Machined from submicron-grade solid carbide, this bar delivers rigidity and wear resistance in demanding cutting conditions. It handles a minimum bore diameter of 0.12 inches and reaches a maximum bore depth of 0.625 inches. The right-hand cutting direction suits standard CNC and manual lathe setups. With a 0.125-inch shank diameter and an overall length of 1.5 inches, this is a compact tool built for tight-tolerance work in production and toolroom environments.\u003c\/p\u003e\u003cp\u003eThe BB125 is suited for machining small bores in ferrous and non-ferrous materials where close tolerances and fine surface finishes are required. Its uncoated submicron carbide construction makes it appropriate for applications where coating buildup could affect dimensional accuracy. Typical use cases include boring small pin holes, valve seats, and precision cavities on CNC lathes, Swiss-type screw machines, and manual toolroom lathes. It is sold individually and is handled by machinists, toolroom technicians, and CNC operators.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for high rigidity and extended tool life in small-bore applications\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.12 inches for access to very small internal features\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 0.625 inches suits shallow-to-moderate cavity depths\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard lathe and CNC spindle rotation\u003c\/li\u003e\n\u003cli\u003eUncoated finish maintains dimensional precision where coating thickness is a concern\u003c\/li\u003e\n\u003cli\u003eCompact 1.5-inch overall length with 0.125-inch shank for use in small boring bar holders and turrets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and direct-fit boring bar for tooling systems accepting a 0.125-inch round shank, including standard small-bore bar holders and Swiss-type machine turrets.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Power down and lock out the machine before seating or removing the boring bar from its holder. Ensure the shank is fully seated and clamped to the specified holder torque per the toolholder manufacturer guidelines. Verify bore alignment and tool overhang before taking any cuts to avoid chatter or deflection in this small-diameter tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoring Bar Type\u003c\/strong\u003e: Radial Relief\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0625 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SCIENTIFIC CUTTING TOOLS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BB125\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52104634335538,"sku":"BB125","price":36.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3fa17e45430eb581a18e85d821efb4f1.jpg?v=1790072136","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-bb125-radial-relief-boring-bar","provider":"Voomi Supply","version":"1.0","type":"link"}
