It is designed for internal boring operations on CNC lathes, manual lathes, and boring mills where precise hole finishing is required. The bar has a minimum bore diameter of 0.23 inches and a maximum bore depth of 1.25 inches, making it well suited for small, tight-tolerance bores. A bright finish coating is applied to the carbide body. The 5\/16-inch shank diameter and 2.5-inch overall length keep the tool compact for close-clearance setups. Machinists and toolroom technicians working on precision components are the primary users of this style of bar.\u003c\/p\u003e\u003cp\u003eThis boring bar is appropriate for production and job-shop environments requiring left-hand cutting geometry, typically used when the spindle rotation or workholding orientation demands a reverse-cut direction. It fits toolholders and boring bar sleeves sized for a 5\/16-inch shank. Applications include finishing drilled or reamed holes to a precise final diameter in metals and similar machinable materials where surface finish and dimensional accuracy are critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand cutting direction for reverse-spindle or specific fixturing applications\u003c\/li\u003e\n\u003cli\u003eSubmicron solid carbide construction for rigidity and extended tool life\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.23 inches enables work in small-diameter bores\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 1.25 inches suits shallow to medium-depth boring passes\u003c\/li\u003e\n\u003cli\u003eBright finish coating on carbide body\u003c\/li\u003e\n\u003cli\u003eCompact 5\/16-inch shank diameter and 2.5-inch overall length for close-clearance setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in toolholders and boring bar sleeves accepting a 5\/16-inch shank diameter.

Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Secure the shank firmly in the holder to the toolholder manufacturer's recommended clamping procedure to prevent chatter or pullout. Verify cutting direction matches spindle rotation before beginning a pass.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoring Bar Type\u003c\/strong\u003e: Boring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Left Hand\u003c\/li\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: 1.25 inches (1-1\/4 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\u003c\/strong\u003e: 2.5 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: 0.125 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: ACC-BBL2301250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729572266290,"sku":"ACC-BBL2301250","price":56.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/225d35aed49f0fccc823fd33f8daac7d.jpg?v=1788706284","url":"https:\/\/voomisupply.com\/products\/accupro-acc-bbl2301250-boring-bar-left-hand-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
