PREMIUM M2 HIGH-SPEED STEEL | 工业级 M2 高性能高速钢: Manufactured from premium M2 High-Speed Steel (HSS), offering superior industrial-grade toughness and heat resistance compared to standard HSS bits. This ensures the bits maintain a sharp cutting edge even under high-temperature drilling in dense metals.
采用工业级 M2 高性能高速钢精制而成，具备卓越的韧性与耐热性能。相比普通高速钢，M2 材质在高温切削下仍能保持锋利刃口，确保在高硬度金属钻孔作业中依然高效稳定。

TITANIUM NITRIDE (TiN) COATING | 氮化钛金超硬涂层: Treated with a high-performance gold Titanium coating that significantly reduces friction and surface heat. This protective layer extends the tool’s lifespan by up to 3 to 5 times during continuous high-speed industrial drilling.
表面经过高性能氮化钛（TiN）金黄色涂层处理，有效降低切削摩擦与表面热量。在连续高速工业钻孔作业中，该涂层可将钻头使用寿命显著提升 3 至 5 倍。

135° SPLIT POINT SELF-CENTERING | 135° 十字定位自对中钻尖: Features a professional 135-degree split point design that starts cutting immediately upon contact. This prevents the bit from "walking" or skating on hard, polished surfaces, ensuring precise hole placement without a center punch.
配备专业的 135° 十字分割钻尖设计，接触瞬间即可切入。有效防止钻头在坚硬或抛光金属表面产生打滑偏移，无需预先打冲点即可实现即时精准的中心定位。

PRECISION FULLY GROUND FLUTES | 全磨制精密螺旋排屑槽: Engineered with fully ground spiral flutes designed for rapid chip extraction and smooth boring. This high-efficiency design prevents clogging and overheating, even when drilling through thick steel plates.
采用精密全磨制螺旋槽设计，确保排屑迅速且钻孔顺滑。高效率的排屑结构即便在钻削厚重的钢板或金属件时，也能有效防止碎屑堵塞与钻头过热。

COMPREHENSIVE 19-PIECE METRIC RANGE | 19件套公制全规格覆盖: This professional set includes 19 essential metric sizes from 1.0mm to 10.0mm (in 0.5mm increments), making it ideal for drilling alloy steel, stainless steel, cast iron, aluminum, and heavy-duty industrial plastics.
全套涵盖从 1.0mm 至 10.0mm（以 0.5mm 递增）的 19 种核心公制规格。广泛适用于合金钢、不锈钢、铸铁、铝材、黄铜及高硬度工业塑料的钻孔作业。
