About
【Six Sizes】This spiral drill bit set includes six commonly used sizes — 3mm, 4mm, 5mm, 6mm, 6.5mm, and 8mm — so you always have the right twist drill bit for the task. Whether you need a single twist drill bit for a quick repair or a matched set of twist drill bits for a full project.
【Titanium Coated HSS】Crafted from premium high-speed steel with a titanium finish, this twist drill bit set delivers increased surface hardness and wear resistance for sustained cutting performance.
【135° Split Point】The innovative serrated drill bits feature side-cutting serrations along the flute, allowing horizontal cutting and slot expansion after the initial breakthrough. Each serrated side cut drill bit handles notching, grooving, and enlarging holes with ease.
【Multi-Material Drilling Across】The sharp cutting edges and spiral flute design evacuate chips efficiently, producing clean, burr-free holes. From woodworking and cabinetry to light metal fabrication and plastic fabrication, these bits handle a broad range of materials without requiring frequent bit changes.
【Universal Shank Compatibility】Each bit features a standard round shank compatible with most cordless drills, corded drills, and bench drill presses — no special adapters needed. Keep one set in your toolbox and another in the workshop for ready access whenever a job calls for precision drilling.
