Industrial-Grade Cutting Performance

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

Key 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: AlTiN coated version 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

Performance Advantages

30% faster feed rates vs. 3-flute designs

Superior finish with Ra 0.4-0.8μm achievable

Variable helix eliminates chatter marks

Stable performance at 2.5xD depth

Reduced tool changes lower per-part cost

Applications

Materials: Stainless Steels (17-4PH, 304, 316), Tool Steels (D2, H13, A2), Alloy Steels (4140, 4340), High-Temp Alloys (Inconel 718, Waspaloy)

Industries: Aerospace (structural components, landing gear), Medical (surgical instruments, implants), Oil & Gas (valve bodies, wellhead components), Mold & Die (core/cavity machining)

Operations: Shoulder milling, Pocketing, Contouring, Slotting, Face milling
