Built with a micrograin solid carbide tip brazed to a steel shank, this tool bit delivers consistent edge retention and wear resistance during boring, chamfering, and turning. The right-hand cutting direction and AR-style geometry follow the AR-8 industry standard, making it a straightforward drop-in for compatible toolholders. The shank measures 0.5 inches wide by 0.5 inches tall with an overall length of 3.5 inches. A 1\/32-inch nose radius is ground into the tip, providing a controlled finish on workpiece surfaces. Machinists and tool-and-die professionals working on manual or CNC lathes are the primary installers.\u003c\/p\u003e\u003cp\u003eThis tool bit is suited for general-purpose lathe work in job shops, maintenance machining, and production turning environments. It handles boring, chamfering, and external turning on ferrous and non-ferrous materials where a square shoulder profile is required. The AR form factor is widely used in both manual engine lathes and turret lathes. The micrograin carbide tip grade is appropriate for finishing and semi-finishing cuts where edge sharpness and tip integrity matter most.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide tip for improved edge retention and surface finish quality\u003c\/li\u003e\n\u003cli\u003eAR-style geometry conforming to industry standard AR-8\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard lathe orientation\u003c\/li\u003e\n\u003cli\u003e0.5 inch by 0.5 inch shank for secure toolholder seating\u003c\/li\u003e\n\u003cli\u003e1\/32 inch nose radius for controlled workpiece finish\u003c\/li\u003e\n\u003cli\u003eSuitable for boring, chamfering, and turning operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard fitment for AR-8 single point toolholders accepting a 0.5 inch square shank, as specified by industry standard AR-8 geometry.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists following standard lathe tooling setup procedures. Secure the tool bit firmly in the toolholder before operating the machine, and verify cutting edge height relative to the workpiece centerline before taking a cut. Power down and lock out the lathe before changing or adjusting tool bits. Inspect the carbide tip for chipping or wear before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Bit Style\u003c\/strong\u003e: AR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: AR-8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Bit Type\u003c\/strong\u003e: Square Shoulder Turning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Material Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Length\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.03125 inches (1\/32 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Application\u003c\/strong\u003e: Boring, Chamfering, Turning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 21-MG\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728864149810,"sku":"21-MG","price":22.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9f7944b48c9203871aec921b49bf786f.jpg?v=1788697094","url":"https:\/\/voomisupply.com\/products\/accupro-21-mg-single-point-tool-bit-rh-ar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
