12-Piece Titanium HSS Twist Drill Bit Set, Serrated Side Cutting

Key features

• Drill and Cut Sideways to Enlarge Holes — These serrated side cutting drill bits function as a drill saw bit, allowing controlled side cutting after drilling to enlarge existing holes, shape openings, and create simple slots in wood and plastic. Designed for DIY woodworking, repairs, and creative modifications where standard twist drill bits cannot easily modify the shape or size of an opening.
• TITANIUM COATED HSS FOR CLEAN DRILLING & LONG-LASTING SHARPNESS: Made from high-speed steel with titanium coating for improved wear resistance and smoother drilling performance. Precision ground tips help reduce walking at startup, while spiral flutes remove chips efficiently for cleaner holes with less heat buildup. These titanium coated drill bits work well on: soft wood, plywood, MDF, PVC, plastic and light drilling on thin sheet metal.
• Versatile for Woodworking, DIY Projects, and Home Repairs — Whether you are building furniture, repairing PVC pipes, or working on craft projects, these multi-material drill bits handle everyday drilling and hole modification tasks. The 12-piece set covers 5 practical sizes: 2 each of 1/8 inch and 5/16 inch, 1 of 5/32 inch, 3 of 3/16 inch, and 4 of 1/4 inch, so you always have the right size from small drill bits to larger ones for common DIY needs.
• Get Optimal Results with the Right Side-Cutting Method — For optimal side-cutting results, drill a starter hole first, then use larger sizes such as 1/4 inch and 5/16 inch. Maintain sufficient drill speed; if your drill stalls when moving sideways, the RPM is too low. Apply light, controlled pressure. Do not use thin bits (1/8 to 3/16 inch) for side cutting as they may snap under lateral force. Optimized for soft wood, plywood, and PVC; not recommended for drywall, hardwood, or metal.
• Universal Round Shank with Organized Storage Case — The standard round shank fits most cordless drills, electric drills, and drill presses. Clearly marked size labels make it easy to select the right bit quickly, while the storage case keeps each twist drill bit organized and protected. A technique reference card with speed and material guidelines is included. Package contains 12 titanium coated HSS drill bits in 5 sizes and one storage case.
