It cuts a 2-56 UNC thread at 56 threads per inch with a right-hand thread direction and a plug chamfer for progressive engagement. The tap is manufactured from HSS-E cobalt high-speed steel and finished with a titanium nitride (TiN) coating to extend tool life and reduce friction during the threading operation. With an overall length of 1.752 inches, a thread length of 0.441 inches, and a shank diameter of 0.141 inches, this tap is sized for small-diameter precision work. It carries a 2B class of fit and an H2\/H3 thread limit, making it suitable for standard tolerance threaded assemblies.\u003c\/p\u003e\u003cp\u003eThis tap is intended for through-hole threading applications in steel, and is suited for use in machine shop, production, and maintenance environments where consistent 2-56 UNC threads are required. The spiral point geometry pushes chips forward ahead of the cutting zone, which is an advantage in through-hole applications where chip evacuation is critical. It is well-suited for use in CNC tapping centers, drill presses with tapping attachments, and manual tapping operations. Part of the GUHRING Series 3916, it is sold individually with a minimum order quantity of one.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpiral point geometry promotes forward chip evacuation, reducing chip packing in through-hole applications\u003c\/li\u003e\n\u003cli\u003eHSS-E cobalt construction provides increased heat resistance and tool durability compared to standard HSS\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends service life in steel threading applications\u003c\/li\u003e\n\u003cli\u003ePlug chamfer allows progressive thread engagement for controlled cutting load\u003c\/li\u003e\n\u003cli\u003e2B class of fit with H2\/H3 thread limit for standard tolerance UNC threaded assemblies\u003c\/li\u003e\n\u003cli\u003eRight-hand, 3-flute design compatible with standard tapping equipment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for through-hole threading of 2-56 UNC threads in steel.

Ensure the workpiece is securely fixtured and the spindle is properly aligned before beginning the tapping cycle. Use appropriate tapping fluid or cutting oil for steel to reduce heat buildup and extend tool life. Do not reverse the tap under power until the cutting flutes have cleared the thread to avoid breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 2-56\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: 56\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 0.0179 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.752 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.441 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches\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\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: H2\/H3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Spiral Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: HSS-E Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN\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\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: 3916\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 9039160021840\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51749599641906,"sku":"9039160021840","price":48.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e8767999dd1549bc6450fdc8be91dbc0_67752532-9205-4d97-9eb5-181247dc5ccb.jpg?v=1788908160","url":"https:\/\/voomisupply.com\/products\/guhring-9039160021840-spiral-point-tap-2-56-unc-tin-hss-e","provider":"Voomi Supply","version":"1.0","type":"link"}
