TUNGSTEN CARBIDE TIPPED (T.C.T) TEETH | 优质硬质合金刀头: Features ultra-hard Tungsten Carbide teeth that maintain their sharp cutting edge far longer than standard HSS hole saws. This industrial-grade material is specifically engineered for high-speed cutting through tough metals.
采用超硬硬质合金（T.C.T）刀头，具备卓越的硬度与保刃性，使用寿命远超普通高速钢开孔器。该工业级材质专为坚硬金属的高速切削而设计。

STAINLESS STEEL & METAL SPECIALIST | 不锈钢与厚金属切削专家: Optimized for drilling through challenging materials including stainless steel (up to 2mm), mild steel, iron plates, and aluminum. The heavy-duty construction ensures smooth penetration without deforming the bit.
专门针对高难度材质进行优化，可轻松钻透不锈钢（最高 2mm）、软钢、铁板及铝材。重型结构确保在切削过程中保持稳固，不会产生变形。

INTEGRATED CENTER PILOT DRILL | 内置精准中心定位钻: Equipped with a replaceable HSS center pilot drill that ensures accurate hole positioning. This prevents the hole saw from "walking" or skating on smooth metal surfaces, ensuring a perfect hole every time.
配备可更换的高速钢中心定位钻头，确保开孔位置精准无误。有效防止开孔器在平滑的金属表面产生打滑或偏移，确保每一次开孔都圆润完美。

EJECTION SPRING TECHNOLOGY | 强力弹簧自动排屑系统: Features a built-in heavy-duty ejection spring that automatically pushes out the metal slug once the cut is finished. This prevents clogging and significantly speeds up repetitive industrial drilling tasks.
内置重型强力弹簧设计，在完成切削后自动弹出金属芯料。有效防止碎屑堵塞，并能显著提升重复性工业钻孔作业的整体效率。

HEX SHANK FOR HIGH TORQUE | 三面六角防滑安全柄: Designed with a reinforced hexagonal shank that fits securely into standard three-jaw chucks and magnetic drills. This prevents slippage under high torque, providing maximum safety and stable power transfer.
采用强化三面六角柄设计，可牢固安装在标准三爪夹头及磁座钻上。有效防止在高扭矩作业下产生打滑，提供极高的操作安全性与稳定的动力传输。
