Built from micrograin solid carbide stock, it delivers the rigidity and edge retention required for tight-tolerance bore work in steel, cast iron, stainless, and non-ferrous materials. The bar carries a TiAlN finish coating that extends tool life under dry or semi-dry cutting conditions. Minimum bore diameter is 0.49 inches, maximum bore depth is 2 inches, shank diameter is 0.5 inches, and overall length is 4 inches. Machinists and toolroom operators select this bar when dimensional accuracy and surface finish in a small-diameter bore are the primary requirements.\u003c\/p\u003e\u003cp\u003eThis boring bar is suited for light to medium-duty boring applications in production machining, job shop work, and toolroom environments. Its right-hand cutting direction makes it compatible with standard spindle rotation on conventional CNC turning centers and engine lathes. The 0.5-inch shank fits toolholders and boring bar blocks sized for that diameter, which are common on lathes in the mid-size range. It is appropriate for both roughing passes at moderate depths of cut and finish passes where surface finish and bore roundness are critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for high rigidity and wear resistance in demanding bore applications\u003c\/li\u003e\n\u003cli\u003eTiAlN coating provides thermal protection and extended edge life during dry or minimal-coolant cutting\u003c\/li\u003e\n\u003cli\u003e0.49 inch minimum bore diameter suits small-diameter internal features requiring tight tolerances\u003c\/li\u003e\n\u003cli\u003e2 inch maximum bore depth allows coverage of a wide range of common bore lengths with a single tool\u003c\/li\u003e\n\u003cli\u003eRight-hand cut configuration for use with standard spindle rotation on CNC and manual turning equipment\u003c\/li\u003e\n\u003cli\u003e0.5 inch shank diameter fits widely available toolholders and boring bar blocks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in toolholders and boring bar blocks accepting a 0.5 inch shank diameter on CNC turning centers and manual engine lathes with standard right-hand spindle rotation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Secure the shank in a properly sized boring bar holder or block, ensuring adequate overhang is minimized to reduce vibration and deflection during the cut. Confirm the spindle is fully stopped and the machine is in a safe state before loading or adjusting the tool. Follow the machine manufacturer guidelines and applicable shop safety procedures when setting tool offsets and establishing cut parameters.\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\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: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.40625 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-BB4902000A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51736777556274,"sku":"ACC-BB4902000A","price":125.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0384911fb06fb5f06a82412b441c5635_d66244d4-eaaf-4fa9-997b-50bec1611531.jpg?v=1788780259","url":"https:\/\/voomisupply.com\/products\/accupro-acc-bb4902000a-boring-bar-solid-carbide-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
