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
