Product Description
- The Halls MC High-Speed Steel Step Drill Bit in the 20mm - 30mm size range is designed for larger diameter hole applications in sheet metal fabrication.
- This variant covers eleven consecutive sizes—20, 21, 22, 23, 24, 25, 26, 27, 28, 29, and 30mm—making it essential for HVAC work, larger cable entries, and ventilation installations.
- With a robust 13mm shank providing secure chuck grip and reduced flex during operation, this step drill handles the demands of larger hole cutting with confidence.
- The 1mm increments throughout the range allow for precise sizing of holes for specific fittings, flanges, and mounting hardware commonly found in commercial and industrial applications.
- Rated for sheet metal up to 4mm thick, this bit produces clean, burr-free holes that often require minimal finishing.
- When drilling metals, use a coolant to maintain cutting efficiency and prolong tool life, particularly important with these larger diameter cuts.
