short step drills
before threading
carbide
CARBIDE = hardness 1800 HV & 3500 HV, to machine steels over 1300 N/mm², treated steels up to 67 HRC, stainless steels, titanium alloys, hard bronzes, inconel, nimonic, waspaloy, hard cast irons and all other metals, thermoplastics, nylon, Pvc, laminated materials graphite, reinforced polymer with glass or carbon fibres, all ceramics, glass.

These step drills are designed for combining both boring and counterboring before threading operation. Their conception insures rigidity and longer tool life. The serie 8254-H is particularly suggested for NC - machine utilisation.
