Key Features

  • Center-cutting design allows the end mill to plunge into material like a drill bit for applications such as slotting, drilling, and pocketing, as well as general-purpose machining
  • Suitable for machining on hardened and high-alloy steel, chromium-nickel steel, steel casting, and malleable cast iron
  • 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 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

Product Description

The YG-1 E5020TF TiAlN-coated carbide square nose end mill has two flutes, a center-cutting design, and a 30-degree helix angle for a range of plunge-milling and general-purpose applications on hardened and high-alloy steel, chromium-nickel steel, steel casting, and malleable cast iron. 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 such as slotting, drilling, and pocketing, as well as general-purpose machining. 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 tool’s square end creates sharp, unrounded cuts. 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 and 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.
