Part of the Protodyn S Plus series (AP2261705), it is manufactured from High-Speed Steel-E (cobalt-grade HSS) and finished with a Titanium Nitride (TiN) coating for extended tool life and reduced friction. The tap produces a 2B class of fit with a modified bottoming chamfer, making it well suited for threading close to the bottom of blind holes. Overall length is 2.125 inches with a thread length of 0.5906 inches (15.00 mm). Licensed machinists and tool-and-die tradespeople are the primary installers.\u003c\/p\u003e\u003cp\u003eThis tap is intended for use in precision metalworking environments where consistent 8-32 UNC thread forming is required. The modified bottoming chamfer, with 2-3 chamfered threads, allows threading to near-bottom depth in blind holes without a separate bottoming operation. Material application codes P, M, N, and S indicate suitability across carbon steels, stainless steels, non-ferrous metals, and heat-resistant alloys. The tap does not require coolant-through capability for standard applications but benefits from cutting oil or appropriate threading fluid to maintain surface finish and tool longevity.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8-32 UNC thread size with 2B class of fit for standard precision threading\u003c\/li\u003e\n\u003cli\u003eModified bottoming chamfer with 2-3 chamfered threads for near-bottom blind hole threading\u003c\/li\u003e\n\u003cli\u003eHigh-Speed Steel-E (cobalt) construction for improved heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends tool life in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e5 oil grooves and 3.5xD flute-by-diameter ratio for efficient chip and fluid management\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction; no coolant-through required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style thread forming tap for 8-32 UNC blind hole and through-hole threading applications across steel, stainless, non-ferrous, and heat-resistant alloy workpieces, per material application codes P, M, N, and S.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this tap should be performed by qualified machinists familiar with threading operations and applicable shop safety standards. Power down and secure all rotating equipment before changing or inspecting taps. Apply an appropriate threading fluid or cutting oil to the tap and workpiece before use to protect the coating and extend tool life. Inspect the tap for wear or chipping between uses; do not use a damaged tap, as it may produce out-of-tolerance threads or break in the workpiece.\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\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\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\u003eOverall Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.5906 inches (15.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1640 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.1310 inches\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\u003eOil Grooves\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3.5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading, Through-Hole Threading\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application Codes\u003c\/strong\u003e: P, M, N, S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: AP2261705\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrade Name\u003c\/strong\u003e: Protodyn S Plus\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WALTER-PROTOTYP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5934680\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":67910912344370,"sku":"5934680","price":105.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/53ff4f7b3b4381109cbc0e5873ff2013.jpg?v=1791201429","url":"https:\/\/voomisupply.com\/products\/walter-prototyp-5934680-thread-forming-tap-8-32-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
