- Standards
- Item Features
OSHA 29 CFR Part 1926.759
- 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
