Built from high-speed steel, it produces clean, accurate 1\/4-20 UNC right-hand threads across a 1-inch thread length. The plug chamfer  -  typically 3 to 5 threads  -  makes it suitable for through-hole tapping applications where the tap can pass fully through the material. With an overall length of 2.5 inches and 4 flutes, it is sized for use in hand tapping setups or machine tapping operations on drill presses, mills, and CNC machining centers. Machinists and metalworking tradespeople rely on this tap for production and maintenance threading work.\u003c\/p\u003e\u003cp\u003eThis tap is suited for tapping through holes in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel. Its straight flute design works best in shorter-chipping materials where chip clearance from the flutes is not a limiting factor. It is a common choice for general maintenance shops, machine shops, and field repair scenarios requiring standard UNC threaded fastener holes in 1\/4-20 applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 UNC thread form with right-hand thread direction\u003c\/li\u003e\n\u003cli\u003ePlug chamfer for through-hole tapping\u003c\/li\u003e\n\u003cli\u003e4 straight flutes for use in shorter-chipping materials\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across a range of metals\u003c\/li\u003e\n\u003cli\u003eH2 thread limit for close-tolerance thread production\u003c\/li\u003e\n\u003cli\u003eCoolant-through design not required  -  standard external coolant application\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard production tap for through-hole 1\/4-20 UNC threading operations in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel workpieces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by machinists and metalworking technicians using a tap wrench, tapping handle, or machine tap holder. Ensure the workpiece is securely clamped and the pilot hole diameter matches the recommended tap drill size for 1\/4-20 UNC threads before beginning. Apply a suitable cutting fluid or tapping compound for the specific workpiece material to extend tool life and improve thread quality. Do not exceed the recommended feed rate or force the tap if resistance increases unexpectedly, as this can cause breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20 UNC\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: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Cast Iron, Low-Carbon Steel, Medium-Carbon Steel, High-Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 101\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1110102\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743930057010,"sku":"1110102","price":25.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/af4a65e307fa8e6d42ffc2eb433685ee.jpg?v=1788851476","url":"https:\/\/voomisupply.com\/products\/osg-1110102-straight-flute-tap-1-4-20-unc-plug-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
