17000069 Carbide Corner Radius End Mill, Long Length, Long Reach, Inch, AlTiN Finish, Roughing and Finishing Cut, 35 Degree Helix, 3 Flutes, 4' Overall Length, 0.500' Cutting Diameter, 0.500' Shank Diameter, 0.03' Corner Radius

Niagara Cutter uses an "extra fine" grain cemented carbide raw material that is a true sub-micron grain tungsten carbide alloy. Niagara Cutter's carbide material is classified within the C1 to C4 range, and has an excellent combination of strength and toughness. Using raw materials with unique properties and high purity ensure Niagara Cutter's consistent high quality. Specifically designed for machining Aluminum, Stainless Steel, Titanium and Exotic Alloy Materials. Niagara Cutter is a leader in cutting tool technology and is proud to have their products made in the USA.

• Corner radius end mills have cutting edges with rounded corners to reduce chipping and provide longer tool life
• Extended-reach neck style provides access to recessed areas of the workpiece
• 35-degree helix angle provides increased cutting action and chip evacuation compared to lower helix angles for machining stainless steel and titanium
• Three flutes provide better chip-carrying capacity than four flutes and a finer finish than two, reducing the need for a second finishing cut in some applications
• Titanium aluminum nitride (TiAlN) coating lubricates the end mill for high-temperature stability and abrasion resistance at high cutting speeds, offering better heat resistance than TiN and TiCN coatings
