Built from submicron-grade solid carbide with a bright finish, it delivers the rigidity and edge retention needed when cutting in confined bores. The bar has a minimum bore diameter of 0.04 inches and a maximum bore depth of 0.1 inches, making it suited for precision micro-boring work. The 1\/8-inch shank diameter keeps the tool compact, and the 1-1\/2-inch overall length fits standard small-bore toolholding setups. Machinists and tool-and-die shops working on precision components install this bar where dimensional accuracy in small bores is critical.\u003c\/p\u003e\u003cp\u003eThis boring bar is used in CNC turning centers, manual lathes, and mill-turn machines where very small internal diameters must be finished to close tolerances. Its right-hand cutting direction suits standard right-hand boring configurations. The submicron carbide substrate resists micro-chipping and holds a sharp edge longer than standard carbide grades, which is an advantage when boring hardened or abrasive workpiece materials. Typical applications include instrument components, hydraulic valve bodies, and any small-diameter bore requiring a controlled surface finish.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide substrate for improved edge retention and resistance to micro-chipping\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.04 inches for precision micro-boring operations\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 0.1 inches suited to shallow, tight-tolerance bores\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard boring setups\u003c\/li\u003e\n\u003cli\u003eBright finish coating provides a smooth surface for reduced friction during cutting\u003c\/li\u003e\n\u003cli\u003eCompact 1\/8-inch shank diameter fits small-bore toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use boring bar for toolholders accepting a 1\/8-inch round shank, compatible with standard small-bore boring bar holders used on CNC lathes and mill-turn centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool clamping and overhang. Secure the shank firmly in the toolholder to minimize overhang and reduce vibration, which is critical at small bore diameters. Ensure the machine spindle is fully stopped and all axes are at a safe home position before changing or adjusting tooling. Do not exceed the maximum bore depth rating, as doing so can cause tool deflection and bore geometry errors.\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\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.04 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 (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches (1-1\/2 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\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: MB040100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51754373054770,"sku":"MB040100","price":48.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2c4cdcff15a2c934e0a089b1d2e7a4ba.jpg?v=1788944823","url":"https:\/\/voomisupply.com\/products\/accupro-mb040100-boring-bar-submicron-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
