Built from cobalt high-speed steel and finished with a TiCN coating, this tap delivers heat and wear resistance in demanding cutting conditions. It features a 3-flute, right-hand spiral design with a 40-degree helix angle that efficiently evacuates chips upward out of the hole. The modified bottoming chamfer allows threading closer to the bottom of a blind bore than a standard bottoming tap. Thread specification is No. 2-64 UNF, Class of Fit 2B, with H2 and H3 thread limits. Overall length is 1.751 inches. This is a Series 3950 tap intended for use by machinists and tool-room professionals.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for blind hole threading in alloy steel and unalloyed steel workpieces. The right-hand flute and right-hand thread configuration make it a standard orientation for most CNC and manual tapping operations. The fast flute style improves chip flow at higher RPMs, which is common in production tapping on machining centers or drill presses. The TiCN coating reduces built-up edge and extends tool life when cutting harder steel grades. At 0.024 pounds, it is a small-format tap appropriate for precision work on small fastener threads.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 2-64 UNF right-hand thread, Class of Fit 2B with H2 and H3 thread limits\u003c\/li\u003e\n  \u003cli\u003eCobalt HSS construction for elevated heat resistance in steel cutting\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and extends tool life in abrasive materials\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes upward chip evacuation in blind holes\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer allows threading near the base of a blind bore\u003c\/li\u003e\n  \u003cli\u003eFast flute style supports higher-speed tapping operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for blind hole threading in alloy steel and unalloyed steel workpieces.

Power down and secure the workpiece before loading the tap into the holder. Use appropriate tapping fluid or cutting oil for steel to reduce heat and improve thread quality. Do not exceed the recommended cutting speed for the workpiece material, and avoid forcing the tap into the blind hole to prevent breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: No. 2-64\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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 and H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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\u003eFlute Style\u003c\/strong\u003e: Fast\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Alloy Steel, Unalloyed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.751 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\u003eNeck Length\u003c\/strong\u003e: 0.441 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.110 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: 3950\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.024 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: 9039500021840\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51969905164594,"sku":"9039500021840","price":46.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ac8d78f729ece7d10d813b40bb4d484f_c23cfd16-cf94-4fce-a268-ade5f6f9633a.jpg?v=1789952596","url":"https:\/\/voomisupply.com\/products\/guhring-9039500021840-spiral-flute-tap-unf-2b-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
