YG-1 E1070 High Speed Steel (HSS) Square Nose End Mill, Weldon Shank, Uncoated (Bright) Finish, 42 Deg Helix, 2 Flutes, 3.75" Overall Length, 0.625" Cutting Diameter, 0.625" Shank Diameter

Key features

• Suitable for machining on aluminum and other nonferrous materials
• 42-degree helix provides increased cutting action compared to end mills with lower helix angles
• Two flutes offer better chip-carrying capacity than end mills with more flutes, enhancing the tool’s ability to remove material
• Center-cutting design allows the end mill to plunge into material like a drill bit while also performing conventional surface milling
• High-speed steel for general-purpose

The YG-1 E1070 uncoated high-speed steel square nose end mill has a 42-degree helix angle, two flutes, and a center-cutting design for general-purpose machining on aluminum and other nonferrous materials. The 42-degree helix angle offers increased cutting action compared to end mills with lower helix angles, as it moves excess material quickly up the spiral and away from the workpiece. The two flutes have better chip-carrying capacity than end mills with more flutes while offering additional support when the tool goes deep into the material in applications with a high depth of cut. 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 tool’s square end creates sharp, unrounded cuts. High-speed steel (HSS) is a common general-purpose steel for cutting tools. This tool has no coating or surface treatment. Cutting diameter tolerance is + 0.0010 to - 0.0000" for end mills with a different shank and cutting diameter and + 0.0015 to - 0.0000" for end mills with the same shank and cutting diameter. The tool has a Weldon shank. End mills are designed to remove material and create multi-dimensional shapes and profiles.
