Built from submicron-grade carbide and coated with AlTiN (aluminum titanium nitride) for heat and wear resistance, this bar handles tight-tolerance bore work in hardened steels, stainless alloys, and cast iron. It features a right-hand cut geometry with a 3\/16 inch shank diameter and a 2 inch overall length. The 0.14 inch minimum bore diameter and 0.4 inch maximum bore depth make it suited for small, shallow bores where rigidity and edge integrity are critical. Machinists and toolroom technicians reach for this bar when finish quality and dimensional accuracy in confined bore diameters are the priority.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is used in production and job-shop turning environments for finishing and semi-finishing small-diameter internal bores. Typical applications include bore sizing on hydraulic valve bodies, small housings, bushings, and precision fixtures. The AlTiN coating extends tool life at elevated cutting speeds and elevated temperatures, making it effective in dry and near-dry machining setups. The right-hand cut orientation is standard for conventional OD-turning toolpost setups on most manual and CNC lathes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron solid carbide construction for high rigidity and edge retention in small-bore applications\u003c\/li\u003e\n  \u003cli\u003eAlTiN finish coating provides heat resistance and extended tool life in ferrous and hardened materials\u003c\/li\u003e\n  \u003cli\u003e0.14 inch minimum bore diameter enables access to tight internal diameters\u003c\/li\u003e\n  \u003cli\u003e0.4 inch maximum bore depth suits shallow through and blind bore finishing passes\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut geometry compatible with standard lathe tooling setups\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch shank diameter fits common small-bore toolholders and boring bar blocks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in toolholders and boring bar blocks that accept a 3\/16 inch shank diameter.

Secure the shank fully within the toolholder to the manufacturer-recommended engagement depth before beginning any cuts. Ensure the machine spindle is fully stopped and the lathe is powered down before changing or setting tooling. Verify bore alignment and runout before taking finishing passes to avoid bell-mouthing or taper in the finished bore.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 0.14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 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: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0625 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: B140400A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51746700263730,"sku":"B140400A","price":47.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e4029c42e6622174fbad2a793d8de76a.jpg?v=1788872973","url":"https:\/\/voomisupply.com\/products\/accupro-b140400a-boring-bar-0-14-in-submicron-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
