Manufactured to the G312GMN insert style in Series A4, this insert carries the KCU25 grade with a PVD-applied AlTiN coating for thermal resistance and extended tool life in demanding cutting environments. The neutral hand orientation makes it suitable for straight-in grooving without directional bias. With a cutting width of 0.3125 inches (7.94 mm) and a maximum depth of cut of 0.2460 inches (6.25 mm), the 4114341 is sized for medium-duty grooving work on steel, stainless, and similar materials common in general machining and production turning.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in production and job-shop turning environments where consistent groove geometry and surface finish are required. The GMN chip breaker geometry is suited for controlled chip evacuation during grooving passes, reducing the risk of chip packing in tight grooves. The 90-degree included angle and 0.0157-inch (0.41 mm) corner radius support clean groove walls and shoulders. It is installed by machinists and CNC operators in shops running Series A4 compatible grooving toolholders. The insert is a multi-use tool appropriate for both roughing and finishing grooving passes within its rated depth range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKCU25 solid carbide grade with PVD AlTiN coating for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eGMN chip breaker for controlled chip formation during grooving operations\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation for straight-in grooving applications\u003c\/li\u003e\n  \u003cli\u003e0.3125-inch (7.94 mm) cutting width with a maximum depth of cut of 0.2460 inches (6.25 mm)\u003c\/li\u003e\n  \u003cli\u003e0.0157-inch (0.41 mm) corner radius for defined groove geometry\u003c\/li\u003e\n  \u003cli\u003eSeries A4 insert seat size 8, compatible with corresponding A4 grooving toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Series A4 grooving toolholders accepting insert seat size 8.

Ensure the toolholder pocket and seating surfaces are clean and free of debris before seating the insert. Tighten the clamping screw to the toolholder manufacturer's specified torque using the appropriate Torx or hex key. Verify insert seating and runout before resuming cutting operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: G\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\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: GMN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 0.3125 inches (7.94 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2460 inches (6.25 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 0.2000 to 0.3000 inches (5.00 to 10.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Height\u003c\/strong\u003e: 0.2640 inches (6.71 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.181 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0157 inches (0.41 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 312\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-use Tool\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.043 pounds\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4114341\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727089959218,"sku":"4114341","price":744.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/04bb6f5a37fb9f294d3888cd04654e07.jpg?v=1788673135","url":"https:\/\/voomisupply.com\/products\/kennametal-4114341-grooving-insert-g312gmn-kcu25-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
