Built from micrograin solid carbide, this bar offers the rigidity and edge retention required when holding tight tolerances on small-diameter bores. The TiAlN finish coating improves heat resistance and extends tool life in ferrous and hardened materials. With a 0.18-inch minimum bore diameter and a 0.25-inch shank, this bar fits compact toolholders used in small-part machining. Overall length is 2.5 inches, making it suitable for short-reach applications where overhang must be minimized to control vibration and chatter.\u003c\/p\u003e\u003cp\u003eThis boring bar is suited for production and job-shop environments where small internal diameters demand a rigid, wear-resistant tool. Typical applications include finish boring of through-holes and blind holes in ferrous alloys, stainless steel, and other materials compatible with TiAlN coatings. The right-hand cutting direction is standard for conventional lathe setups running with normal spindle rotation. Maximum bore depth is 0.6 inches, making this bar well-matched to short-depth features in turned components. It is used by machinists and toolroom professionals working in precision turning operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction provides superior rigidity and edge retention compared to standard carbide grades\u003c\/li\u003e\n\u003cli\u003eTiAlN finish coating improves thermal resistance and extends tool life in ferrous and hardened materials\u003c\/li\u003e\n\u003cli\u003e0.18-inch minimum bore diameter enables entry into very small internal features\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard lathe spindle rotation\u003c\/li\u003e\n\u003cli\u003e0.25-inch shank diameter fits common small-bore toolholders and turret blocks\u003c\/li\u003e\n\u003cli\u003e2.5-inch overall length limits overhang for reduced vibration in short-reach bores\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in toolholders and turret blocks accepting a 0.25-inch round shank boring bar. Suitable for CNC and manual turning applications requiring a right-hand cutting direction with a minimum bore entry of 0.18 inches and a maximum depth of 0.6 inches.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Secure the shank fully within the toolholder to the recommended minimum engagement depth before tightening to prevent pullout under cutting load. Ensure the cutting edge is set on center height for accurate bore geometry. Always bring the spindle to a complete stop and confirm the machine is in a safe state before inserting or removing boring bars from the turret or toolpost.\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: 0.18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.6 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\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: 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-BB180600A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730770297138,"sku":"ACC-BB180600A","price":58.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/30f6fb2dc8fd0c1f2d67a779f515b45b.jpg?v=1788722569","url":"https:\/\/voomisupply.com\/products\/accupro-acc-bb180600a-boring-bar-micrograin-carbide-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
