It features a modified bottoming chamfer, which allows threading closer to the bottom of a blind hole than a standard taper tap while still providing better lead-in than a true bottoming tap. The four-flute straight-flute geometry provides rigidity and chip control in harder or abrasive materials. At 3-3\/8 inches overall length and finished with a FIREX coating, this tap is built for production and maintenance machining environments where tool life and thread quality matter.\u003c\/p\u003e\u003cp\u003eThis tap is suited for threading 1\/2-13 UNC threads in abrasive materials and cast iron, where cobalt construction provides the heat resistance and edge retention that high-speed steel alone cannot deliver. The FIREX coating adds additional surface hardness and reduces friction, making it appropriate for dry or minimal-lubrication machining setups. It fits standard machine tap holders and is used by machinists and tool-and-die professionals on manual mills, CNC machining centers, and drill presses equipped with tapping attachments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eModified bottoming chamfer for threading close to the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003eCobalt construction for improved heat resistance in abrasive and cast iron materials\u003c\/li\u003e\n\u003cli\u003eFIREX coating reduces friction and extends tool life in demanding applications\u003c\/li\u003e\n\u003cli\u003e4-flute straight-flute design provides rigidity and chip control\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, Class 2B thread fit with H5 and H6 thread limits\u003c\/li\u003e\n\u003cli\u003eSuitable for both blind-hole and through-hole threading operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting 1\/2-13 UNC threads in abrasive materials and cast iron.

Ensure the workpiece is securely fixtured and the tap is aligned perpendicular to the hole before engagement. Cutting fluid or coolant appropriate for the workpiece material should be applied unless the setup is specifically configured for dry tapping. Inspect the tap for wear or chipping before each use, as cobalt taps used in abrasive materials are subject to accelerated edge wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5, H6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/8 inches (3.381 inches decimal)\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\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: FIREX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Abrasive Material, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading, 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\u003eOversize\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.16 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 9039370127000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51731949748530,"sku":"9039370127000","price":88.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e100ed2a850e8e7c0baa390747b4ed03.jpg?v=1788737106","url":"https:\/\/voomisupply.com\/products\/guhring-9039370127000-machine-tap-1-2-13-unc-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
