Manufactured from solid carbide with an AC830P CVD coating, this insert delivers consistent performance when machining stainless steel and carbon steel workpieces. The cutting width measures 0.1181 inches with a neutral lead angle and a corner radius of 1\/128 inch. The clamp-style holding method provides secure seating in compatible WCF toolholders, reducing vibration and improving surface finish on tight-tolerance cutoff applications. Sold individually, with a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for industrial turning operations where consistent cutoff width and edge stability are required across stainless steel and steel stock. The AC830P grade with CVD coating is well matched to ISO material codes M and P, covering austenitic stainless and general carbon or alloy steels. Typical applications include production turning environments where repeatable groove geometry and reliable chip control are critical. The WCF series design supports multi-use deployment across chamfering, cut-off, and grooving operations, reducing tooling inventory requirements on mixed-work lathes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with AC830P CVD coating for extended tool life on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003e0.1181-inch cutting width with neutral lead angle for straight, burr-minimized parting cuts\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 1\/128 inch reduces stress concentration at groove base\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert holding method ensures rigid, repeatable seating in WCF toolholders\u003c\/li\u003e\n  \u003cli\u003eMulti-use geometry supports chamfering, cut-off, and grooving from a single insert style\u003c\/li\u003e\n  \u003cli\u003eMaterial grades C5, C5A, and C6 cover a broad range of steel and stainless steel turning applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in WCF-series clamp-style toolholders compatible with insert size code 3.
