Part of the Series 3980 line, this 1\/2-13 UNC tap features a modified bottoming chamfer and a 40-degree helix angle that efficiently evacuates chips upward out of the hole during cutting. The tap is manufactured from cobalt high-speed steel and carries a TiN (titanium nitride) coating to extend tool life under demanding cutting conditions. With an H7 thread limit and a 0.0030-inch oversize allowance, it produces threads that accommodate standard tolerance fits. Overall length is 3.381 inches, and the tool weighs 0.062 pounds.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for blind hole applications where chip clearance is critical and through-hole evacuation is not possible. The fast flute style combined with the 40-degree right-hand helix promotes positive chip flow in ductile ferrous materials, including medium-carbon and alloy steels commonly encountered in production machining, maintenance, and repair operations. It is suitable for use in CNC machining centers, CNC lathes, and manual drill press setups where tapping attachments with tension-compression float are used. Licensed machinists and toolmakers are the primary users in manufacturing and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eModified bottoming chamfer allows threading close to the bottom of a blind hole\u003c\/li\u003e\n  \u003cli\u003e40-degree right-hand helix promotes upward chip evacuation in blind hole applications\u003c\/li\u003e\n  \u003cli\u003eCobalt HSS construction provides increased heat and wear resistance over standard HSS taps\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and extends tool life in steel cutting applications\u003c\/li\u003e\n  \u003cli\u003eH7 thread limit with 0.0030-inch oversize produces consistent tolerance fits\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute and right-hand thread configuration for standard forward-cutting operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for blind hole threading of alloyed and unalloyed steel.

Always secure the workpiece fully before tapping and confirm spindle speed and feed rate are appropriate for the material and tap diameter. Do not exceed the tap's rated thread limit by applying excessive torque. Power down and de-energize any CNC machine or tapping attachment before changing tooling.\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: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Fast\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: H7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmount Oversize\u003c\/strong\u003e: 0.0030 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloyed and Unalloyed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt HSS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\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\u003eSquare Size\u003c\/strong\u003e: 0.275 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3980\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.062 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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9039800127000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51748736008498,"sku":"9039800127000","price":83.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/957dc11d36b30993a372569ad74a3e67_c1a13070-7c43-421e-a07c-9742c969f6a4.jpg?v=1788897528","url":"https:\/\/voomisupply.com\/products\/guhring-9039800127000-spiral-flute-tap-1-2-13-unc-cobalt-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
