The 4–20mm Twin Flute Straight Step Drill is designed for clean, accurate hole enlargement in thin materials. It drills and deburrs in one smooth operation, making it fast and efficient for metalworkers, electricians, fabricators and DIY users. Suitable for non-ferrous metals, sheet steel and plastics up to 3mm thick, it performs best when used with a non-hammer action portable drill.
