It carries the IC830 grade with a PVD-applied TiAlN\/AlTiN\/TiN multilayer coating marketed under ISCAR's SumoTec designation. The 55-degree diamond shape (insert shape code D) with a positive rake and TF chip breaker makes this insert well-suited for finishing and semi-finishing passes. The corner radius measures 0.40 mm (0.0160 inches) and the inscribed circle is 12.70 mm (0.500 inches). Machinists and CNC operators in production and job-shop environments install this insert in compatible toolholders as a direct replaceable cutting edge.\u003c\/p\u003e\u003cp\u003eThis insert is rated for primary workpiece materials coded M, P, and S under ISO classification, covering stainless steels, carbon and alloy steels, and superalloys. It fits the ISCAR Isoturn series toolholding system and suits both roughing-light and finishing depths of cut up to 3.00 mm (0.118 inches). Typical install scenarios include shaft turning, facing, and contour operations on horizontal and vertical turning lathes in manufacturing, aerospace, and general metalworking shops. Right-hand cutting orientation is standard for this configuration.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC830 grade with PVD TiAlN\/AlTiN\/TiN SumoTec coating for extended tool life on steel and stainless\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape with positive rake for reduced cutting forces on finishing passes\u003c\/li\u003e\n\u003cli\u003eTF chip breaker geometry optimized for controlled chip formation at moderate feed rates\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut: 3.00 mm (0.118 inches)\u003c\/li\u003e\n\u003cli\u003eCompliant with ISO 13399 cutting tool data representation standards\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation; DNMG style with N clearance and M tolerance codes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in DNMG-style toolholders within the ISCAR Isoturn series.

Power down and lock out the machine spindle before changing inserts. Seat the insert firmly against the toolholder pocket locating surfaces and torque the clamping screw according to the toolholder manufacturer's specification. Inspect the seating pocket for chips or debris before installation to prevent insert rocking and premature edge failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC830\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: 55-degree Diamond (Code D)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: TF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN \/ AlTiN \/ TiN (SumoTec PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 15.50 mm (0.610 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 12.70 mm (0.500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 4.76 mm (0.187 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.40 mm (0.016 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 3.00 mm (0.118 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: M, P, S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DNMG 431-TF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3308144\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51727375958322,"sku":"3308144","price":297.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ce1024f25957b75d95a5d9c38f497016.jpg?v=1788676944","url":"https:\/\/voomisupply.com\/products\/iscar-3308144-dnmg431-tf-ic830-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
