Burrs can be generated and the precision of the shank can be impaired by placing the markings on the shank's diameter. Roll Taps ⑥ To maintain the precision and the circularity of the finished shank diameter and maintain the high accuracy, the taps size and limits are now marked on the square portion of the tap. ●The AU+SL is applicable to a wide range of work materials. It utilizes a flute shape that can maximize the features of the wear and heat resistance by coating. Special Thread Taps Simple Inspection Tools The coating offers an adhesion resistance, and can handle a wide range of ⑦ work materials. It is also ideal for water soluble cutting fluids.
