It features a 35-degree diamond (rhombic) insert shape with a positive rake angle of 20 degrees and a 7-degree relief angle, giving it a sharp, free-cutting geometry suited to light, accurate passes. The TiAlN PVD coating on AH725 grade carbide delivers high wear resistance across a broad range of workpiece materials. With a corner radius of 0.40 mm (1\/64 inch) and a maximum depth of cut of 0.50 mm, this insert is engineered for finishing where tight tolerances and fine surface finishes are the priority.\u003c\/p\u003e\n\u003cp\u003eThe VCMT110304-PSF PSF chip breaker geometry is optimized for finishing cuts on steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It is well suited to external turning, facing, boring, back turning, and back boring applications in both production and job-shop environments. The neutral hand orientation and screw-holding method make it compatible with standard VCMT-style toolholders. Licensed machinists and CNC operators in aerospace, general machining, and precision manufacturing will find this insert applicable across a wide range of turning scenarios.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAH725 grade TiAlN PVD coating for high wear resistance on steel and stainless steel (P15, P30, M15, M30)\u003c\/li\u003e\n  \u003cli\u003ePSF chip breaker geometry optimized for finishing operations with positive rake\u003c\/li\u003e\n  \u003cli\u003e35-degree diamond insert shape provides a sharp cutting angle for low cutting forces\u003c\/li\u003e\n  \u003cli\u003e0.40 mm corner radius for fine surface finish and close-tolerance work\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert for extended tool life per unit\u003c\/li\u003e\n  \u003cli\u003eMulti-use geometry supports turning, facing, boring, back turning, and back boring\u003c\/li\u003e\n  \u003cli\u003ePositive side clearance and chamfered\/honed cutting edge style reduce built-up edge risk\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard VCMT-style screw-lock toolholders conforming to ANSI insert code VCMT221 and ISO insert code VCMT110304.

Seat the insert fully against the toolholder pocket and torque the clamping screw to the toolholder manufacturer's specified value using a calibrated torque driver. Inspect the insert seat and clamping screw for wear or debris before seating a new insert. Verify tool offset data in the machine controller after each insert change before resuming cuts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: VCMT221\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: VCMT110304\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: V - Diamond (Rhombic) 35 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AH725\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PSF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.40 mm (0.0157 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 11.20 mm (0.882 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Width\u003c\/strong\u003e: 6.35 mm (0.250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 6.35 mm (0.250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3.18 mm (0.125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 2.80 mm (0.110 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.50 mm (0.0197 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 20 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloys, Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P15, P30, M15, M30, K25, K30, S15, S25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.022 pounds\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: TUNGALOY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6864951\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TUNGALOY","offers":[{"title":"Default Title","offer_id":52073309831474,"sku":"6864951","price":292.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b933a9726f214d64c3bbfb03af3a8e44.jpg?v=1790050381","url":"https:\/\/voomisupply.com\/products\/tungaloy-6864951-vcmt110304-psf-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
