Note that ⑦ non-standard classes ofproducts are available as Shallow counterbore specified distribution items (made to order ⑧ products). Adjustable Dies Solid Round Dies ③Markings on the bevel of the die front face make it easy to determine the machining direction. ⑨ ④A recess in the die rear face allows a closer fit ofthe end face to the holder. Stable basis face ⑤Long life is achieved by the adoption of high-speed tool steel (HSS). ⑩ Cutting condition Die size［DPO S5 M6×1(20)］ Brass S45C Work Material Brass・S45C Cutting Speed Brass 5m/min・S45C 2m/min ⑪ Machine Vertical machining center with synchronous feed Cutting Fluid Water soluble cutting fluid JIS ⑩-33
