D（6）The D＝6 straight type is a specification available for shape*（round）only. It is not available for shapes +,-.. L（40.01）When LKC・LKZ is selected, select an L dimension of 40.01 or larger. Effective depth of scrap retention grooves（table below）. Perform shaped hole regrinding within the range of（Groove effective depth－1 mm）.

Can be used only for workpiece materials with tensile strengths up to 1177 N/mm2（120 kgf/mm2）. MT（workpiece material thickness）and C（clearance）are used as data for machining the scrap retention grooves. Specify the shaped hole dimensions（P・W・R）when selecting the button die finishing dimensions.
