YG-1 E5021 Carbide Square Nose End Mill, TIALN Multilayer Finish, 30 Deg Helix, 4 Flutes, 2.5" Overall Length, 0.375" Cutting Diameter, 0.375" Shank Diameter

Key features

• 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

The YG-1 E5021TF TiAlN-coated carbide square nose end mill has four flutes, a center-cutting design, and a 30-degree helix angle for general-purpose machining on steel, chromium-nickel steel, and cast iron. Four flutes produce a better finish than fewer flutes. The tool’s square end creates sharp, unrounded cuts. The center-cutting design has cutting teeth at the end of the tool, so it can be fed into the workpiece like a drill bit. The 30-degree helix angle supports general-purpose applications. It balances lower angles’ strong cutting edge for difficult-to-machine materials with higher angles’ increased cutting action.The TiAlN coating resists heat better than the uncoated finish, TiN coating, and TiCN coating, increasing tool life and performance. It also offers increased hardness compared to TiN and may reduce the need for lubricants based on the application. The carbide substrate is harder than high-speed or cobalt steel, making it more wear resistant at high speeds and providing longer tool life. Cutting diameter tolerance is + 0.0000 to - 0.0012". The round shank accommodates a range of tool holders. End mills are designed to remove material and create multi-dimensional shap
