The Dormer Trochoidal End Mill is a short series, high-performance cutting tool designed for versatile machining applications. With its five flutes, solid carbide composition, and AlCrN coating, this end mill is ideal for shoulder milling, ramping, helical milling, and trochoidal milling in steel, cast steel, stainless steel, cast iron, and high-temperature alloys. The unequal helix and 10 rake angle contribute to its efficiency in various milling processes. The AlCrN coating provides thermal stability, minimizes friction, ensures excellent wear resistance, and extends overall durability. This tool is a reliable choice for achieving precise and efficient results in a range of machining tasks.Features and Benefits Micrograin Carbide providing extreme hardness and wear resistance providing increased tool life when machining difficult materials
