Built from high-speed steel (HSS) with a steam oxide finish, this tap produces clean, accurate threads at a 3\/8-16 UNC specification. The spiral point geometry pushes chips forward ahead of the cutting zone, making it well-suited for threading through-holes where chip evacuation is critical. With 3 flutes, an H3 thread limit, and a 2B\/3B class of fit, this tap delivers consistent dimensional accuracy for standard tolerance threading work. It is used by machinists, maintenance technicians, and trade professionals working with metallic and general-purpose workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for through-hole threading operations in production and maintenance environments. The plug chamfer provides a moderate lead-in, making it appropriate for starting threads in a pre-drilled hole without requiring a taper tap first. At 2.9375 inches overall length with a 1.25-inch thread length, it fits standard tap holders and tapping heads used in manual and machine tapping setups. Typical applications include threading fastener holes in steel, aluminum, and other general-purpose metals in fabrication, repair, and assembly work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC right-hand thread for standard unified coarse fastener applications\u003c\/li\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward, ideal for clean through-hole threading\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides durability across general-purpose materials\u003c\/li\u003e\n  \u003cli\u003eSteam oxide coating reduces friction and improves wear resistance during cutting\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit with 2B\/3B class of fit for standard tolerance requirements\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer allows direct starts in pre-drilled through-holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for general-purpose through-hole threading applications requiring a 3\/8-16 UNC right-hand thread.

Always ensure the workpiece is properly secured and the pre-drilled hole is sized to the correct tap drill diameter before beginning. Use appropriate cutting fluid for the workpiece material to extend tap life and improve thread quality. Do not exceed the tap's rated capacity for the material being threaded, and back off periodically to break chips when tapping manually.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16 UNC\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: 16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Spiral Point\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\/3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.9375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.381 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Steam Oxide\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\u003eMaterial Application\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 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: TITAN USA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TT91071S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51754811687218,"sku":"TT91071S","price":21.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9dd8b4da93b107b05bdd3f18f23291bc_a71d8b92-38fb-4f77-aa74-ba3946ab9065.jpg?v=1788948795","url":"https:\/\/voomisupply.com\/products\/titan-usa-tt91071s-spiral-point-plug-tap-3-8-16-unc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
