该产品集钻孔与攻丝于一体，结构独特，一件多用。已形成系列产品，本夹头只需移动紧圈，即可使钻孔、攻丝套筒快速调换。钻孔时，莫氏套筒能自动锁定；攻丝时，扭矩过载能平稳打滑，避免丝锥着段。不同直径丝锥，只要调节螺母松紧即可得到不同打滑扭矩方便迅速。适合车床、钻床、镗床上作业，大大地减轻劳动强度，节约辅助时间百分之八十以上。型号莫氏号钻孔范围攻丝范围钻孔套筒攻丝套筒J4320/2MT2φ1-23M5-M20D4MT1#MT2#M56-810121618-20J4320/3MT3J4320/4MT4J4330/3MT3φ1-31.5M6-M30D4MT1#MT2#MT3#M6-810121618-202427-30J4330/4MT4J4330/5MT5J4342/4MT4φ8-50M16-M42MT1#MT2#MT3#MT4#M1618-202427-303639-42J4342/5MT5J4342/6MT6J43100/5MT5φ31.5-76M45-M100MT4#MT5#M45-4852-5660-6468-7276-9095-100)
