔ CNC-Optimized Performance

• Precision ground to ±0.008mm tolerances

• G2.5 dynamically balanced for 15,000+ RPM

• Coolant-through capability (optional)

✔ Flat Bottom & Corner Radius Options

• True flat bottom for shoulder milling

• R0.5 corner radius available for edge strengthening

Advantages:

✅ Higher Productivity - 30% faster feed rates vs. 3-flute designs

✅ Superior Finish - Ra 0.4-0.8μm achievable in finishing passes

✅ Vibration Damping - Variable helix eliminates chatter marks

✅ Deep Cutting Capable - Stable performance at 2.5xD depth

✅ Cost Efficiency - Reduced tool changes lower per-part cost

Applications:

Materials:

• Stainless Steels: 17-4PH, 304, 316

• Tool Steels: D2, H13, A2 (HRC≤55)

• Alloy Steels: 4140, 4340

• High-Temp Alloys: Inconel 718, Waspaloy
