HSS Square Tool Bit Blanks

tool bit

High-speed steel (HSS) tool bits are cutting tools made from an alloy that can withstand high temperatures and retain hardness, used in applications like drilling, milling, and turning on lathes. They are a cost-effective and durable choice for general machining across various materials including metals, wood, and plastics. Common uses include drill bits, lathe tool bits, milling cutters, taps, and reamers. ALL MADE IN USA - NO CHINA

Key Characteristics

  • Material Composition: HSS is an alloy tool steel containing elements like tungsten, molybdenum, chromium, and vanadium, and sometimes cobalt (in M42 grades) to enhance performance.
  • Heat Resistance: HSS bits retain their hardness and cutting edge at high temperatures (up to around 600°C), which allows for higher cutting speeds than traditional carbon steel tools.
  • Durability and Toughness: They offer a good balance of toughness, wear resistance, and high impact strength, making them durable and less prone to breakage compared to carbide.
  • Resharpening: A significant advantage is that HSS tools can be resharpened at a low cost, extending their useful life.
