A drill bit is a cutting tool used in a drill to remove material to create holes, almost always of circular cross-section. Drill bits come in many sizes and shapes and can create different kinds of holes in many different materials. In order to create holes drill bits are usually attached to a drill, which powers them to cut through the workpiece, typically by rotation. The drill will grasp the upper end of a bit called the shank in the chuck.
One step drill bit replaces 3-5 conventional bits, saving tool-change time-ideal for multi-diameter needs, confined spaces (e.g., inside enclosures), and precision hole finishing.
1.Multi-diameter in one operation: Drills holes from 3-12mm with a single bit, eliminating tool changes.
2.Precision hole finishing: Stepped design ensures smooth walls with minimal burrs (±0.1mm tolerance).
3.Efficient chip removal: Optimized flutes prevent clogging for continuous drilling.
4.Extended durability: HSS or cobalt alloy offers 3x longer lifespan vs standard bits.
5.Material versatility: Works on metal (steel/aluminum/copper), plastic, wood, etc.
6.Nano-coating: TiN/TiAlN coating reduces heat buildup (resists 800ºC).
7.Anti-vibration shank: Hex shank fits power/hand tools securely.
