  • Item Features
  • Manufactured from a premium grade of m-7N molybdenum HSS
  • The Nitro® heavy duty construction reamers have a ferritic nitro carburizing surface treatment, which gives a hard, protective layer to the reamer
  • This increases hardness (Rc 75 to 80) without increasing brittleness, which is measurably harder than HSS
  • Body and clearance are gold and black surface treated for maximum lubricity
