Belonging to the A04 series, this insert features Style A geometry and a GN chip breaker profile, making it suited for controlled chip evacuation during turning passes. The insert targets P-group workpiece materials, which covers carbon steels, alloy steels, and ferritic stainless steels. At 0.02 pounds per unit, it is a compact, single-use precision cutting tool installed by machinists and toolroom technicians working in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis turning insert is applied in external and internal turning operations where consistent chip control and edge integrity are required. The GN chip breaker geometry is optimized for the P workpiece material group, supporting reliable performance across a range of carbon and alloy steel applications. It fits A04 series toolholders designed to accept Style A inserts, making it a direct-fit replacement or standard restocking item for shops already running this toolholder platform.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbide substrate for wear resistance and thermal stability during steel turning\u003c\/li\u003e\n  \u003cli\u003eStyle A insert geometry compatible with A04 series toolholders\u003c\/li\u003e\n  \u003cli\u003eGN chip breaker profile for controlled chip formation and evacuation\u003c\/li\u003e\n  \u003cli\u003eRated for P-group workpiece materials including carbon and alloy steels\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.02 pounds per insert for easy indexing and handling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with A04 series toolholders accepting Style A turning inserts.

Use the appropriate torx or hex key specified by the toolholder manufacturer to secure the insert clamp to the recommended seating torque listed in the toolholder documentation. Inspect the insert pocket and shim for damage or contamination before seating a new insert. Do not mix insert styles or geometries within a toolholder designed for a specific seat configuration.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A04\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: GN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: VARGUS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 21989\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67911856292146,"sku":"21989","price":263.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e3d7e75618d880426220b309bbc89ab2.jpg?v=1791221969","url":"https:\/\/voomisupply.com\/products\/vargus-21989-turning-insert-carbide-style-a-series-a04","provider":"Voomi Supply","version":"1.0","type":"link"}
