Key Features

  • Suitable for high-performance machining on stainless steel and high-temperature alloys
  • 40-degree helix angle provides increased cutting action and chip evacuation compared to end mills with lower helix angles
  • Stub length increases the strength of the tool, making it less likely to break in the workpiece
  • Aluminum titanium nitride (AlTiN) coating lubricates the end mill for high-temperature stability and abrasion resistance at high cutting speeds, offering better heat resistance than TiN, TiAlN, and TiCN coatings
  • Carbide can run at higher speeds than high-speed or cobalt steel, resisting wear and high cutting temperatures

Product Description

The Melin Tool AMGS40-series AlTiN-coated carbide stub-length square nose end mill has a 40-degree helix angle, two flutes, and a center-cutting design for high-performance machining on stainless steel and high-temperature alloys. The 40-degree helix angle offers increased cutting action and chip evacuation compared to end mills with lower helix angles, as it moves excess material quickly up the spiral and away from the workpiece. 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 AlTiN coating resists heat better than TiN, TiAlN, 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. Carbide 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 + 0.000 to - 0.002". 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.

Melin Tool manufactures cutting tools such as end mills, countersinks, drills, and thread mills. The company, founded in 1940, is headquartered in Cleveland, OH.
