It features a 0.12 inch minimum bore diameter, a 0.004 inch corner radius, and a maximum bore depth of 0.5 inches. The bright, uncoated finish preserves dimensional accuracy at the cutting edge. With a 3\/16 inch shank diameter and a 2 inch overall length, this bar is suited for small-bore, tight-tolerance work where surface finish and dimensional control are critical. Machinists and toolroom technicians working with hardened materials, composites, or high-silicon aluminum will find the PCD (polycrystalline diamond) tip appropriate for demanding finishing passes.\u003c\/p\u003e\u003cp\u003eThis boring bar is used in production and toolroom environments where small internal diameters must be held to tight tolerances. It is well matched to finish-boring operations on parts made from abrasive or non-ferrous materials such as aluminum alloys, copper, brass, and carbon fiber composites. Right-hand cut orientation makes it compatible with conventional spindle rotation on standard turning equipment. It is typically applied in applications requiring a controlled corner radius break rather than a sharp edge at the bore entrance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDiamond-tipped (PCD) cutting edge for extended tool life in abrasive and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e0.12 inch minimum bore diameter enables small-bore internal finishing\u003c\/li\u003e\n\u003cli\u003e0.004 inch corner radius for precise, consistent edge geometry\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 0.5 inches suits shallow to medium-depth bores\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish maintains close dimensional tolerances at the tip\u003c\/li\u003e\n\u003cli\u003eRight-hand cut configuration for standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling option for boring bar holders accepting a 3\/16 inch round shank on CNC and manual turning centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before seating or adjusting the boring bar in the tool holder. Ensure the shank is clamped securely with appropriate set screws to the specified holder bore; inadequate clamping on small-shank boring bars can cause chatter and tool pull-out. Do not exceed the recommended maximum bore depth of 0.5 inches, as overhang beyond rated depth increases deflection and reduces surface finish quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Diamond-Tipped (PCD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0625 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241601\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: PCD-B120500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51972012998962,"sku":"PCD-B120500","price":188.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/139369a4c233ad869d1353535d333f81_0946483c-1269-4cdf-a0c7-807d56e6b07c.jpg?v=1789960951","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-pcd-b120500-boring-bar","provider":"Voomi Supply","version":"1.0","type":"link"}
