Built from micrograin solid carbide, this right-hand-cut bar delivers tight dimensional accuracy in small-bore applications starting at 0.32 inches minimum bore diameter. The TiN (titanium nitride) finish coating extends tool life and reduces built-up edge in a range of workpiece materials. With a 3\/8-inch shank diameter and an overall length of 2.5 inches, this bar is sized for compact toolholding setups where rigidity and clearance are both critical. Machinists and toolroom technicians rely on this class of boring bar for finish-bore passes and close-tolerance hole sizing.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is suited for light to medium internal boring work in production and job-shop environments. Its 0.75-inch maximum bore depth makes it appropriate for shallow through-bores and blind holes in ferrous and non-ferrous materials. The right-hand cutting direction is compatible with conventional spindle rotation on standard CNC and manual lathes. The 3\/8-inch shank fits common boring bar holders and quick-change toolpost blocks used in general turning applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance in precision boring\u003c\/li\u003e\n  \u003cli\u003eTiN finish coating reduces friction and extends cutting edge life\u003c\/li\u003e\n  \u003cli\u003e0.32 inches minimum bore diameter suits small-bore internal turning\u003c\/li\u003e\n  \u003cli\u003e0.75 inches maximum bore depth for shallow blind and through-bore applications\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch shank diameter fits standard boring bar toolholders\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut direction for conventional spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-fit boring bar for turning centers and lathes equipped with 3\/8-inch boring bar holders accepting right-hand-cut solid carbide tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician with the machine powered down and the spindle fully stopped before toolholder changes. Ensure the shank is fully seated and clamped to the minimum recommended engagement depth in the toolholder to maximize rigidity and reduce chatter. Inspect the cutting edge for chipping before each use. Follow the machine manufacturer and toolholder specifications for setscrew torque and tool overhang limits.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 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: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1875 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-BB320750G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739608154418,"sku":"ACC-BB320750G","price":88.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c625f77ccd082dd5c571e16f5532d32.jpg?v=1788816871","url":"https:\/\/voomisupply.com\/products\/accupro-acc-bb320750g-boring-bar-0-32in-solid-carbide-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
