Manufactured from powdered metal high-speed steel (HSS-E-PM) and coated with TiN-T26, it delivers extended tool life in demanding tapping applications. With a bottoming chamfer of 1.5 to 2 thread pitches, it reaches near-bottom thread depths in blind holes. The H5 thread limit and 2BX class of fit ensure a controlled, accurate thread form. Coolant-through capability supports high-speed, production-volume tapping. Overall length is 3.543 inches with a thread length of 0.551 inches.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for blind hole threading in ferrous materials, specifically steel and stainless steel, corresponding to ISO material application codes P and M. The bottoming chamfer geometry makes it a practical choice for holes with limited runout depth, such as those found in machined components, fastener bosses, and structural assemblies. It is installed by machinists and tool-and-die professionals using CNC machining centers, tapping heads, or manual tap handles in controlled production or job-shop environments. The trade name InnoForm 2-VA\/E-SN-IKZ-PM-TiN-T26 identifies the full series designation in EMUGE documentation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming (chipless) operation eliminates chip evacuation concerns in blind holes\u003c\/li\u003e\n  \u003cli\u003ePowdered metal HSS-E-PM construction provides superior wear resistance over conventional HSS\u003c\/li\u003e\n  \u003cli\u003eTiN-T26 coating reduces friction and extends tool life in steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eBottoming chamfer (1.5 to 2P) enables threading close to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003eInternal coolant-through design supports high-speed and high-volume tapping\u003c\/li\u003e\n  \u003cli\u003eH5 thread limit with 2BX class of fit for precise thread geometry control\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for threading steel and stainless steel workpieces (ISO material application codes P and M) in blind hole applications requiring a 5\/16-18 UNC internal thread.

Ensure the workpiece is securely fixtured and the spindle is fully stopped before tap changes. Use the recommended cutting fluid or coolant for the workpiece material; the coolant-through feature requires an adequate supply at the required pressure. Verify tap alignment with the pre-drilled pilot hole before engaging to prevent tap breakage or thread distortion.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 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\u003eThread Limit\u003c\/strong\u003e: H5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 1.5 to 2P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.543 inches (90.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.551 inches (14.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 1.378 inches (35.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.318 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.238 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Powdered Metal High-Speed Steel (HSS-E-PM)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN-T26\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steel, Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: BU446A00\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.064 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: EMUGE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BU446A00.5010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EMUGE","offers":[{"title":"Default Title","offer_id":51972848550194,"sku":"BU446A00.5010","price":139.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fc7b027075cca2f2b6c20d65fbe20431.jpg?v=1789970927","url":"https:\/\/voomisupply.com\/products\/emuge-bu446a00-5010-thread-forming-tap-5-16-18-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
