Cobra Carbide hi-performance end mill has excellent roughing with reduced heat in the cut for hard material. Fine profile, 4 flute, right hand helix. Small corner radius/chamfer for strength. Form relieved on high strength carbide for excellent profile milling. For profiling, plunging, and ramping roughing operations in all types of hard material. Solid carbide tools offer long tool life and faster cutting speeds than other substrates, but are more brittle and must be used with rigid toolholding systems. Uncoated tools feature just the base substrate without any additional treatment or coatings and are suitable for a wide range of applications. Round shanks allow use with a wide variety of toolholding systems. Work material: titanium; good for aluminum alloy, nickel/inconel alloy, cast iron; excellent for carbon steel, alloy steel, hardened steel and stainless steel.
