It has a minimum bore diameter of 0.025 inches and a maximum bore depth of 0.125 inches, making it well suited for small-diameter finish boring work. The right-hand cutting direction is standard for conventional lathe and machining center setups. The bright finish coating supports chip flow and helps maintain dimensional accuracy in tight bores. At 1.5 inches overall length with a 0.125-inch shank diameter, this bar fits compact toolholding systems and is designed for machinists who need reliable performance in miniature bore applications.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for use in CNC machining centers, manual lathes, and precision boring mills where small internal diameters must be held to close tolerances. It is appropriate for production and toolroom environments alike. Typical applications include small hydraulic component bores, instrument housings, medical device components, and other precision parts where a 0.025-inch minimum bore diameter is required. The submicron carbide grade provides the hardness and edge retention needed when cutting ferrous and non-ferrous materials at fine feeds and speeds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHelical boring bar geometry for improved chip evacuation in small-diameter bores\u003c\/li\u003e\n\u003cli\u003eSubmicron solid carbide construction for superior hardness and edge retention\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.025 inches for precision miniature bore applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut direction compatible with standard CNC and manual lathe setups\u003c\/li\u003e\n\u003cli\u003eBright finish coating promotes smooth chip flow and dimensional consistency\u003c\/li\u003e\n\u003cli\u003eCompact 1.5-inch overall length fits restricted toolholding envelopes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for precision boring applications requiring a 0.125-inch shank diameter and a minimum bore capability of 0.025 inches.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis boring bar should be installed by a qualified machinist following the toolholding system manufacturer's clamping procedures. Ensure all machine axes are at a complete stop and the spindle is powered off before changing tooling. Verify shank runout and secure the bar firmly in the holder to the appropriate clamping torque specified by the toolholder manufacturer — do not rely on generic values. Use appropriate cutting speeds and feeds for the workpiece material to avoid edge chipping on this carbide tool.\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\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.025 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 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\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: 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\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-HB025125\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729136288050,"sku":"ACC-HB025125","price":49.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0f97ea784017ff1dce25c453467e9984.jpg?v=1788700640","url":"https:\/\/voomisupply.com\/products\/accupro-acc-hb025125-helical-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
