Machined from submicron-grade solid carbide, this bar delivers the rigidity and wear resistance needed for tight-tolerance bores. It accepts a minimum bore diameter of 0.36 inches and reaches a maximum bore depth of 3 inches, making it suitable for a wide range of internal profiling and finishing passes. The right-hand cutting direction suits standard spindle rotation setups. With a corner radius range of 0.0050 to 0.0080 inches, this bar produces clean, controlled blends at bore transitions without stress risers.\u003c\/p\u003e\u003cp\u003eThis boring bar is used in job shops, production machining environments, and toolrooms where internal diameter work demands consistent dimensional accuracy. It is well suited to finishing operations on steel, stainless, aluminum, and similar machinable materials where a controlled corner radius is a print requirement. The 3\/8-inch shank diameter fits standard boring bar holders and quick-change tooling systems commonly found on manual and CNC turning equipment. The 4-inch overall length provides clearance for typical chuck and turret setups.\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\u003eCorner radius range of 0.0050 to 0.0080 inches for controlled bore-floor transitions\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.36 inches suits small to mid-range internal work\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 3 inches covers common production bore lengths\u003c\/li\u003e\n\u003cli\u003eRight-hand cut orientation for standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eBright finish coating  -  no additional coating interference with dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit boring bar for standard 3\/8-inch boring bar holders and quick-change tooling systems on CNC and manual turning equipment.

Power down and lock out the machine spindle before inserting or removing the bar from the holder. Minimize overhang beyond the holder to reduce chatter and deflection during the cut. Follow the machine tool manufacturer guidelines for tool clamping torque and runout inspection prior to cutting.\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: 0.36 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 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\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: 0.25 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: B3603000R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51986813878578,"sku":"B3603000R","price":96.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5ca31193404af6bb2bec8fc08fa5e467.jpg?v=1789986439","url":"https:\/\/voomisupply.com\/products\/accupro-b3603000r-corner-radius-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
