PREMIUM M2 HIGH-SPEED STEEL | 工业级 M2 高性能高速钢: Manufactured from high-grade M2 High-Speed Steel (HSS), offering superior industrial-grade toughness and heat resistance. This premium material ensures the bits maintain their edge much longer than standard HSS when drilling through 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 材质在钻削高硬度金属时能显著延长刃口锋利度，确保作业高效。

TITANIUM NITRIDE (TiN) COATING | 氮化钛金超硬涂层: Treated with a specialized gold Titanium coating to reduce friction and surface heat. This protective layer extends the tool’s lifespan by up to 5 times during continuous high-speed industrial drilling.
表面经过专业级氮化钛（TiN）涂层处理，有效降低切削摩擦与表面热量。该涂层在连续高速工业钻孔作业中，可将钻头使用寿命提升高达 5 倍。

135° SPLIT POINT SELF-CENTERING | 135° 十字定位自对中钻尖: Features a 135-degree split point design that starts cutting immediately upon contact. This prevents the bit from "walking" or skating on hard surfaces, ensuring precise hole placement without a center punch.
配备 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金属表面产生打滑或偏移，无需预先打冲点即可实现精准定位。

PRECISION FULLY GROUND FLUTES | 全磨制精密螺旋排屑槽: Engineered with fully ground spiral flutes that facilitate rapid chip extraction and smooth boring. This design prevents clogging and overheating, even when drilling through thick steel plates.
采用全磨制精密螺旋槽设计，确保排屑迅速且钻孔顺滑。即便在钻削厚重的钢板时，也能有效防止碎屑堵塞与钻头过热，保持切削连贯性。

COMPREHENSIVE 25-PIECE RANGE | 25件套全规格覆盖: This professional set provides a wide variety of sizes for every technical requirement, suitable for drilling alloy steel, carbon steel, cast iron, aluminum, brass, and industrial plastics.
全套包含 25 种核心规格，满足各类专业工程需求。广泛适用于合金钢、碳钢、铸铁、铝材、黄铜及工业塑料等多种材质的钻孔作业。
