YG-1 E1072 High Speed Steel (HSS) Square Nose End Mill, Extra Long Reach, Weldon Shank, Uncoated (Bright) Finish, 42 Deg Helix, 2 Flutes, 10.5" Overall Length, 0.5" Cutting Diameter, 1.25" 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
• Extra-long-length end mills have longer cutting edges and can make deeper cuts than long-length end mills
• Two flutes offer better chip-carrying capacity than end mills with more flutes, enhancing the tool’s ability to remove material
• High-speed steel for general-purpose cutting

The YG-1 E1072 uncoated high-speed steel extra-long-length 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. 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%.) 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 for applications. 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
