The insert carries an ISO designation of TCMT 09 02 08-UM 4415 and features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability at elevated cutting speeds. With a neutral hand orientation, a 0.2188-inch inscribed circle, and a 0.0313-inch corner radius, this insert suits medium-to-finish turning passes where dimensional control and surface finish consistency are priorities. Licensed machinists and CNC turning center operators are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning steel and similar ferrous materials in both production and job-shop environments. The TCMT-UM chip breaker geometry is intended for medium cutting conditions where chip control across a range of feeds is required. The clamp and screw holding method is compatible with standard TCMT-style toolholders used on CNC lathes and turning centers. The 4415 grade designation reflects a coated carbide substrate optimized for steel-cutting applications with ISO material code P and secondary code K coverage.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: TiCN, Al2O3, TiN for wear and thermal resistance\u003c\/li\u003e\n  \u003cli\u003eTriangular insert shape (T) with TCMT geometry and neutral hand\u003c\/li\u003e\n  \u003cli\u003e0.0313-inch corner radius suited for medium to finish turning passes\u003c\/li\u003e\n  \u003cli\u003eTCMT-UM chip breaker geometry for consistent chip control in steel cutting\u003c\/li\u003e\n  \u003cli\u003eClamp and screw holding method for rigid, positive seating in toolholder\u003c\/li\u003e\n  \u003cli\u003eManufacturer grade 4415 optimized for primary workpiece material: steel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard TCMT-style toolholders compatible with the TCMT 09 02 08 insert seat geometry.

Seat the insert fully into the toolholder pocket and secure using the appropriate clamp or torx screw per the toolholder manufacturer specification. Inspect the insert seat for chips or contamination before seating a new insert, as debris under the insert can cause premature edge failure or dimensional shift. Handle carbide inserts with care to avoid chipping the cutting edges prior to use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TCMT 09 02 08-UM 4415\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (T)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 4415\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.2188 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0313 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.0938 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: UM (TCMT-UM series)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Clamp and Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material Code\u003c\/strong\u003e: K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.74 inches L x 1.54 inches W x 0.44 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 (minimum order quantity: 10)\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: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8020980\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51738480967986,"sku":"8020980","price":199.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9bd5a1ab9f2260cfc2c9d27c27ae4a5c_7c0a0433-f8e8-4612-b8c0-4fb0384112b6.jpg?v=1788800094","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-8020980-turning-insert-tcmt-09-02-08-um-4415","provider":"Voomi Supply","version":"1.0","type":"link"}
