Magnum 1/4 Inch 4 Flute Cobalt End Mill with 3/8 Inch Shank Precision Mill (EM14C)

Prolonging tool life in abrasive alloys requires a substrate that can handle intense heat without losing its edge. This 4-flute cobalt end mill features a 3/8" shank for increased rigidity and compatibility with common tool holders. It is engineered for horizontal profiling and fine finishing passes in stainless steel and high-tensile material applications.

Features

• M42 Cobalt Alloy - Superior red-hardness for high-heat industrial milling tasks.
• 3/8" (9.53 mm) Shank - Provides increased rigidity and fits standard 3/8" tool holders.
• 4-Flute Center Cut - Ideal for peripheral profiling and achieving high-quality surface finishes.

Frequently Asked Questions

Q: Why use a 3/8" shank on a 1/4" mill? A: The larger shank offers significantly more rigidity, reducing vibration and allowing for more aggressive cuts without tool deflection.

Q: Is this suitable for dry machining? A: Cobalt can handle more heat than HSS, but using coolant or air blast will greatly extend tool life in abrasive materials.
