YG-1 - 55901 E5065 Carbide Square Nose End Mill, Extra Long Reach, Uncoated (Bright) Finish, 30 Deg Helix, 4 Flutes, 6" Overall Length, 0.25" Cutting Diameter, 0.25" Shank Diameter

Key features

• Suitable for general-purpose machining on hardened and high-alloy steel, steel casting, malleable cast iron, chromium-nickel steel, brass, copper, aluminum with a high percentage of silicon, and abrasive plastic
• Extra-long-length end mills have longer cutting edges and can make deeper cuts than long-length end mills
• Four flutes produce a better finish than fewer flutes
• Carbide can run at higher speeds than high-speed or cobalt steel, resisting wear and high cutting temperatures
• Uncoated (bright) tools have no additional surface treatment or coating for use on a broad range of materials

The YG-1 E5065 uncoated carbide extra-long-length square nose end mill has four flutes, a center-cutting design, and a 30-degree helix angle for general-purpose machining on hardened and high-alloy steel, chromium-nickel steel, steel casting, malleable cast iron, brass, copper, aluminum with a high percentage of silicon, and abrasive plastic. Extra-long-length end mills have longer cutting edges than long-length end mills for applications with a high depth of cut. (Feed should be reduced by around 50%.) 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.Carbide is harder than high-speed or cobalt steel, making it more wear resistant at high speeds and providing longer tool life. With no coating or surface treatment, this uncoated tool can be used on a broad range of materials. Cutting diameter tolerance is + 0.0000 to
