They are tapered at the point to facilitate entering of holes which are out of alignment.. Construction or Car Reamers are especially adapted for heavy duty reaming as encountered in the fabrication of structural steel assemblies.
This increases hardness (Rc 75-80) without increasing brittleness, which is measurably harder than high speed steel. Body and clearance are gold and black surface treated for maximum lubricity..
The Nitro Heavy-Duty Construction Reamers have a Ferritic Nitro Carburizing surface treatment, which gives a hard, protective layer to the reamer. Body and clearance are gold and black surface treated for maximum lubricity.
