Manufactured from submicron-grade solid carbide with a bright finish coating, this bar delivers the rigidity and edge retention needed for precise bore work at tight tolerances. It accepts a minimum bore diameter of 0.04 inches and reaches a maximum bore depth of 0.1875 inches (3\/16 inches). With a 1\/8-inch shank diameter and an overall length of 1.5 inches, the ACC-HB040187 is sized for compact setups on CNC lathes, live tooling heads, and small-bore turning applications. Right-hand cutting orientation is standard.\u003c\/p\u003e\u003cp\u003eThis boring bar is suited for precision machining shops, toolrooms, and production environments where small internal diameters require consistent finish and dimensional accuracy. Its submicron carbide construction makes it a reliable choice for ferrous and non-ferrous materials where tool deflection and chatter must be minimized. Machinists and CNC operators working on small-bore components such as hydraulic fittings, valve bodies, and instrumentation parts will find this tool well-matched to those requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for high rigidity and extended tool life\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.04 inches enables work on extremely small internal features\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 0.1875 inches (3\/16 inches) for shallow internal passes\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard lathe and CNC turning setups\u003c\/li\u003e\n\u003cli\u003eBright finish coating reduces built-up edge on non-ferrous and light ferrous materials\u003c\/li\u003e\n\u003cli\u003eCompact 1\/8-inch shank diameter fits common small-bore toolholders and collet systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for 1\/8-inch shank boring bar holders used in CNC lathes, live tooling, and manual turning setups requiring right-hand helical boring bars.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the control is in an E-stop or locked-out state before mounting or removing the boring bar. Secure the shank fully within the toolholder to the manufacturer-specified minimum clamping engagement to prevent pullout during cutting. Verify correct tool offset entry in the control before initiating any bore cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoring Bar Type\u003c\/strong\u003e: Helical\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: 0.04 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 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: 0.0625 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-HB040187\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731415335218,"sku":"ACC-HB040187","price":39.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64d1ee3c6f7ab06dc9a3c68a533bfd77.jpg?v=1788730763","url":"https:\/\/voomisupply.com\/products\/accupro-acc-hb040187-helical-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
