Built from high-speed steel (HSS) with a bright, uncoated finish, this tap cuts a 2-1\/8-12 UNS right-hand thread and features a plug chamfer for gradual thread engagement at the start of the cut. With 6 flutes and an H6 thread limit tolerance, it delivers consistent thread geometry in a range of ferrous and non-ferrous materials. Overall length is 5.25 inches, and the tool weighs 3.8 pounds. Machinists and tool-and-die professionals rely on this tap for production and maintenance threading operations.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for manual and machine tapping applications requiring a 2-1\/8-12 UNS thread form. The plug chamfer style — typically 3 to 5 threads of taper — makes it a versatile choice for through-hole threading where the tap can pass fully through the workpiece. The H6 thread limit classifies the tap for general-purpose threading in steel, cast iron, aluminum, and similar materials. It is commonly used in heavy equipment maintenance, industrial fabrication, and toolroom environments where large-diameter threads must be cut accurately.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-1\/8-12 UNS thread size and pitch for large-diameter unified special threading\u003c\/li\u003e\n  \u003cli\u003e6 straight flutes for chip clearance in through-hole applications\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides gradual thread engagement and reduces starting torque\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction offers durability across common workpiece materials\u003c\/li\u003e\n  \u003cli\u003eH6 thread limit tolerance for general-purpose fit classification\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no coating buildup to affect thread tolerance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose straight flute tap for through-hole applications requiring a 2-1\/8-12 UNS right-hand thread.

Power down and lock out any machine tool before mounting or removing the tap from its holder. Use appropriate tapping fluid for the workpiece material to extend tool life and maintain thread quality. Do not exceed the tap's rated torque capacity for the material being threaded, and back off periodically to break chips when tapping by hand.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 2-1\/8-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\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: H6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.8 pounds\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\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: JY4879565\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700695728434,"sku":"JY4879565","price":566.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/79d9f7fd28530bfa8989dd2a13764e2f.jpg?v=1788393967","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4879565-straight-flute-tap-2-1-8-12-uns","provider":"Voomi Supply","version":"1.0","type":"link"}
