Part of the Snap Tap series, it is manufactured from micrograin solid carbide with a CP500 grade designation and a PVD-applied TiAlN\/TiN coating for extended wear resistance. The insert features a 60-degree included angle and a 1.25mm pitch, making it suited for right-hand external ISO thread profiles. At 0.1366 inches thick with a 3\/8-inch inscribed circle, it seats into standard 16ER-style toolholders. Machinists and CNC operators in production and job-shop environments install this insert for threading operations on stainless steel and similar work materials.\u003c\/p\u003e\u003cp\u003eThis insert is engineered primarily for stainless steel workpieces (material code M) where PVD-coated micrograin carbide provides the combination of edge sharpness and heat resistance needed for consistent thread quality. The A2 chipbreaker geometry assists with chip control during threading passes. The right-hand orientation suits standard external threading operations in typical turning setups. It is sold individually per package with a minimum order quantity of two pieces, making it appropriate for shops that rotate inserts regularly as part of a planned tooling maintenance program.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide substrate with CP500 grade designation for wear resistance in stainless steel applications\u003c\/li\u003e\n\u003cli\u003ePVD-applied TiAlN\/TiN coating for thermal protection and extended edge life\u003c\/li\u003e\n\u003cli\u003e1.25mm ISO pitch with 60-degree included angle for standard external ISO thread profiles\u003c\/li\u003e\n\u003cli\u003eA2 chipbreaker geometry assists chip control during threading passes\u003c\/li\u003e\n\u003cli\u003eRight-hand cut orientation for conventional external threading setups\u003c\/li\u003e\n\u003cli\u003e3\/8-inch inscribed circle fits standard 16ER-style toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for 16ER-style laydown threading insert seats used in standard external ISO threading toolholders and boring bars configured for right-hand operation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator with the machine in a locked-out, zero-energy state before insert indexing or replacement. Use the correct torque wrench and insert screw specified by the toolholder manufacturer to secure the insert — avoid over-tightening, which can fracture carbide. Verify insert seating and toolholder cleanliness before resuming cuts. Follow applicable shop safety procedures and manufacturer tooling guidelines when setting cutting parameters.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16ER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: CP500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\/TiN (PVD)\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: ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: 1.25mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\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: A2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1366 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0070 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel (Code M)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge to Theoretical Edge Length\u003c\/strong\u003e: 0.0310 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFace of Insert to Tip Centerline\u003c\/strong\u003e: 0.0310 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Snap Tap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: 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: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 00077782\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559451197746,"sku":"00077782","price":82.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/133597ac60a172cb9000a6b330ff1153.jpg?v=1786432779","url":"https:\/\/voomisupply.com\/products\/seco-00077782-threading-insert-1-25mm-iso-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
