6 Pack HSS Step Drill Bits, 3-8mm Hex Shank Serrated Side Cutting Bit Set

Product features

1. Titanium Coated HSS Steel: These twist drill bits are crafted from high-speed steel and finished with a titanium coating that reduces friction and heat buildup, with a hardened surface that resists dulling and corrosion for cleaner holes
2. Serrated Side Cutting Design: Unlike standard straight-flute bits, each bit features aggressive side teeth that cut horizontally as you guide the tool, perfect for widening existing holes, creating elongated slots, or shaping irregular openings
3. Hex Shank Compatibility: The 6.35mm hex shank fits securely into standard quick-release drill chucks and impact drivers, preventing annoying slippage and letting you swap between bit sizes in seconds without readjusting torque settings
4. Versatile 3-8mm Assortment: This 6-piece set covers diameters from 3mm to 8mm, meeting diverse needs from fine woodworking to plastic fabrication and sheet metal installation, with a storage case for quick selection
5. Ideal for Woodworking: Whether you're installing cabinet hardware, routing plastic enclosures, or enlarging structural holes for conduit and pipe, these side cutting bits deliver smooth precise results for professionals and weekend crafters alike
