Manufactured from submicron solid carbide, it delivers the rigidity and edge retention needed for tight-tolerance bores in hardened materials and difficult-to-machine alloys. The bar has a minimum bore diameter of 0.05 inches, a maximum bore depth of 0.4 inches, and a corner radius range of 0.0030 to 0.005 inches. A bright finish coating is applied at the cutting end. With a 1\/8 inch shank diameter and an overall length of 1.5 inches, this bar is sized for micro-boring work on CNC lathes, boring mills, and manual turning centers.\u003c\/p\u003e\u003cp\u003eThis boring bar suits precision machining environments where small internal diameters and controlled corner radii are critical. Typical applications include bearing pocket finishing, hydraulic valve body bores, medical component machining, and aerospace part production. The right-hand cut orientation is compatible with standard lathe spindle rotation. Machinists and CNC operators working with tight print tolerances on bore geometry and surface finish will find this bar appropriate for finish passes and semi-finish passes in production and job shop environments alike.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction provides superior hardness and edge stability compared to standard carbide grades\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.05 inches enables access to very small internal features\u003c\/li\u003e\n\u003cli\u003eCorner radius range of 0.0030 to 0.005 inches allows controlled root geometry at bore transitions\u003c\/li\u003e\n\u003cli\u003eBright finish coating reduces friction and aids chip evacuation in small-bore conditions\u003c\/li\u003e\n\u003cli\u003eRight-hand cut direction for use with conventional lathe and boring mill spindle rotation\u003c\/li\u003e\n\u003cli\u003eCompact 1\/8 inch shank diameter and 1.5 inch overall length suited to micro-boring toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard production tooling option for 1\/8 inch bore bar toolholders used in CNC and manual turning applications requiring right-hand cut, small-diameter internal boring capability.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician. Secure the shank fully in the toolholder to the recommended overhang length per the machine manufacturer guidelines, as excessive overhang increases vibration risk on small-diameter carbide bars. Power down and lock out the spindle before installing or removing the boring bar. Avoid side loading or interrupted cuts beyond the design depth of 0.4 inches to prevent bar deflection or fracture.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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: 0.4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0030 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 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\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: B050400R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51749282808114,"sku":"B050400R","price":41.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3cf7e1f3bebc5884be27379903ebced0.jpg?v=1788904023","url":"https:\/\/voomisupply.com\/products\/accupro-b050400r-corner-radius-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
