Machined from submicron-grade solid carbide, this bar delivers consistent edge integrity and wear resistance in ferrous and non-ferrous materials. It accepts a minimum bore diameter of 0.2 inches and reaches a maximum bore depth of 0.7 inches. The bright finish coating reduces friction and helps evacuate chips cleanly. With a 0.25-inch shank diameter and an overall length of 2.5 inches, the B200700R fits standard boring bar holders used in production and tool room environments. Machinists and CNC operators install this tool when a controlled corner radius is required at the base of a bored feature.\u003c\/p\u003e\u003cp\u003eThis boring bar is suited for light to moderate internal boring passes where a corner radius between 0.005 inches and 0.008 inches must be held consistently. Typical applications include finish-boring of bearing seats, counterbores, and precision housings in job shop and production settings. The right-hand cutting direction makes it compatible with standard spindle rotation on conventional lathes and CNC turning centers. It is sold as a single unit and is sized for use in small-bore work where rigidity and compact geometry matter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for high wear resistance and edge stability\u003c\/li\u003e\n\u003cli\u003eCorner radius range of 0.005 to 0.008 inches for controlled blend geometry at bore base\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for use with standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eBright finish coating reduces friction and aids chip flow\u003c\/li\u003e\n\u003cli\u003e0.25-inch shank diameter fits standard boring bar toolholders\u003c\/li\u003e\n\u003cli\u003eCompact 2.5-inch overall length suited for small-bore, close-clearance setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or production tooling solution for standard 0.25-inch boring bar holders used in CNC turning centers and manual lathes performing small-bore internal operations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC tooling technicians. Power down the machine and confirm the spindle is fully stopped before changing tooling. Secure the shank firmly in the boring bar holder to the appropriate clamping torque specified by the toolholder manufacturer. Verify tool overhang is minimized to reduce deflection, and confirm cutting direction and spindle rotation match before initiating a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.005 to 0.008 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 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: 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: Bright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0625 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: B200700R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51744216219954,"sku":"B200700R","price":43.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6814f02c2e5a9f1770cd14b7b3e2d62a.jpg?v=1788855099","url":"https:\/\/voomisupply.com\/products\/accupro-b200700r-corner-radius-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
