It is manufactured from High-Speed Steel-E (cobalt-grade HSS) and finished with a Titanium Nitride (TiN) coating for improved wear resistance and tool life. The modified bottoming chamfer, with 2-3 chamfered threads, allows the tap to thread close to the bottom of blind holes. This tap operates in right-hand thread direction and carries a 2BX class of fit, making it suitable for precision threading tasks. Licensed machinists, tool and die makers, and maintenance technicians typically install or deploy this tool in production and repair environments.\u003c\/p\u003e\u003cp\u003eThis tap is suited for threading steel, stainless steel, and non-ferrous metals, covering material application codes P, M, and N. It performs in both blind hole and through-hole threading scenarios. The flute-by-diameter ratio is 3xD, which supports threading at appropriate depth-to-diameter ratios for the 1\/4-20 UNC thread standard. It belongs to the EMUGE Rekord Druck-S series, also identified under the trade name Druck 1-STEEL-SN-TiN, and is packaged individually with a minimum order quantity of 1.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 UNC thread size with right-hand thread direction\u003c\/li\u003e\n\u003cli\u003eHigh-Speed Steel-E (cobalt) construction with TiN coating for extended tool life\u003c\/li\u003e\n\u003cli\u003eModified bottoming chamfer with 2-3 chamfered threads for close-to-bottom threading in blind holes\u003c\/li\u003e\n\u003cli\u003e2BX class of fit for precision thread forming\u003c\/li\u003e\n\u003cli\u003eCompatible with steel, stainless steel, and non-ferrous metal workpieces\u003c\/li\u003e\n\u003cli\u003e3xD flute-by-diameter ratio supports controlled threading depth\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind hole and through-hole thread forming in steel, stainless steel, and non-ferrous metals.

Ensure the workpiece is securely fixtured and the pilot hole diameter matches the thread forming specifications for 1\/4-20 UNC before beginning. Cutting fluid or tapping lubricant appropriate for the workpiece material should be applied to reduce heat and tool wear. Coolant-through is not supported on this tap.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2BX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 2-3P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel-E (Cobalt)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.1496 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.6693 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.1811 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2550 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.1910 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steel; Stainless Steel; Non-Ferrous Metal\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: BU921400 (Rekord Druck-S)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: EMUGE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BU921400.5009\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EMUGE","offers":[{"title":"Default Title","offer_id":51972714266930,"sku":"BU921400.5009","price":88.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0b8d4e0166c58f792cd278f1c579b643.jpg?v=1789970260","url":"https:\/\/voomisupply.com\/products\/emuge-bu921400-5009-thread-forming-tap-1-4-20-unc-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
