This insert features a 35-degree diamond shape with a positive rake angle of 15 degrees and a 5-degree relief angle, making it well suited for light to moderate material removal in demanding applications. The inscribed circle measures 3\/8 inches, insert length is 16.61 mm (approximately 0.654 inches), and the corner radius is 1\/64 inches. The cutting edge is honed, and the chip breaker designation is FP. A screw-on holding method secures the insert in compatible toolholders. Licensed machinists and CNC operators are the primary users of this insert.\u003c\/p\u003e\u003cp\u003eThis insert is primarily targeted at machining stainless steel, superalloys, and titanium (ISO material codes M and S), with secondary suitability for cast iron, non-ferrous materials, and steel (ISO codes K, N, and P). Typical applications include turning, facing, boring, back turning, and back boring operations. The 35-degree diamond insert shape and positive rake geometry help reduce cutting forces when working with difficult-to-machine materials. The FP chip breaker geometry is designed to control chip formation during these operations. This insert meets ANSI and ISO standards for indexable cutting inserts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN PVD coating provides thermal and wear resistance for stainless steel, superalloy, and titanium machining\u003c\/li\u003e\n\u003cli\u003e35-degree diamond insert shape (VBMT) with positive rake for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge for improved edge stability in difficult materials\u003c\/li\u003e\n\u003cli\u003eFP chip breaker geometry for controlled chip formation in turning, facing, and boring\u003c\/li\u003e\n\u003cli\u003eScrew-on holding method for secure, repeatable insert indexing\u003c\/li\u003e\n\u003cli\u003e2 cutting edges per insert; neutral hand orientation for flexible toolholder use\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut: 1.25 mm (0.0492 inches)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in screw-on VBMT-style toolholders compatible with 3\/8-inch inscribed circle, 3\/16-inch thick diamond inserts.

Use the correct Torx or hex key as specified by the toolholder manufacturer when tightening the clamping screw — do not overtighten. Inspect the insert pocket and seating surface for chips or debris before seating a new insert. Verify insert orientation and cutting edge selection before resuming operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: VBMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: VBMT331FP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond 35 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCS10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: FP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 16.61 mm (0.6539 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inches (0.0156 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches (4.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.25 mm (0.0492 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 5 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 15 degrees (Positive)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Superalloys, Titanium (ISO M, S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron, Non-Ferrous, Steel (ISO K, N, P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplications\u003c\/strong\u003e: Turning, Facing, Boring, Back Turning, Back Boring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3769405\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51736471109938,"sku":"3769405","price":258.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/837585de1d750787be80385482c547d6.jpg?v=1788778110","url":"https:\/\/voomisupply.com\/products\/kennametal-3769405-vbmt331fp-turning-insert-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
