Manufactured from high speed steel (HSS) with a bright, uncoated finish, this plug-chamfer tap drives chips forward ahead of the cutting zone, keeping flutes clear and reducing the risk of thread damage during tapping operations. It carries an H3 thread limit and is rated for 2B and 3B class of fit, covering both general-purpose and closer-tolerance threading work. With 2 flutes and a 15\/16-inch thread length, it suits production and maintenance tapping in a range of materials.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for right-hand threading in through-holes where chip evacuation is the priority. It is commonly used in machining, fabrication, and maintenance-repair-operations (MRO) environments where 12-28 UNF fastener threads are required. The plug chamfer provides a progressive entry angle suitable for most through-hole work on the bench or in a drill press or CNC tapping setup. Machinists, tool-and-die technicians, and maintenance mechanics are the typical users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e12-28 UNF thread form for fine-pitch through-hole tapping\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer for progressive thread engagement and easy starting\u003c\/li\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward, away from the cutting edges\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit for 2B and 3B class of fit tolerances\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for general-purpose tapping performance\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — suitable for use with a wide range of cutting fluids\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard shop tap for any application requiring a 12-28 UNF, 2-flute, plug-chamfer spiral point tap with an H3 thread limit and 2B\/3B class of fit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the workpiece fully before tapping to prevent movement. Use an appropriate cutting fluid or tapping compound for the material being threaded. Align the tap perpendicular to the workpiece surface to maintain thread accuracy. Replace the tap if it shows signs of dulling, chipping, or excessive torque during cutting to avoid thread damage or tap breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 12-28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 15\/16 inches\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: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\/3B\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\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: 0.06 pounds\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: MSC-04519286\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698857279794,"sku":"MSC-04519286","price":15.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/623c14a1e0f12ea53ecbfdc53158c0b1.jpg?v=1788368962","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04519286-spiral-point-tap-12-28-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
