TITANIUM NITRIDE COATING | 氮化钛金超硬涂层: Treated with a high-performance Titanium coating to reduce friction and heat buildup, extending the service life of the cutting edges up to 6 times compared to standard bits.
表面经过高性能氮化钛涂层处理，有效降低切削摩擦与热量堆积，比普通钻头的使用寿命显著提升 6 倍以上。

HIGH-SPEED STEEL (HSS) CONSTRUCTION | 优质高速钢材质: Manufactured from premium-grade heat-treated HSS for exceptional hardness and toughness, allowing for efficient drilling through metal, wood, and plastic without losing sharpness.
采用优质热处理高速钢精制而成，具备极高的硬度与韧性，确保在金属、木材及塑料上高效钻孔且持久锋利。

DUAL-FLUTE DESIGN | 双螺旋/直槽切削设计: Features a precision-engineered dual-flute design that facilitates faster chip removal and smoother cutting, ensuring perfectly round and clean holes every time.
采用精密双槽（螺旋或直槽）设计，大幅提升排屑速度并使切削过程更加平稳，确保钻出的孔洞圆润、洁净。

MULTI-SIZE VERSATILITY | 多规格一钻多用: A single step drill bit replaces multiple standard bits, allowing you to drill or enlarge holes of various diameters incrementally without changing tools.
单支阶梯钻即可替代多支标准钻头，无需更换工具即可循序渐进地钻出或扩孔不同直径的孔洞，作业更灵活。

TRI-FLATTED/HEX SHANK | 三面/六角防滑柄部: Equipped with a specialized shank design that fits securely into three-jaw chucks and quick-change drivers, preventing slippage under high torque for maximum safety and power transfer.
配备专业防滑柄部设计，可牢固安装在三爪夹头或快换驱动器上，有效防止在高扭矩下产生打滑，确保操作安全及动力传输。
