Designated as the 4ERN60 VKX style, it cuts a partial profile 60-degree thread form in a right-hand orientation. The insert carries a TiN coating applied via PVD process, which improves surface hardness and tool life on a range of workpiece materials. It covers a threads-per-inch range of 7 to 5 TPI and a metric pitch range of 3.50 to 5.00 mm, making it suitable for cutting multiple thread pitches without a tool change. Machinists and CNC operators working in production threading applications install this insert as a direct indexable replacement.\u003c\/p\u003e\u003cp\u003eThis insert is used in external threading operations on conventional and CNC turning centers in both job shop and production environments. The 4ER insert style fits compatible laydown threading toolholders. With a 12.70 mm inscribed circle and a 4.76 mm thickness, it seats in standard 4ER-series pockets. The 1\/2 inch inscribed circle dimension and a corner radius of 0.530 inches support consistent thread form accuracy across the covered TPI range. It is appropriate for threading mild steels, alloy steels, and similar machinable materials where TiN-coated carbide tooling is specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with PVD TiN coating for extended edge life\u003c\/li\u003e\n\u003cli\u003ePartial profile 60-degree thread form covers 7 to 5 TPI and 3.50 to 5.00 mm pitch\u003c\/li\u003e\n\u003cli\u003eRight-hand external threading orientation for standard lathe setups\u003c\/li\u003e\n\u003cli\u003e12.70 mm inscribed circle with 4.76 mm thickness fits standard 4ER laydown pockets\u003c\/li\u003e\n\u003cli\u003eSingle tooth per side geometry for controlled chip formation in threading passes\u003c\/li\u003e\n\u003cli\u003eVKX grade designation indicates manufacturer-specific carbide and coating specification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for standard 4ER-series laydown threading toolholders that accept a 12.70 mm inscribed circle, 4.76 mm thick indexable insert.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of threading inserts should be performed by a qualified machinist or CNC operator with the machine in a stopped, locked-out state per applicable lockout\/tagout procedures. Seat the insert fully in the toolholder pocket and torque the clamping screw according to the toolholder manufacturer specification. Inspect the insert pocket for chips or debris before seating. Never index or remove an insert while the spindle is in motion.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 4ER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: VKX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Partial Profile 60 Degree\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 7-5 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: 3.50 to 5.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 12.70 mm (1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 4.76 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.530 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Teeth Per Side\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VARGUS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 58561\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67908989288754,"sku":"58561","price":441.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f5380333568db365b8630eecf2a9f762_b36212d1-89b7-4b4b-b8f8-3c0be272deec.jpg?v=1791185372","url":"https:\/\/voomisupply.com\/products\/vargus-58561-threading-insert-4ern60-vkx-solid-carbide-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
