Built from high-carbon steel with a black oxide finish, it offers good wear resistance and corrosion protection for general-purpose tapping applications. The plug chamfer style features a gradual lead-in that distributes cutting load across several threads, making it well-suited for production work and repair threading. Machinists, maintenance technicians, and trade professionals install this tap by hand or with a tapping fixture to produce clean, accurate 2B-class threads in a range of workpiece materials.\u003c\/p\u003e\u003cp\u003eThis tap is used in light manufacturing, MRO maintenance, and field repair applications where 8-32 machine screw threads are required. Its 3-flute straight configuration performs well in shorter chipping materials such as aluminum, mild steel, and plastic. The compact 2.25-inch overall length fits standard tap wrenches and T-handle drivers used in both shop and field settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eStraight flute design optimized for through-hole and short blind-hole tapping in chipping materials\u003c\/li\u003e\n\u003cli\u003ePlug chamfer distributes cutting forces gradually across the lead threads for controlled thread engagement\u003c\/li\u003e\n\u003cli\u003eHigh-carbon steel construction provides durability for general-purpose threading tasks\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish reduces friction and provides light corrosion resistance during use\u003c\/li\u003e\n\u003cli\u003e3-flute geometry balances chip evacuation and thread wall support\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction compatible with standard tap wrenches and drill press tapping attachments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement straight flute tap for applications requiring 8-32 unified coarse internal threads in ferrous and non-ferrous workpieces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed machinist or experienced maintenance technician should install this tap using a properly aligned tap wrench or tapping fixture to prevent breakage. Secure the workpiece firmly and apply cutting fluid appropriate for the workpiece material before starting. Back the tap out periodically to break and clear chips, especially in deeper holes. Never force a tap against resistance — back off and clear chips before continuing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Straight Flute\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 0.7940 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.7500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOversize\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: MILWAUKEE TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 49-57-5121\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILWAUKEE","offers":[{"title":"Default Title","offer_id":51709116121394,"sku":"49-57-5121","price":15.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5b0ac06adefa4caa9921b429e1b4ebc4.jpg?v=1788451512","url":"https:\/\/voomisupply.com\/products\/milwaukee-tool-49-57-5121-straight-flute-tap-8-32","provider":"Voomi Supply","version":"1.0","type":"link"}
