Made from high-speed steel (HSS), it combines the drilling and tapping steps into one tool, reducing setup time on the job. This type of tooling is used by machinists, pipefitters, and maintenance technicians who need to produce clean, accurately threaded holes in steel, aluminum, and similar materials without switching between a separate drill bit and tap. The HSS construction provides the hardness and heat resistance needed for production and service work.\u003c\/p\u003e\u003cp\u003eThe DT-3750-16-I is suited for hand-tap and machine-tap applications in light to medium-duty metalworking and field maintenance operations. It is commonly used when tapping into brackets, flanges, enclosures, and structural components where 3\/8-16 NC fasteners are specified. The combination format is particularly useful in repair and retrofit scenarios where drilling and tapping must be completed quickly in place or at a workbench.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCombination drill-and-tap design completes the 3\/8-16 NC thread in one pass\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction for durability across metal materials\u003c\/li\u003e\n\u003cli\u003eNational Coarse (NC) thread form — one of the most common fastener standards in North American trade work\u003c\/li\u003e\n\u003cli\u003eMinimum order quantity of 1, available as a single unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard combination tap drill for use in any hand or machine tapping operation requiring a 3\/8-16 NC threaded hole.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is typically used by machinists, pipefitters, and maintenance technicians working with drill presses, hand drills, or tapping machines. Secure the workpiece fully before drilling to prevent movement. Use appropriate cutting fluid for the base material to extend tool life and produce a cleaner thread. Follow applicable shop safety practices and wear eye protection during all drilling and tapping operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16 NC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Form\u003c\/strong\u003e: National Coarse (NC)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.715 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: EAGLE CUTTING TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: DT-3750-16-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233987264818,"sku":"DT-3750-16-I","price":30.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307622499.png?v=1780114120","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-dt-3750-16-i-3-8-16-nc-hss-combo-tap-drill","provider":"Voomi Supply","version":"1.0","type":"link"}
