Built from submicron-grade carbide with a bright finish coating, this bar delivers consistent dimensional accuracy in tight-tolerance bores. It accepts a minimum bore diameter of 0.025 inches and reaches a maximum bore depth of 0.1 inches, making it well suited for small-diameter finish boring where rigidity and edge retention are critical. The right-hand cutting direction and 0.125-inch shank diameter suit standard quick-change and collet-style toolholding systems. Machinists and tool-and-die professionals specify this bar for fine-bore work in ferrous and non-ferrous materials.\u003c\/p\u003e\u003cp\u003eThis boring bar fits small-bore turning applications in production machining, toolroom, and job-shop environments. Its compact 1.5-inch overall length makes it practical for short-reach setups on gang-tool lathes, Swiss-style machines, and conventional engine lathes equipped with appropriate boring bar holders. Typical materials bored include aluminum alloys, brass, mild steel, and stainless steel where submicron carbide grain structure provides the edge stability needed for repeatable finish cuts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron-grade solid carbide construction for extended edge life in precision boring\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.025 inches suits very small internal features\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 0.1 inches for controlled short-reach operations\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard lathe rotation\u003c\/li\u003e\n\u003cli\u003eBright finish coating reduces built-up edge on non-ferrous and light ferrous cuts\u003c\/li\u003e\n\u003cli\u003e0.125-inch shank diameter fits common collet and quick-change boring bar holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or toolroom addition for setups requiring a 0.125-inch shank boring bar with right-hand cut geometry; confirm toolholder bore and clamping range before installation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists familiar with turning center toolholding systems. Power down or engage an E-stop on the machine and confirm spindle lock before inserting or removing the boring bar. Ensure the shank is clean and the toolholder bore is free of chips before clamping to maintain concentricity. Follow machine-tool manufacturer torque specifications for the clamping screws on the boring bar holder.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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: 0.1 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\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: MB025100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51752022999346,"sku":"MB025100","price":44.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe1e6c9ffcc7cb16840751c8f019339d.jpg?v=1788925287","url":"https:\/\/voomisupply.com\/products\/accupro-mb025100-boring-bar-submicron-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
