HSS Rectangular Tool Bits

HSS (High-Speed Steel) rectangular tool bits are small, rectangular pieces of HSS steel used for cutting, shaping, and finishing in various machining operations. They are commonly used in lathes, milling machines, and other equipment. HSS tool bits offer superior strength, heat resistance, and durability, making them suitable for cutting a wide range of materials. 

Here's a more detailed breakdown:

  • Material: Made from high-speed steel, a type of tool steel known for its hardness and heat resistance. 
  • Shape: Rectangular, with varying sizes and bevel angles depending on the application. 
  • Applications: Used for cutting, turning, facing, grooving, and other machining operations. 
  • Advantages: High hardness, heat resistance, and durability, allowing for high-speed cutting and long tool life. 
  • Grades: Available in different grades of HSS, such as M2, M35, M42, and T42, each with specific characteristics for different applications. 
  • Heat Treatment: Often undergo a cryogenic heat treatment process to enhance wear resistance and ensure consistent performance.
