Built from cobalt high-speed steel and coated with titanium nitride (TiN), it delivers extended tool life and reduced friction in demanding production and maintenance environments. The tap features a 1\/2-13 UNC thread form, 4 flutes, and a plug chamfer for standard through-hole entry. Overall length is 3.381 inches with a shank diameter of 0.367 inches. The H11 thread limit provides a slight oversize of 0.005 inches to account for material springback. This tap is typically installed by machinists, maintenance technicians, and tool and die professionals.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for through-hole threading operations in both production and repair applications. The cobalt construction and TiN finish make it appropriate for use in harder or more abrasive materials where standard HSS taps wear prematurely. Rated for use in aluminum, gray cast iron, malleable iron, non-ferrous metals, spheroidal iron, stainless steel, and steel. Right-hand thread direction. Coolant-through capability is not included in this design. Part of the Guhring Series 3986 tap line.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt high-speed steel construction for improved heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and extends tool life in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides 3-5 thread lead-in for standard through-hole entry\u003c\/li\u003e\n  \u003cli\u003eH11 thread limit with 0.005 inch oversize accommodates material springback\u003c\/li\u003e\n  \u003cli\u003e4-flute design provides chip control across a broad material range\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral point construction pushes chips ahead of the tap during cutting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading in aluminum, gray cast iron, malleable iron, non-ferrous metals, spheroidal iron, stainless steel, and steel.

Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill size for 1\/2-13 UNC before tapping. Apply appropriate cutting fluid for the workpiece material to reduce heat buildup and improve thread quality. Inspect the tap for wear or chipping before each use and replace if cutting edges are degraded.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\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\u003eAmount Oversize\u003c\/strong\u003e: 0.005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.381 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.367 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.062 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3986\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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9039860127000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51748585668914,"sku":"9039860127000","price":71.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f80e66bd16877b81f97d1171902e8c77_2ec3427e-2c8a-4196-878a-4811d8ba1bf8.jpg?v=1788895432","url":"https:\/\/voomisupply.com\/products\/guhring-9039860127000-spiral-point-tap-1-2-13-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
