It carries the VTX manufacturer grade with a PVD-applied TiAlN coating, which improves wear resistance and extends tool life across a wide range of workpiece materials. The insert produces a 10 TPI Stub Acme thread profile per ANSI B1.8:1988 and features a 29-degree included angle. With a 3\/8-inch (9.53 mm) inscribed circle and a thickness of 3.60 mm, it seats in compatible 3IR-style toolholders. Machinists and CNC operators installing threaded lead screws, jack screws, or power transmission components are the primary users of this insert.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal threading operations on a broad range of materials, including steel, stainless steel, cast iron, non-ferrous metals, and high-temperature alloys, as reflected by its universal primary workpiece material classification (H, K, M, N, P, S material codes). It is commonly used in production shops, job shops, and maintenance machining environments where Stub Acme thread forms are specified. The 3IR insert style is compatible with standard 3IR internal threading toolholders. This SKU is sold individually but requires a minimum order quantity of 10 pieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with PVD TiAlN coating for extended wear life\u003c\/li\u003e\n\u003cli\u003eRight-hand internal Stub Acme thread form, 10 TPI, per ANSI B1.8:1988\u003c\/li\u003e\n\u003cli\u003e29-degree included angle matches Stub Acme thread geometry\u003c\/li\u003e\n\u003cli\u003e3IR insert style with 3\/8-inch inscribed circle fits standard 3IR toolholders\u003c\/li\u003e\n\u003cli\u003eUniversal material compatibility across steel, stainless, cast iron, non-ferrous, and superalloy workpieces\u003c\/li\u003e\n\u003cli\u003eVTX grade optimized for consistent thread quality in CNC and manual turning applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 3IR-style internal threading toolholders that accept inserts with a 3\/8-inch (9.53 mm) inscribed circle and a 3.60 mm thickness.

Before changing inserts, power down the machine and lock out the spindle per applicable shop lockout\/tagout procedures. Use the correct torque wrench and insert clamp screws specified by the toolholder manufacturer  -  do not overtighten, as solid carbide inserts are brittle and can crack under excess clamping force. Verify insert seating and tool geometry offset in the machine controller before taking the first threading pass.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 3IR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 3\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: VTX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Stub Acme\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 29 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\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: 3.60 mm\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (H, K, M, N, P, S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI B1.8:1988, ISO 9001:2008\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 52295\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67911732461874,"sku":"52295","price":322.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/270f01e83163aaf00978840a0888e35d_6ae360ba-ab31-442d-a666-30b90dfddd47.jpg?v=1791218136","url":"https:\/\/voomisupply.com\/products\/vargus-52295-threading-insert-10-tpi-stub-acme-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
