New SUMIDIA™ BINDERLESS DABX Series – Small Diameter Boring Bars

CBN/PCD cutting tools for high-precision turning of small holes (ø3mm+). Ideal for hard brittle materials like cemented carbide. Achieve superior accuracy.

Feature of DABX


Utilising Nano-polycrystalline diamond SUMIDIA™ BINDERLESS

  • Fine diamond particles, with a grain size of several tens of nanometres, are strongly and directly bonded without a binder under ultra-high-pressure and ultra-high-temperature environments, creating nano-polycrystalline diamond. Although it has higher hardness than single-crystal diamond, it lacks the cleavability which is a weak point of single-crystal diamond, displaying high toughness. With wear resistance exceeding that of conventional PCD, it maintains excellent machined surface quality and accuracy over long periods of machining of hard, brittle materials such as cemented carbide.

Supports small-diameter internal boring up to ø3mm and ø4mm

  • High-rigidity shank material and geometry realises excellent machined surface quality even in small-diameter internal boring of ø3mm and ø4mm.
