The Solid Round Dies-D, realize consistent thread cutting by adopting HSS material. ⑤ ①The 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 ⑥ direction. ②The rear face becomes Above is the picture of RD-DA（refer to ⑩-53） ⑦ the base for cutting. The Solid Round Dies-D Rear face（Basis for cutting） Adjustable Dies Solid Round Dies-D rear face has a recess so that the die can fit tightly in the die holder when installing.⑧※Solid Round Dies-D cannot be used Shallow counterbore Stable basis face 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 ⑨ outside diameter has been greatly improved. ④D has succeeded in solving difficult problems related to adjustable dies and achieved the high precision cutting of external threads. ⑩ Cutting condition Adjustable Dies Solid Round Dies-D Die size［DⅡ M６×１（20）］ Tears and stripes on thread flanks Work material Free cutting steel Cutting speed ２．６m/min Feed Free ⑪ Machine Engine lathe Cutting Fluid Non-water soluble cutting oil ※External threads cut by Solid Round Dies-D JIS 　have less tears and stripes on thread flank face. ⑩-1
