Suitable for general-purpose machining on hardened and high-alloy steel, cast iron, and chromium-nickel steel
Stub length increases the strength of the tool, making it less likely to break in the workpiece
Two flutes offer better chip-carrying capacity than end mills with more flutes, enhancing the tool''s ability to remove material
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 TiN and TiCN coatings
Carbide can run at higher speeds than high-speed or cobalt steel, resisting wear and high cutting temperatures

Product Description

The YG-1 E5244 TiAlN-coated carbide stub-length square nose end mill has two flutes, a center-cutting design, and a 30-degree helix angle for general-purpose machining on hardened and high-alloy steel, cast iron, and chromium-nickel steel. The stub length increases tool strength and makes it less likely to break in the material being machined. It is best used when depth of cut is shallow. The two flutes have better chip-carrying capacity than end mills with more flutes while offering additional support when the tool goes into the material. 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 TiN and TiCN coatings, 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 shapes and profiles. They have cutting edges along the outside diameter and flutes that remove chips from the cutting area and allow cooling fluids to enter. If heat is not reduced effectively, the tool’s cutting edges will dull and additional material buildup can occur. The number of flutes can range from two to eight. Two-flute designs offer the most efficient chip removal, but more flutes provide a smoother finish. The shank is the end of the tool held in place by a tool holder or machine. Center-cutting end mills can create three-dimensional shapes and profiles, and make plunge cuts similar to a drill bit. Non-center-cutting end mills are for applications such as peripheral milling and finishing, but cannot make plunge cuts.
YG-1 manufactures drills, taps, end mills, and rotary tooling. The company, founded in 1981, is headquartered in South Korea and has a U.S. office in Vernon Hills, IL.
