Machined from submicron-grade solid carbide, this boring bar delivers rigidity and wear resistance in demanding cutting conditions. It features a right-hand cutting direction, a minimum bore diameter of 0.05 inches, and a maximum bore depth of 0.3 inches. The bright finish coating reduces friction and helps maintain dimensional accuracy. With a 1\/8-inch shank diameter and a 1-1\/2-inch overall length, this bar is suited for small-bore applications where reach and concentricity matter. It is installed by machinists working on CNC lathes, boring mills, and manual turning centers.\u003c\/p\u003e\u003cp\u003eThe B050300R is used in small-bore finishing and semi-finishing operations across industries including aerospace, medical device manufacturing, and precision tooling. The corner radius range of 0.003 to 0.005 inches allows the technician to match part geometry requirements while minimizing stress concentration at the bore corner. This bar is a strong fit for tight-clearance bores where a standard boring bar cannot reach or maintain the required surface quality.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for high rigidity and extended tool life\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard lathe and boring mill setups\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.05 inches enables machining of very small internal features\u003c\/li\u003e\n\u003cli\u003eCorner radius range of 0.003 to 0.005 inches for controlled blending at bore corners\u003c\/li\u003e\n\u003cli\u003eBright finish coating reduces built-up edge and aids chip flow\u003c\/li\u003e\n\u003cli\u003eCompact 1\/8-inch shank diameter fits small-bore toolholders and collet chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in toolholders and collet chucks accepting a 1\/8-inch shank diameter, suitable for CNC and manual lathes and boring mills configured for small-bore internal turning operations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or toolroom technician. Secure the shank fully in the toolholder and verify runout before cutting. Ensure the machine spindle is fully stopped and all motion has ceased before inserting or removing the boring bar. Follow shop safety protocols and machine-specific operating procedures when setting cutting parameters.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoring Bar Type\u003c\/strong\u003e: Corner Radius\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: 0.05 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.3 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\u003eCorner Radius\u003c\/strong\u003e: 0.003 to 0.005 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: Bright\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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: B050300R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733774008626,"sku":"B050300R","price":55.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3bbf18fb60fc23aef4563470aa95b10f_5feeeb63-f5a9-4a16-bc13-3a280265e842.jpg?v=1788759141","url":"https:\/\/voomisupply.com\/products\/accupro-b050300r-corner-radius-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
