It cuts in a right-hand direction and is sized for tight-bore applications with a minimum bore diameter of 0.23 inches and a maximum bore depth of 0.8 inches. The 5\/16-inch shank diameter and 2.5-inch overall length (OAL) make it well suited for small-bore work on CNC lathes and manual turning centers where dimensional accuracy and surface finish are critical. The bright finish coating keeps the carbide substrate exposed for visual inspection and consistent chip flow.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is intended for machinists and toolroom professionals performing finish and semi-finish internal turning on metals and engineered materials. It is commonly used in production and job-shop environments on CNC lathes, turret lathes, and manual engine lathes. The corner radius range of 0.005 to 0.008 inches allows controlled blending at the base of bored features, reducing stress risers in the workpiece. It is sold individually and is appropriate where tight tolerances on small-diameter bores are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron solid carbide construction provides hardness and wear resistance for precision boring\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for standard lathe toolpost and boring bar holder setups\u003c\/li\u003e\n  \u003cli\u003eMinimum bore diameter of 0.23 inches supports small-bore applications\u003c\/li\u003e\n  \u003cli\u003eMaximum bore depth of 0.8 inches suitable for shallow-to-moderate bore depths\u003c\/li\u003e\n  \u003cli\u003eCorner radius range of 0.005 to 0.008 inches for controlled edge blending\u003c\/li\u003e\n  \u003cli\u003eBright finish coating for clear visual identification and consistent performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard boring bar holders accepting a 5\/16-inch round shank.

Secure the shank in a compatible boring bar holder with sufficient clamping engagement, typically a minimum of 1.5 times the shank diameter. Ensure the machine spindle is fully stopped and the toolpost is locked before inserting or adjusting the bar. Do not use this bar at cutting parameters that exceed the holder or machine manufacturer's recommended depth-of-cut and feed-rate guidelines for the shank size.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.23 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.005 to 0.008 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: Submicron Solid Carbide\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: 0.125 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: B230800R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51741307142450,"sku":"B230800R","price":60.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5d4716aff1d1cd4e62df7b2083a1d959.jpg?v=1788830682","url":"https:\/\/voomisupply.com\/products\/accupro-b230800r-corner-radius-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
