It features a general purpose straight flute geometry with a plug chamfer that provides 1.5 inches of cutting depth, making it well suited for through-hole and moderately deep blind-hole tapping applications. Ground from cobalt steel, this tap handles higher heat and harder workpiece materials than standard high-speed steel taps. The bronze-oxide finish reduces friction and improves chip flow during the threading operation. It is sized for 1\/4-28 UNF threads and measures 2.5 inches in overall length.\u003c\/p\u003e\n\u003cp\u003eThis plug tap is used in machine shop, field fabrication, and maintenance applications where a clean, accurate 1\/4-28 UNF thread is required. The plug chamfer style — with its moderate lead-in taper — is the most common choice for general threading work, suitable for starting in a drilled hole and completing a thread with minimal hand pressure. Cobalt steel construction makes it a practical choice when threading stainless steel, cast iron, or other abrasion-resistant alloys that would wear out carbon-steel taps prematurely.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1500 Series plug tap with standard straight-flute geometry for general purpose threading\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer style with 1.5 inches of cutting depth for reliable thread starts in through and blind holes\u003c\/li\u003e\n  \u003cli\u003eCobalt steel construction for improved heat and wear resistance over standard HSS taps\u003c\/li\u003e\n  \u003cli\u003eBronze-oxide finish reduces friction and aids chip evacuation\u003c\/li\u003e\n  \u003cli\u003eSized for 1\/4-28 UNF threads — 2.5 inches overall length\u003c\/li\u003e\n  \u003cli\u003eSold individually (1 per pack)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general purpose replacement or new-installation tap for any application requiring a 1\/4-28 UNF internal thread in ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug taps are installed by machinists and maintenance technicians using a tap wrench, T-handle, or machine tapping head. Always use the correct tap drill size for 1\/4-28 UNF before tapping to avoid tap breakage. Apply a suitable cutting fluid appropriate to the workpiece material and back the tap out periodically to break chips and clear the flutes. Never force a tap — if resistance increases sharply, reverse and clear chips before continuing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1500\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: General Purpose Straight Flute Plug Tap\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Style\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Depth\u003c\/strong\u003e: 1.5 inches\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: Cobalt Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bronze Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 pounds\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: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1010017\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51343558312242,"sku":"1010017","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310538561.jpg?v=1782022693","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-1010017-plug-tap-1-4-28-2-5in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
