YG-1 E5021 Carbide Square Nose End Mill, TIALN Multilayer Finish, 30 Deg Helix, 4 Flutes, 2.5\ Overall Length, 0.25\ Cutting Diameter, 0.25\ Shank Diameter
- Suitable for general-purpose machining on steel, chromium-nickel steel, and cast iron.
- Four flutes produce a better finish than fewer flutes.
- 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 uncoated finish, TiN coating, and TiCN coating.
- Carbide can run at higher speeds than high-speed or cobalt steel, resisting wear and high cutting temperatures.
- Square nose end mills (also called square end) create sharp, unrounded cuts.
