The bar cuts in the right-hand direction and handles a minimum bore diameter of 0.11 inches with a maximum bore depth of 0.3 inches. The 1\/8-inch shank diameter and 1.5-inch overall length make it well suited for small-bore applications where rigidity and dimensional accuracy are critical. A bright finish coating is applied to the flute and body. Corner radius range runs from 0.003 to 0.005 inches, allowing the operator to blend inside corners without leaving a sharp stress-concentration point.\u003c\/p\u003e\u003cp\u003eThis boring bar is used in CNC and manual turning operations where small internal diameters and controlled corner radii are required. Typical applications include precision bores in hydraulic components, medical device parts, instrumentation housings, and other small-diameter workpieces in ferrous and non-ferrous materials. The submicron carbide grade provides the hardness and edge retention needed for fine finishing passes at the bore wall and corner transition.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for high hardness and edge retention\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.11 inches for small-bore precision work\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 0.3 inches\u003c\/li\u003e\n\u003cli\u003eCorner radius range of 0.003 to 0.005 inches for controlled inside-corner blending\u003c\/li\u003e\n\u003cli\u003e1\/8-inch shank diameter for compatibility with standard small-bore toolholders\u003c\/li\u003e\n\u003cli\u003eBright finish coating on carbide body\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling selection for standard 1\/8-inch bore bar toolholders used in CNC turning centers and manual lathes requiring right-hand internal cutting tools.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed by a qualified machinist with the spindle fully stopped and the machine locked out per facility safety procedures. Secure the 1\/8-inch shank firmly in the toolholder to minimize overhang and deflection before taking any cut. Verify that the corner radius specification matches the part drawing requirement before beginning the boring pass. Follow the machine manufacturer guidelines for speed and feed selection appropriate to the workpiece material and depth of cut.\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: 0.11 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: B110300R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748129571122,"sku":"B110300R","price":55.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bfa584df5786b27239efd77555e053a3.jpg?v=1788889430","url":"https:\/\/voomisupply.com\/products\/accupro-b110300r-corner-radius-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
