Built from High-Speed Steel-E-PM (powder metallurgy HSS) and finished with a Titanium Nitride (TiN) coating, this tap handles demanding materials including steel, stainless steel, hardened steel, and chilled cast iron. The 4-flute, plug chamfer geometry drives chips forward ahead of the cut, making it well suited for through-hole work where chip evacuation is straightforward. With a 2B class of fit and H5\/H6 thread limit, it produces threads within standard tolerance for general fastener assembly in production and maintenance machining environments. Licensed machinists, tool-room operators, and industrial maintenance technicians are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for through-hole threading operations in ferrous materials. The plug chamfer provides a moderate lead-in, making it appropriate for both CNC tapping centers and hand-tapping setups where controlled torque can be applied. Applications span general fabrication shops, MRO environments, and production lines where 1\/2-13 UNC threaded holes are common. The TiN coating extends tool life and reduces friction across repeated use cycles. Coolant-through is not supported; standard flood or brush-applied cutting fluid is appropriate for this tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point geometry drives chips forward, optimized for through-hole threading\u003c\/li\u003e\n  \u003cli\u003eHigh-Speed Steel-E-PM base material provides elevated wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and extends tool life in steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer allows moderate lead-in suitable for CNC and hand-tapping applications\u003c\/li\u003e\n  \u003cli\u003e2B class of fit with H5\/H6 thread limit for standard tolerance threaded fastener holes\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction for conventional tapping operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading in steel, stainless steel, hardened steel, and chilled cast iron.

Always ensure the spindle or tapping attachment is aligned with the hole centerline before engaging the tap to avoid tap breakage or thread distortion. Use an appropriate cutting fluid for the workpiece material — sulfurized oil or water-soluble coolant is common for steel and stainless applications. Coolant-through is not supported by this tool; external lubrication must be applied. Always secure the workpiece and verify correct drill hole diameter prior to tapping.\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\u003eThread Pitch\u003c\/strong\u003e: 0.0769 inches\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Style\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\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steel, Stainless Steel, Hardened Steel, Chilled Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.331 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.5 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\u003eMaterial\u003c\/strong\u003e: High-Speed Steel-E-PM (Powder Metallurgy HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\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: 3992\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 9039920127000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51728494657842,"sku":"9039920127000","price":78.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/26984840b38552a0ac4391a9bfb5d630.jpg?v=1788692125","url":"https:\/\/voomisupply.com\/products\/guhring-9039920127000-spiral-point-tap-1-2-13-unc-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
