It features a Physical Vapor Deposition (PVD) AlTiN coating that improves wear resistance and thermal stability at the cutting edge. The insert measures 0.125 inches wide and 0.111 inches thick, with an inscribed circle of 0.5 inches. It carries a positive rake angle of 4 degrees, a relief angle of 3 degrees, and a honed cutting edge style. This insert is installed by machinists and CNC tooling specialists in milling operations where controlled chip formation and edge integrity are critical.\u003c\/p\u003e\u003cp\u003eThe 5134141 is engineered for primary workpiece materials including steel, stainless steel, superalloys, and titanium. It is suited to both roughing and finishing passes where a single-sided, neutral-hand insert with screw-clamping retention is required. The insert carries ANSI and ISO standard designations (KGIP0125N0189GD) and is compatible with KGEM cutter series bodies. Maximum depth of cut is 0.052 inches (1.33 mm). The GD chip breaker geometry supports positive cutting action in these material groups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade KCU45 solid carbide substrate with PVD AlTiN coating for extended tool life in steel and superalloy cutting\u003c\/li\u003e\n\u003cli\u003eKGIP series, ANSI\/ISO code KGIP0125N0189GD for standardized toolholder compatibility\u003c\/li\u003e\n\u003cli\u003ePositive rake angle (4 degrees) and honed cutting edge reduce cutting forces on difficult-to-machine materials\u003c\/li\u003e\n\u003cli\u003eSingle-sided, neutral-hand insert with screw-clamping holding method for secure, repeatable seating\u003c\/li\u003e\n\u003cli\u003eGD chip breaker geometry supports controlled chip evacuation in steel, stainless steel, superalloys, and titanium\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.052 inches (1.33 mm) suits fine to moderate stock removal passes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with KGEM series milling cutter bodies.

The machine spindle must be fully stopped and the machine placed in a locked-out, de-energized state before seating or replacing inserts. Use the appropriate torx or hex key to secure the clamping screw to the toolholder specification — do not overtighten, as this can fracture the carbide insert. Inspect the insert pocket and seating surface for debris before installing a fresh insert to ensure proper seating and runout.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: KCU45\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\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\u003eInsert Series\u003c\/strong\u003e: KGIP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: KGIP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Irregular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI\/ISO Code\u003c\/strong\u003e: KGIP0125N0189GD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.111 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.052 inches (1.33 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 3 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 4 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\u003eChip Breaker\u003c\/strong\u003e: GD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSided\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: KGEM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\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: 5134141\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51754587750706,"sku":"5134141","price":97.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6c6278cacb937d55df99409afaeff499.jpg?v=1788946864","url":"https:\/\/voomisupply.com\/products\/kennametal-5134141-milling-insert-kcu45-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
