Manufactured from high-speed steel (HSS), it delivers the hardness and heat resistance required for threading pipe-fitting ports in steel, cast iron, and similar ferrous materials. The tool features 4 flutes for efficient chip evacuation and a 45\/64-inch drill diameter with a 1-3\/8-inch thread length. At 4-3\/8 inches overall length, it is sized for standard drill press and hand-drilling applications. This type of tooling is commonly used by plumbers, pipefitters, HVAC technicians, and machinists who need to create NPTF-compliant threaded ports in manifolds, fittings, and equipment housings.\u003c\/p\u003e\n\u003cp\u003eThis combination drill tap is suited for creating 1\/2-14 NPTF tapered pipe thread ports in a range of materials encountered in plumbing, HVAC, and general mechanical work. NPTF threads are a dryseal standard, meaning the thread form itself creates a pressure-tight seal without a separate sealant when properly cut and mated. This makes the 00382325 appropriate for hydraulic, pneumatic, and fluid-handling applications where thread integrity is critical. It is packaged as a single unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDrills and taps a 1\/2-14 NPTF port in one pass, reducing setup time\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e4-flute design promotes chip evacuation and cleaner thread formation\u003c\/li\u003e\n  \u003cli\u003eNPTF thread standard produces dryseal pipe threads without relying solely on thread sealant\u003c\/li\u003e\n  \u003cli\u003e45\/64-inch drill diameter matched to 1\/2-14 NPTF tap geometry\u003c\/li\u003e\n  \u003cli\u003e1-3\/8-inch thread length suitable for standard pipe wall thicknesses\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in applications requiring 1\/2-14 NPTF tapered pipe thread ports.

The workpiece must be securely fixtured before operation to prevent walking and thread misalignment. Use appropriate spindle speeds for the material being tapped — speeds that are too high will shorten HSS tool life significantly. Always clear chips frequently when tapping deeper ports to prevent tool breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Size (Fractional)\u003c\/strong\u003e: 45\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Size (Decimal)\u003c\/strong\u003e: 0.7031 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 00382325\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699830751538,"sku":"00382325","price":186.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a632deba31a269f5aa3c122da53c7fba.jpg?v=1788381728","url":"https:\/\/voomisupply.com\/products\/value-collection-00382325-combo-drill-tap-1-2-14-nptf-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
