Built from high-speed steel (HSS) with a fast flute style and a 52-degree helix angle, this tap pulls chips up and out of the hole rather than pushing them forward. It cuts a 10-24 UNC right-hand thread to a Class 2B\/3B fit tolerance at H3 limit. The plug chamfer provides a gradual lead-in suited for general-purpose tapping in a range of materials. Overall length is 2.375 inches, and the tool weighs 0.24 pounds. Machinists, toolmakers, and maintenance technicians rely on this geometry for clean, consistent threads in production and repair work.\u003c\/p\u003e\u003cp\u003eThis tap is applied in situations where a 10-24 UNC thread is required in through-holes or moderately deep blind holes. The spiral flute design and fast helix angle make it particularly effective in materials that produce stringy chips, such as aluminum, mild steel, and stainless steel, where a straight flute tap would pack chips into the flute. It is suited for use in CNC machining centers, drill presses, and hand tapping operations. The 3-flute configuration balances chip volume and tool strength at this thread size. The H3 thread limit accommodates standard 2B and 3B class-of-fit requirements found in most general mechanical assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e52-degree helix angle with fast flute style for efficient chip extraction in through-hole and blind-hole applications\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides wear resistance and performance across a broad range of work materials\u003c\/li\u003e\n\u003cli\u003ePlug chamfer lead-in (3-5 threads) for general-purpose tapping where the tap can be started from a chamfered or drilled entry\u003c\/li\u003e\n\u003cli\u003eH3 thread limit for Class 2B\/3B fit  -  compatible with standard mechanical assembly tolerances\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, right-hand flute  -  standard orientation for conventional tapping spindles\u003c\/li\u003e\n\u003cli\u003eNo coolant-through feature; suitable for flood coolant or manual lubrication\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct production tap for any application requiring a 10-24 UNC internal thread with a Class 2B\/3B fit at H3 tolerance limit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSecure the tap in an appropriate tap holder or floating tap collet to prevent breakage from misalignment. Always use a cutting fluid or tapping compound appropriate to the work material before starting the tap. Ensure the pilot hole is drilled to the correct tap drill diameter for a 10-24 UNC thread per standard machinists references. Back the tap out periodically to clear chips when tapping by hand, and never force a tap that has stopped rotating freely.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 10-24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Fast\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 52 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.24 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K008251AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51740773876018,"sku":"K008251AS","price":32.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a2ceb4eefbb4bb1506af7a02da994838.jpg?v=1788827361","url":"https:\/\/voomisupply.com\/products\/hertel-k008251as-spiral-flute-tap-10-24-unc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
