The Solid Round Dies-D, realize consistent thread cutting by adopting HSS material. Cemented Carbide Taps ⑤ ①T he side with markings Solid Round Dies-D Front face on its bevel, is the front Markings on its bevel portion face.This makes it easy to determine the cutting Roll Taps direction. ⑥ ②The rear face becomes Above is the picture of RD-DA（refer to ⑩-53） Special Thread Taps Simple Inspection Tools the base for cutting. The Solid Round Dies-D Rear face ⑦ Adjustable Dies Solid Round Dies-D （Basis for cutting） rear face has a recess so that the die can fit tightly in the die holder when installing. Pipe Taps Stable basis face ⑧ ※Solid Round Dies-D cannot be used Shallow counterbore from Rear face. Adjustable Dies Solid Round Dies-D ③D is solid type and does not need the adjusting screw. Compared with adjustable type, accuracy of D's Thread Mills Premium Thread Mills outside diameter has been greatly improved. ⑨ ④D has succeeded in solving difficult problems related to adjustable dies and achieved the high precision cutting of external threads.
