产品规格	The hand taps most commonly employed today are used in conjunction with a machine, e.g. a tapping machine, rather than by hand. Thus, it is more common to employ a tap with a cutter shape most suitable for the conditions of use than using in sequence, three taps, i.e. the taper tap, plug tap and bottoming tap. Two kinds of materials of Carbon Steel and High Speed Steel are available. When ordering, please specify which one.
中文汉化	631078 指套式米制粗螺纹M20，P2.50毫米，高速钢这种手攻丝通常与机器，如攻丝机一起使用，而不是手动。因此，更常见的是使用适合使用条件的切削形状的攻丝器，而不是依次使用锥攻、堵头攻和底孔攻。有两种材料可供选择：碳钢和高速钢。下订单时请注明是哪种。
