Machined from micrograin solid carbide stock, it delivers the rigidity and edge retention needed for tight-tolerance bore work. The bar features a TiAlN finish coating that improves heat resistance and extends tool life in ferrous and hardened materials. With a minimum bore diameter of 0.2 inches and a maximum bore depth of 0.5 inches, this bar suits small-diameter bore finishing and semi-finishing passes. The 0.25-inch shank diameter and 2.5-inch overall length make it compatible with standard small-bore toolholders. Right-hand cutting geometry is the standard configuration for conventional lathe rotation.\u003c\/p\u003e\u003cp\u003eThis boring bar is suited for production machining, tool rooms, and job shops where small-diameter internal features require consistent surface finish and dimensional accuracy. Typical applications include finishing bored holes in steel, cast iron, stainless, and similar machinable alloys. The compact shank diameter and short overall length favor Swiss-style and gang-tool setups as well as conventional gang turrets on small CNC lathes. Machinists and CNC operators working in aerospace, automotive, and general precision manufacturing will find this bar appropriate for tight-bore finish passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and superior edge retention in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eTiAlN finish coating improves thermal resistance and reduces built-up edge in ferrous cutting\u003c\/li\u003e\n\u003cli\u003e0.2-inch minimum bore diameter enables access to small internal features\u003c\/li\u003e\n\u003cli\u003e0.5-inch maximum bore depth suited for shallow precision bore finishing\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard lathe spindle rotation\u003c\/li\u003e\n\u003cli\u003e0.25-inch shank diameter fits common small-bore toolholding systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-fit boring bar for small-bore toolholders accepting a 0.25-inch shank diameter in CNC and manual turning applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before seating or removing the boring bar. Ensure the shank is fully seated and clamped to the minimum overhang required to reach bore depth, as excess overhang increases deflection and chatter risk. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when setting tool offsets.\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: 0.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 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: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: TiAlN\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-BB200500A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731458359602,"sku":"ACC-BB200500A","price":55.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd0b91d2ec62ee0b8c8446c098f3c2d4.jpg?v=1788731350","url":"https:\/\/voomisupply.com\/products\/accupro-acc-bb200500a-boring-bar-solid-carbide-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
