Built from solid carbide with a VK8 grade and a PVD-applied AlTiN\/TiN coating, this insert delivers consistent thread form and extended tool life in demanding turning applications. The 60-degree included angle conforms to NPT thread geometry, and the right-hand cut orientation suits standard lathe setups. At a thickness of 0.1420 inches and an inscribed circle of 3\/8 inch, it seats securely in compatible MACH TT series toolholders. Licensed machinists and CNC lathe operators working in metalworking and pipe-fitting production are the primary users of this insert.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external NPT threading operations on pipe and fitting stock in both production shop and job shop environments. The NPT thread standard makes it applicable to plumbing, HVAC, and industrial piping components where tapered pipe thread forms are required. The solid carbide substrate and AlTiN\/TiN PVD coating support use in ferrous and non-ferrous materials at elevated cutting speeds. The laydown seating style provides a stable insert orientation and repeatable indexing during high-volume threading runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide VK8 grade substrate for wear resistance in continuous and interrupted threading cuts\u003c\/li\u003e\n\u003cli\u003eAlTiN\/TiN PVD coating reduces friction and extends insert life at elevated surface speeds\u003c\/li\u003e\n\u003cli\u003e60-degree included angle matches NPT external thread form geometry\u003c\/li\u003e\n\u003cli\u003eLaydown insert style with 3\/8 inch inscribed circle for secure toolholder engagement in MACH TT series holders\u003c\/li\u003e\n\u003cli\u003eRight-hand cut orientation for standard lathe and CNC turning center setups\u003c\/li\u003e\n\u003cli\u003eNo chipbreaker geometry  -  suited for threading applications where chip control is managed by feed and speed selection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with MACH TT series toolholders that accept laydown-style threading inserts with a 3\/8 inch inscribed circle.

Use the correct torque wrench or insert clamp tool specified by the toolholder manufacturer  -  do not overtighten the clamping screw, as this can fracture the carbide insert. Inspect the insert pocket and clamping surfaces for debris before seating the insert. Index or replace the insert at the first sign of thread-form deviation or surface finish degradation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: Laydown\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: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 3\/8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1420 inches (3.62 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\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: VK8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\/TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MACH TT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.003 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: 30252\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67911453573426,"sku":"30252","price":352.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bb0e73c83623658f55254d791e1353f4.jpg?v=1791210920","url":"https:\/\/voomisupply.com\/products\/vargus-30252-laydown-threading-insert-external-npt-3-8","provider":"Voomi Supply","version":"1.0","type":"link"}
