Cobra Carbide 29418 Micro Grain Solid Carbide Regular Length Hi-Performance End Mill, TiAlN Coated, 6 Flute, 45 Degrees Helix, Square End, 1' Cutting Length, 1/2' Cutting Diameter, 3' Length (Pack of 1): Square Nose End Mills: Industrial & Scientific. Cobra Carbide 29418 Micro Grain Solid Carbide Regular Length Hi-Performance End Mill, TiAlN Coated, 6 Flute, 45 Degrees Helix, Square End, 1" Cutting Length, 1/2" Cutting Diameter, 3" Length (Pack of 1): Square Nose End Mills: Industrial & Scientific. 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 。 Titanium aluminum nitride coatings become self-lubricating when used at very high speeds, making them ideal for cutting without coolant ("dry machining") 。 Round shanks allow use with a wide variety of toolholding systems 。 Multi flute design allows for less chatter and vibration free operations 。 Lighter chip load per tooth increases tool life and providing better finish 。 Cobra Carbide hi-performance end mill is manufactured from premium sub micro grain carbide. Multi-flute design allows for less chatter and vibration free operations. Lighter chip load per tooth increases tool life and providing better finish. TiAlN and CG coated for increased tool life. Excellent accuracy. 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. Titanium aluminum nitride coatings become self-lubricating when used at very high speeds, making them ideal for cutting without coolant ("dry machining"). Round shanks allow use with a wide variety of toolholding systems. Work material: good for aluminum alloy, carbon steel, cast iron; excellent for alloy steel, hardened steel, nickel/inconel alloy, stainless steel and titanium. 。 。 。
