Description
- Premium M35 Cobalt Construction – Heat-treated high-speed steel with 89HRC hardness outperforms standard bits, metal drill bits for hard steel offering exceptional wear resistance for drilling hardened steel, stainless steel, and tough alloys without dulling.
- 11 Precision Steps (3-13mm) -Steel drill bits for hard steel single bit replaces multiple drill sizes with graduated steps for clean holes in sheet metal, pipes, or panels – no more switching between bits for different hole sizes.
- Advanced AlTiN Coating & Spiral Flutes – Cobalt drill bits titanium-aluminum nitride coating reduces friction while spiral grooves efficiently remove chips for cooler, faster drilling in metals up to 1/4" thick.
- Universal 1/4" Hex Shank – Step drill bit for metal fits all standard drill chucks including impact drivers, drill presses, and hand drills – ideal for automotive, HVAC, electrical, and metal fabrication projects.
- Multi-Material Versatility – Works on steel, aluminum, plastics, and wood (not for masonry) – cone drill bit includes usage tips: use cutting oil for metals, start slow for cleaner holes, ideal for DIY and pro applications.
