25mm 8 Flute Solid Carbide End Mill for Engine Components Specialized Milling Cutter for Steel Cast Iron HRC55 Hardness TiAlN Coated CNC Machining

25mm 8 Flute Solid Carbide End Mill for Engine Components Specialized Milling Cutter for Steel Cast Iron HRC55 Hardness TiAlN Coated CNC Machining

Introduction:

Our 25mm 8-flute solid carbide end mill is specifically engineered for high-performance machining of engine components in steel and cast iron. Designed for automotive and industrial engine manufacturing, this specialized milling cutter features premium micro-grain tungsten carbide (0.5μm) with TiAlN coating to withstand the demanding conditions of engine block and cylinder head machining. The optimized 8-flute design delivers exceptional metal removal rates while maintaining precision in continuous and interrupted cutting operations.

Features:

• • • Engine-specific carbide formulation (YG10X grade)

• • • 8-flute high-density design for maximum productivity

• • • TiAlN coating (3-4μm) for extreme heat resistance

• • • Precision ground cutting edges (±0.01mm tolerance)

• • • 30° helix angle with variable pitch for vibration control

• • • Special edge preparation for interrupted cuts

• • • Heavy-duty core design (12% thicker web)

• • • Coolant-through option available

Advantages:

✓ 60% higher feed rates than standard end mills

✓ 5× longer tool life in cast iron applications

✓ Reduced harmonic vibration through optimized geometry

✓ Maintains dimensional accuracy in prolonged production runs

✓ Engineered for both roughing and semi-finishing

Typical Applications:

• • • Engine block decking and milling
