Built from micrograin solid carbide, this bar delivers superior rigidity and wear resistance compared to standard carbide grades, making it well suited for tight-tolerance applications. It accepts a minimum bore diameter of 0.49 inches and reaches a maximum bore depth of 2 inches. The 1\/2-inch shank diameter and 4-inch overall length (OAL) fit standard toolholders used on CNC lathes and manual lug boring setups. A TiN finish coating is applied to enhance surface hardness and extend tool life between regrinds. Right-hand cut geometry is standard.\u003c\/p\u003e\u003cp\u003eThis boring bar is used in metal-cutting operations where accurate, repeatable bore diameters are required. Typical applications include finish boring of bearing bores, hydraulic component housings, and close-tolerance through or blind holes in ferrous and non-ferrous materials. It is installed on CNC turning centers, engine lathes, and horizontal machining centers by machinists and tool-and-die professionals operating in job shop, production, and maintenance-and-repair environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for high rigidity and extended wear life\u003c\/li\u003e\n\u003cli\u003eTiN finish coating increases surface hardness and reduces tool wear\u003c\/li\u003e\n\u003cli\u003e0.49-inch minimum bore diameter suits small-bore finish applications\u003c\/li\u003e\n\u003cli\u003e2-inch maximum bore depth provides adequate reach for most short-bore work\u003c\/li\u003e\n\u003cli\u003e1\/2-inch shank diameter fits widely available standard toolholders\u003c\/li\u003e\n\u003cli\u003eRight-hand cut geometry for conventional turning setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct tooling addition for CNC turning centers and manual lathes accepting a 1\/2-inch shank boring bar with right-hand cut geometry.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified machinist. Power down and lock out the machine spindle before inserting or removing the boring bar from the toolholder. Confirm shank clamping torque meets the toolholder manufacturer specification and verify bar overhang does not exceed the toolholder guidelines to prevent chatter. Follow your shop safety procedures and applicable OSHA machine-guarding standards during setup.\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: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.49 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4 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: 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: 0.406 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: ACC-BB4902000G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51740782362930,"sku":"ACC-BB4902000G","price":125.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/30275ebc7b6af77c1d2d916d8f1d0b05.jpg?v=1788827398","url":"https:\/\/voomisupply.com\/products\/accupro-acc-bb4902000g-boring-bar-micrograin-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
