An “HSS END MILL CUTTER 4 FLT” is a high-speed steel rotary cutting tool with four flutes, designed for machining operations like slotting, side milling, and creating shapes on a milling machine. The four flutes provide good chip evacuation, wear resistance, and are generally suitable for harder materials like steel, cast iron, and alloy steel.
Key features
- HSS (High-Speed Steel): The material is hardened for durability and wear resistance, with surface hardness often up to HRC62-66.
- 4 Flutes: The four-flute design is ideal for harder materials like steel and cast iron, providing better chip evacuation and durability compared to 2-flute designs.
- End Mill Cutter: This is a rotary tool used for machining surfaces, grooves, and steps in a workpiece. Unlike a drill bit, it can cut sideways as well as up and down.
- Applications:
- Machining planes, steps, and grooves.
- Rough and finish milling of materials like carbon steel, cast iron, alloy steel, and stainless steel.
- Also used for aluminum, copper, and plastics, depending on the specific cutter and its coating.
- Shank: The shank is the part that is held in the milling machine’s chuck. Common types include straight or Weldon shanks.
- Cutting Action: The cutter rotates while the workpiece is fed against it, removing material to create the desired shape.
