Manufactured from high speed steel with a bright finish, it features an H2 thread limit and a plug chamfer for standard through-hole or deep blind-hole starting. Three flutes provide efficient chip evacuation in typical tapping operations. The tap measures 0.75 inches in thread length with a 2.125-inch overall length, keeping it compact for confined work areas. Machinists and maintenance technicians use this tap to prepare threaded bores that accept helical wire inserts, restoring or reinforcing thread integrity in metal workpieces.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for use in repair and production environments where STI threading is required ahead of helicoil-style insert installation. It is appropriate for ferrous and non-ferrous metals in both shop and field repair scenarios. The plug chamfer style makes it a versatile choice for most standard tapping applications where a starting taper is not required. The Helicoil reference number for this tap is 05CPA, which can assist in cross-referencing with insert kits and related tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-40 UNC thread form with H2 thread limit for controlled fit tolerances\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer for general-purpose through-hole and blind-hole tapping\u003c\/li\u003e\n  \u003cli\u003eThree-flute design promotes chip clearance during hand tapping\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides wear resistance across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright finish with 0.75-inch thread length and 2.125-inch overall length\u003c\/li\u003e\n  \u003cli\u003eHelicoil reference number 05CPA for cross-referencing with STI insert systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in STI tapping applications requiring a 5-40 UNC thread form.

Ensure the workpiece is securely fixtured and the bore is drilled to the correct STI tap drill size before tapping. Apply an appropriate cutting fluid for the workpiece material to extend tool life and improve thread quality. Never force the tap against hard resistance — back off periodically to break and clear chips.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5-40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelicoil Reference Number\u003c\/strong\u003e: 05CPA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K007009AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749154586930,"sku":"K007009AS","price":27.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/900628af733fdc079a85bc3b7fdea485.jpg?v=1788902714","url":"https:\/\/voomisupply.com\/products\/hertel-k007009as-hand-sti-tap-5-40-unc-h2-3-flutes","provider":"Voomi Supply","version":"1.0","type":"link"}
