For multiple applications, sizes and hole enlargement in maintenance repair operations including electrical, plumbing / HVAC, metal working / fabrication, telephone and antenna cabling and electrical wiring redirection.

Rapid Strike tip improves centering to allow fast drilling without the need to punch, and allows accurate start on contact without walking. Optimised 2-flute ground sharpened edge geometry provides fast and smooth cutting. Secure 3-flat grip prevents step drill from slipping in the chuck and ensures maximum transmission of torque.
