It features a right-hand cutting direction, a minimum bore diameter of 0.18 inches, and a maximum bore depth of 1.5 inches. The 3\/16-inch shank diameter and 2.5-inch overall length make this bar well suited to small-bore work where rigidity and tool clearance are critical. The bright finish coating reduces friction at the cutting edge without altering the dimensional geometry of the bar. Machinists and tool-and-die professionals working on CNC lathes and machining centers will find this bar appropriate for tight-tolerance bores in ferrous and non-ferrous materials.\u003c\/p\u003e\u003cp\u003eThis boring bar fits applications requiring small internal bore diameters in production machining, toolroom work, and precision repair operations. Its submicron carbide grade provides the hardness and wear resistance needed for consistent performance in interrupted cuts or abrasive workpiece materials. The right-hand configuration suits standard spindle rotation setups on most CNC and manual lathes. It is a single-piece solid carbide bar without replaceable inserts, making it appropriate where setup simplicity and tool profile repeatability are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for high hardness and edge retention\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.18 inches for small-bore internal turning\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 1.5 inches suitable for shallow to mid-depth bores\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eBright finish coating reduces cutting friction without dimensional impact\u003c\/li\u003e\n\u003cli\u003e3\/16-inch shank diameter with 2.5-inch overall length for compact tool holding\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide helical boring bar for use in standard tool holders accepting a 3\/16-inch shank diameter on CNC lathes and manual turning centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this boring bar should be performed by a qualified machinist familiar with internal turning operations. Secure the shank fully in the tool holder to the recommended grip length to minimize overhang and chatter. Ensure the machine spindle is fully stopped and the lathe or machining center is powered off before changing or adjusting tooling. Do not exceed the maximum bore depth of 1.5 inches, as excessive overhang beyond the supported shank length increases deflection risk and can cause tool breakage.\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: 0.18 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: 0.1875 inches (3\/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\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-HB1801500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738469368114,"sku":"ACC-HB1801500","price":42.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0ce1a0f8bb213b139dc9c8721ee9308c.jpg?v=1788799946","url":"https:\/\/voomisupply.com\/products\/accupro-acc-hb1801500-helical-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
