钻尖换、钻杆留：SMD 皇冠钻做螺纹底孔和深孔，精度稳住了，刀具账也好算了
SMD 皇冠钻是换钻尖的路子：SMDT2000 钻尖配 SMD-3D-077-C25 钻杆，靠放射状嵌合的结合面定位。装上去咬合紧，钻起来不容易晃，孔口和孔壁的稳定性有保障。
孔径精度能到 8-9 级，加工螺纹底孔正合适。钻杆本身做得扎实，不同工况的孔都能应付。直径覆盖 12-30mm，倍径分 1.5 / 3 / 5 / 8 / 12 五个系列，浅孔深孔都有对应型号。
Each part is engineered and QC'd against the exacting standards your equipment demands.
SMDT2000 磨损了只换钻尖，SMD-3D-077-C25 钻杆继续用，长期算下来刀具成本降得明显
合，钻尖落位后咬得紧，加工中不容易松动，定位稳定性比普通装夹方式更让人放心
级，攻丝前打底孔不用反复修，螺纹底孔这道工序能一次做稳
