55mm Powder Steel Durablue Coated Annular Cutters, Weldon Shank
Annular cutter powder steel + DURABLUE coated.
Only coated powder steel annular cutters offer a similar level of performance as carbide tipped annular cutters.
Under hard field conditions only in the rarest cases optimum speed and cooling can be considered. The Karnasch DURABLUE coating makes the annular cutter decisively more resistant. This results finally to an extraordinary increase of lifetime.
BLUE-LINE PRO annular cutters are the right choice for most difficult materials (As standard coated annular cutters do we recommend our BLUE-LINE range, see 201312; 201313; 201285; 201280)
Made of ASP powder steel + DURABLUE coating.
Our first-class annular cutter are equipped with the unique and patented DURABLUE coating.
Extreme surface hardness and sleekness yield extreme lifetimes even under non-optimum conditions like overhead drilling with a little or without coolant.
Only few manufacturers are capable of producing step-hardened annular cutter.
For Karnasch this is standard. Only this makes us produce extremely hard tooth tips [68 HRC] and yet a flexible annular cutter.
Completely made FULLY GROUND. This refining rises the cutting ability with reducing friction at the same time. For an exceeded lifetime.
For drilling of all kind of steel up to 1400 N and difficult materials like railway tracks, stainless steels, exotic alloys. Applicable wherever a high wear resistance and lifetime are required. Ideal for drilling railways, for all rail types up to 1100 N [UIC 60]. More than 100 holes in UIC 60 rails possible.
