- Efficient Multi-Size, All-in-One Solution: Equipped with 5 step drill bits covering a wide range of sizes (1/4"-3/4", 1/8"-1/2", 3/16"-7/8", 3/16"-1/2", 3/16"-1-3/8"), eliminating the need for frequent bit changes and effortlessly handling diverse drilling requirements. A bonus chamfering tool is included for instant burr removal after drilling, saving time and effort.
- 4-Flute Double Speed, Long-Lasting Durability: Features a 4-flute design that doubles drilling speed and efficiency. Made of high-performance High-Speed Steel with a titanium coating, it delivers exceptional wear resistance and significantly extends service life.
- Precision and Stability, Risk-Free Operation: The tapered design combined with a 1/4-inch hex shank and 9mm round shank, ensures precise, stable drilling with minimal vibration. Its industrial-grade one-piece construction and seamless, non-welded shank design enhance rigidity, enabling it to withstand sudden impacts—perfect for high-intensity tasks.
- Step-Up Versatility, Single-Tool Adaptability: The stepped structure integrates both unibit and stepdown bit functions, allowing multiple hole sizes to be drilled without switching bits. The spiral flute design adapts to materials of varying thicknesses, ensuring smooth, jam-free drilling.
- Smooth Finish, Broad Material Compatibility: Achieves burr-free results and reduces heat buildup, significantly improving surface finish. Compatible with stainless steel, aluminum, copper, PVC, and more (not suitable for brittle materials like glass, tile, or stone). Its short-tube one-piece structure ensures robustness and durability, making it ideal for professionals and DIY users alike.
