It features a right-hand cutting direction with a minimum bore diameter of 0.2 inches and a maximum bore depth of 0.4 inches. The corner radius ranges from 0.0050 to 0.0080 inches, allowing machinists to produce controlled edge breaks and tight-tolerance radii at the base of bored features. The 1\/4-inch shank diameter and 2.5-inch overall length make this a compact tool suited for small-bore work on CNC turning centers and manual lathes.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is intended for production and job-shop environments where small-diameter internal features require consistent corner geometry. Typical applications include finish boring of hydraulic valve bodies, bearing pockets, and precision housings in ferrous and non-ferrous materials. The bright finish coating and submicron carbide substrate support performance in applications where tool deflection and edge wear must be minimized. Machinists and tool-room professionals select this bar for work where standard insert tooling cannot reach minimum bore diameters in this range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron solid carbide construction for improved hardness and wear resistance in small-bore applications\u003c\/li\u003e\n  \u003cli\u003eCorner radius range of 0.0050 to 0.0080 inches for controlled edge geometry at bore base\u003c\/li\u003e\n  \u003cli\u003eMinimum bore diameter of 0.2 inches supports tight-clearance internal features\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard CNC and manual lathe setups\u003c\/li\u003e\n  \u003cli\u003eBright finish coating on carbide substrate with no added coating thickness to affect tolerances\u003c\/li\u003e\n  \u003cli\u003eCompact 2.5-inch overall length with 1\/4-inch shank for rigid setup in small-bore toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide boring bar for use in standard 1\/4-inch bore bar holders and toolpost blocks on CNC turning centers and manual lathes performing right-hand internal turning operations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or tool-room technicians. The machine spindle must be stopped and all axes must be at a safe position before changing or setting tooling. Secure the shank in a properly sized 1\/4-inch boring bar holder and verify tool overhang is minimized to reduce deflection on small-diameter cuts. Do not exceed the maximum bore depth of 0.4 inches stated for this tool geometry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 0.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0050 to 0.0080 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\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: B200400R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51743537365298,"sku":"B200400R","price":43.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/83e5b11a77a71c41e1c005bdde65bfeb.jpg?v=1788848064","url":"https:\/\/voomisupply.com\/products\/accupro-b200400r-corner-radius-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
