Built from submicron-grade carbide with a bright finish, this bar delivers the rigidity and edge retention needed for tight-tolerance work in ferrous and non-ferrous materials. It has a minimum bore diameter of 0.045 inches and a maximum bore depth of 0.1 inches, making it well suited for micro-bore applications where standard tooling cannot reach. The 1\/8-inch shank diameter keeps the setup compact, and the 1-1\/2-inch overall length fits most small-bore tool holders and CNC turret positions.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for use in CNC turning centers, manual lathes, and mill-turn machines where close-tolerance internal diameters are required. It is a right-hand cut tool, positioned for standard forward-feed boring passes. Typical applications include finish boring of small hydraulic ports, bearing bores, and precision-fit housings in production machining environments. Machinists and tooling specialists working in job shops or production facilities will find this bar appropriate for high-precision, short-depth bores.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction provides high rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eBright finish coating reduces built-up edge in non-ferrous and light ferrous cuts\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.045 inches enables micro-bore capability\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 0.1 inches suits shallow, close-tolerance internal features\u003c\/li\u003e\n\u003cli\u003eRight-hand cut geometry for standard forward-feed boring operations\u003c\/li\u003e\n\u003cli\u003e1\/8-inch shank diameter fits compact tool holders and small-bore turret positions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct tooling selection for 1\/8-inch shank boring bar holders used in small-bore turning and mill-turn applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and the tool holding system is locked out before changing or seating the boring bar. Set shank overhang to the minimum length needed for the bore depth to maximize rigidity and minimize deflection. Confirm tool holder bore diameter and clamping style are compatible with a 1\/8-inch round shank before mounting.\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: 0.045 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.1 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\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: MB045100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51755605655858,"sku":"MB045100","price":44.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/06c26e2600bc5e92d47831a6ede3fb79.jpg?v=1788956761","url":"https:\/\/voomisupply.com\/products\/accupro-mb045100-boring-bar-submicron-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
