Built from micrograin carbide, it delivers consistent cutting performance and edge retention in ferrous and non-ferrous materials. The bar accepts a minimum bore diameter of 0.625 inches and reaches a maximum bore depth of 3.5 inches, making it well suited for moderate-depth precision boring work. The 0.5-inch shank diameter provides rigid tool holding in standard boring bar holders, and the 7-inch overall length allows flexible reach without excessive overhang. Machinists and tool-room operators install this bar for finish and semi-finish boring passes where dimensional accuracy and surface finish quality are the primary objectives.\u003c\/p\u003e\u003cp\u003eThe ACC-TBB500 is appropriate for job shop, production, and maintenance machining environments. It fits applications where a compact, rigid boring bar is needed for through-bore and blind-bore work on steel, cast iron, aluminum, and similar workpiece materials. The bright finish coating reduces built-up edge tendencies on non-ferrous cuts. This bar is a single-piece unit suited for use in manual lathes, CNC turning centers, and horizontal boring mill setups where the 0.5-inch shank size is compatible with the existing tooling system.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin carbide construction for sharp, durable cutting edges\u003c\/li\u003e\n\u003cli\u003eRight-hand cut orientation for standard lathe and turning center setups\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.625 inches suits a wide range of bore sizes\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 3.5 inches for moderate-depth internal boring\u003c\/li\u003e\n\u003cli\u003e0.5-inch shank diameter fits standard boring bar holders\u003c\/li\u003e\n\u003cli\u003eBright finish coating reduces built-up edge on non-ferrous materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 0.5-inch boring bar holders on manual lathes, CNC turning centers, and horizontal boring mills requiring a right-hand cut internal boring bar.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or toolroom technician. Power down and lock out the machine spindle before mounting or removing the boring bar. Secure the shank firmly in the boring bar holder with adequate clamp length to minimize overhang and reduce chatter. Verify that the cutting edge is set on or slightly above centerline before beginning a cut.\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: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7 inches\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: Bright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.75 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-TBB500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732843462962,"sku":"ACC-TBB500","price":76.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4528b3e2836616982f7ea8dfc5867014.jpg?v=1788747445","url":"https:\/\/voomisupply.com\/products\/accupro-acc-tbb500-boring-bar-5-8-in-right-hand-micrograin","provider":"Voomi Supply","version":"1.0","type":"link"}
