With a minimum bore diameter of 0.3 inches and a maximum bore depth of 1.5 inches, this bar handles tight-tolerance small-bore work where rigidity and vibration resistance are critical. The bright finish coating protects the substrate and reduces built-up edge. A 5\/16-inch shank diameter and 2.5-inch overall length make it compatible with standard boring bar holders and small-bore tool blocks. Machinists and tool-and-die professionals use this bar on CNC lathes and manual turning centers where precise, repeatable finish cuts are required.\u003c\/p\u003e\n\u003cp\u003eThis helical boring bar is suited for small-diameter internal boring in production machining, toolroom, and job-shop environments. The right-hand cutting direction makes it appropriate for conventional lathe setups where the spindle rotates counterclockwise when viewed from the tailstock. It is commonly selected for ferrous and non-ferrous materials where submicron carbide grain structure delivers extended tool life and consistent surface finish in finishing and light semi-finishing passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron-grade solid carbide construction for superior hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eHelical boring bar geometry reduces chatter and improves chip evacuation in small bores\u003c\/li\u003e\n  \u003cli\u003eMinimum bore diameter of 0.3 inches for tight small-bore applications\u003c\/li\u003e\n  \u003cli\u003eMaximum bore depth of 1.5 inches suits typical shallow-to-medium internal turning jobs\u003c\/li\u003e\n  \u003cli\u003eBright finish coating minimizes friction and resists built-up edge\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for standard lathe and CNC turning center setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard toolroom boring bar for use in turning centers and manual lathes equipped with 5\/16-inch boring bar holders or compatible small-bore tool blocks.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool turret or holder is locked before installing or removing the bar. Secure the shank firmly in the holder to the depth recommended by the holder manufacturer to minimize overhang and reduce vibration. Do not exceed the maximum bore depth specification, as excessive overhang increases deflection and risk of tool breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBoring Bar Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3125 inches (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\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: 0.125 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: ACC-HB3001500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51736415535410,"sku":"ACC-HB3001500","price":56.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7aedee945124288337584905bcb0097.jpg?v=1788777836","url":"https:\/\/voomisupply.com\/products\/accupro-acc-hb3001500-helical-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
