This Metric Step Drill Bit Range is designed for fast, accurate drilling and progressive hole enlargement in steel, stainless steel, timber and plastic. A specialized step-tip design eliminates the need for pre-drilling and helps reduce wandering, producing centered, round holes across a wide range of onsite installation and fabrication tasks.
Each drill features dual cutting edges for clean, burr-free holes and an AlTiN coating for extreme-temperature resistance and extended service life. The stepped cutting profile delivers up to three times faster cutting than a conventional step drill and helps prevent distortion when drilling sheet materials under 3.5mm thick. A 1/4" quick-change hex shank provides compatibility with suitable power drills and impact drivers.
