Also called a gun tap, the spiral point design pushes chips forward ahead of the cutting edge, reducing clog risk in through-hole operations. Built from high speed steel with a bright, uncoated finish, this tap runs 2 flutes in a plug chamfer configuration, making it well suited for starting threads in pre-drilled through holes. The H11 thread limit indicates a slightly oversize tolerance — 0.005 inches oversize — which accommodates light plating or coating on finished fasteners. Machinists and toolroom techs reach for this style when threading steel, cast iron, and similar ferrous materials at moderate speeds.\u003c\/p\u003e\u003cp\u003eThis tap is intended for through-hole tapping operations on manual machines, drill presses, and CNC machining centers. The plug chamfer provides a gradual lead-in, making it a standard choice for production and repair tapping in metalworking shops, maintenance departments, and fabrication environments. Right-hand cutting direction matches standard right-hand threaded fastener specifications. The H11 oversize tolerance is particularly useful when the finished threaded hole will receive a plated or coated bolt where extra clearance prevents galling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward for cleaner through-hole threading\u003c\/li\u003e\n\u003cli\u003ePlug chamfer provides gradual thread lead-in for controlled starts\u003c\/li\u003e\n\u003cli\u003eH11 thread limit with 0.005-inch oversize accommodates plated fasteners\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction handles ferrous and general-purpose materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish for use with standard cutting fluids\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction matches standard UNC fastener specs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting 5\/16-18 UNC right-hand threads in through-hole applications on manual or CNC equipment.

Always secure the workpiece and use a properly sized tap holder or chuck to maintain axial alignment. Apply a suitable cutting fluid for the material being tapped to extend tool life and improve thread finish. Inspect the pre-drilled hole diameter against the recommended tap drill size for 5\/16-18 UNC before tapping to avoid tool breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\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, Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOversize\u003c\/strong\u003e: Yes, 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: JY4761185\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698034245938,"sku":"JY4761185","price":18.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/acdfc5660b7a9393adfe323e853ccea9.jpg?v=1788356987","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4761185-spiral-point-tap-5-16-18-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
