Product features

1. Titanium Coated HSS Steel with Superior Wear Resistance: These twist drill bits are crafted from high-speed steel and finished with a titanium coating that reduces friction and heat buildup during drilling. The hardened surface resists dulling and corrosion, ensuring cleaner holes through multiple home improvement and workshop projects
2. Serrated Side Cutting Design for Enlarging and Grooving: 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 in wood, plastic, thin aluminum sheets, and soft steel
3. Hex Shank Compatibility with Chuck: The 6.35mm hex shank fits securely into standard quick-release drill chucks and impact drivers, preventing annoying slippage during operation. Swap between bit sizes in seconds without readjusting torque settings, ideal for multi-step drilling and carpentry tasks
4. Versatile 3-10mm Metric Assortment for Multi-Material Projects: This 8-piece set covers diameters from 3mm to 10mm, meeting diverse needs from fine woodworking to plastic fabrication and sheet metal installation. Organize the bits in the included storage case for quick selection during job site and bench work
5. Ideal for Woodworking Carpentry and DIY Home Renovation: 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. An essential addition to your power tool accessories for both professional tradesmen and weekend crafters
