Made from high-molybdenum high-speed steel with a gold coating, it delivers strong wear resistance and heat tolerance for use in steel, cast iron, and similar ferrous materials. The 135-degree split drill point reduces thrust and improves centering without a pilot hole. With 2 flutes and a 15\/16-inch thread length, it cuts clean, accurate threads in one pass, reducing cycle time for machinists, maintenance techs, and fabricators working on production or repair applications.\u003c\/p\u003e\n\u003cp\u003eThis combination drill tap is suited for machine shop, maintenance, and light fabrication environments where drilling and tapping separate operations adds time or fixture complexity. It fits standard tap handles and machine setups configured for 5\/16-18 UNC threads. The 3.25-inch overall length accommodates standard chuck clearance in drill presses and CNC setups. It is appropriate for use in metals where high-speed steel tooling is rated, particularly low-to-medium carbon steels and softer alloys.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCombines drilling and tapping into a single operation, reducing setup and cycle time\u003c\/li\u003e\n  \u003cli\u003eHigh-molybdenum high-speed steel construction for improved heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003e135-degree split drill point for self-centering entry without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eGold coating reduces friction and extends tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e2-flute design promotes chip clearance during through-hole and blind-hole tapping\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC thread form for standard fastener applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard drill press chucks, CNC machining centers, and tapping heads configured for 5\/16-18 UNC thread applications in ferrous and compatible materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or maintenance technician familiar with combination drill-tap tooling. Secure the workpiece firmly before beginning the operation and use appropriate cutting fluid for the material being machined. Match spindle speed to the manufacturer recommendations for the material and tool diameter. Never back-drive the tool without confirming the setup is rated for reversible tapping to avoid thread damage or 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: 5\/16-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.9375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Size\u003c\/strong\u003e: G\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSplit Drill Point\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Molybdenum High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Gold\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: DT22HEX-5\/16-18\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717291180338,"sku":"DT22HEX-5\/16-18","price":103.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/12129996eae2660b56e372f4bdef1dbd.jpg?v=1788537902","url":"https:\/\/voomisupply.com\/products\/value-collection-dt22hex-5-16-18-combination-drill-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
