Built from high speed steel with a bright finish, it features three flutes and a plug chamfer for smooth thread entry and chip evacuation in through-hole and blind-hole applications. The H2 thread limit ensures close tolerance control for consistent insert fit. With a 1-inch thread length and an overall length of 2.5 inches, this tap is sized for compact work envelopes and standard hand-tapping operations. It is appropriate for machinists, maintenance technicians, and trade professionals performing thread repair or insert preparation in metal components.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in thread repair and thread insert prep work across industrial maintenance, HVAC equipment fabrication, and general metalworking. The 10-24 UNC configuration is common in light-duty fastener applications found in sheet metal assemblies, enclosures, and mechanical equipment. The plug chamfer provides moderate lead-in, making it suitable for both through holes and deeper blind holes where a bottoming tap is not required. Installation is typically performed by hand with a tap wrench, though it can be used in low-speed machine tapping setups with appropriate fixtures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e10-24 UNC thread form with H2 thread limit for controlled tolerance fit\u003c\/li\u003e\n  \u003cli\u003eThree-flute design promotes efficient chip evacuation during tapping\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides moderate lead-in for through holes and deeper blind holes\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction offers durability across ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eBright finish with 1-inch thread length and 2.5-inch overall length for compact applications\u003c\/li\u003e\n  \u003cli\u003eHelicoil reference number 3CPB for direct cross-reference to insert system tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with helicoil-style screw thread insert systems referencing Helicoil number 3CPB.

Before tapping, drill the correct STI tap drill size for 10-24 UNC insert installation as specified by the insert manufacturer. Apply cutting fluid appropriate to the workpiece material to extend tap life and reduce the risk of galling or breakage. Never force the tap against resistance — back off periodically to break chips and clear the flutes, especially in blind holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 10-24\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\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelicoil Reference Number\u003c\/strong\u003e: 3CPB\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: K007030AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728743104818,"sku":"K007030AS","price":29.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/27a7bd4253c1f44b80999d6ca9ad468b.jpg?v=1788695710","url":"https:\/\/voomisupply.com\/products\/hertel-k007030as-hand-sti-tap-10-24-unc-h2-3-flutes","provider":"Voomi Supply","version":"1.0","type":"link"}
