It is manufactured from high-speed steel with an oxide coating for improved lubricity and wear resistance during cutting operations. The tap features three flutes with a right-hand helix angle of 45 degrees, a fast flute style, and cuts a right-hand thread to a 2B class of fit with an H3 thread limit. Overall length is 2.125 inches. It is installed by machinists and toolroom technicians in production and maintenance threading applications.\u003c\/p\u003e\u003cp\u003eThis tap is suited for threading blind holes where full thread depth is required close to the bottom of the bore. The bottoming chamfer, combined with the spiral flute geometry, efficiently evacuates chips up and out of the hole during cutting. It is commonly used in metalworking operations involving ferrous and non-ferrous materials where a standard 8-32 UNC thread form is specified. Typical applications include machine assembly, fixture fabrication, and repair work in job shop and production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBottoming chamfer allows threading to the full depth of a blind hole\u003c\/li\u003e\n\u003cli\u003e45-degree right-hand helix with fast flute style promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides durability across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eOxide coating reduces friction and improves tap life in general-purpose threading\u003c\/li\u003e\n\u003cli\u003eH3 thread limit and 2B class of fit meet standard tolerance requirements for 8-32 UNC threads\u003c\/li\u003e\n\u003cli\u003eThree-flute design balances cutting load and rigidity in smaller-diameter tapping\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 8-32 UNC bottoming tap suitable for use in any tapping setup, drill press, CNC machining center, or hand tapping application that accepts straight-shank taps of this diameter and thread specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by machinists using a tap wrench, tapping head, or machine spindle with appropriate torque control. Ensure the pilot hole is drilled to the correct tap drill size for 8-32 UNC before beginning the threading operation. Apply cutting fluid appropriate for the workpiece material to extend tap life and improve thread quality. Never reverse-cycle a bottoming tap without first backing off to break the chip, as this risks tap breakage in blind holes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32\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\u003c\/strong\u003e: Bottoming\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: 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: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.125 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: 0.16 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K033005AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51747535487282,"sku":"K033005AS","price":34.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/684451d4f10a166d2ea2a15e5ca7af26.jpg?v=1788882083","url":"https:\/\/voomisupply.com\/products\/hertel-k033005as-spiral-flute-tap-8-32-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
