Accupro ACC-BB120600 Boring Bar

Accupro ACC-BB120600 Boring Bar: 0.1200" minimum bore diameter and 0.6000" maximum bore depth, with a 3/16" (0.1875") shank and 2.0" overall length in a right-hand cut configuration. This solid-carbide tool is manufactured from submicron carbide for rigidity and wear resistance, delivering stable performance at the higher speeds typical in CNC lathes and small-diameter milling operations. Designed for internal boring of tight features, it provides precise bore depth control within micro-machining tasks and supports repeatable tolerances for small bore workpieces. The compact 2" length and slender 3/16" shank enable access to confined bores and blind holes, while the carbide substrate helps resist tool wear and maintain concentricity through extended use. Use cases include finishing small-diameter through holes and blind bores where consistent diameter and depth control are essential, especially in precision components and assemblies that demand tight tolerances and fine surface finishes.
