SUMIDIA PCD / SUMIDIA Binderless PCD NPD10 / DA1090
¢ Features Lineup of SUMIDIA Binderless Small Diameter Boring Bars for internal boring (ø0.12" - ø0.16" / ø 3 - ø 4mm )
The use of a high-rigidity shank design and nano-polycrystalline diamond tip enables finishing of cemented carbide
*For internal boring of ø.197" / ø 4mm or more, NPD10 inserts and indexable holders can also be used. Refer to the chapter on "Boring Bars" in the General Catalog for details.
