Taper taps are the standard starting tap for initiating threads in through holes or blind holes with adequate depth, cutting gradually over the first several threads to reduce torque and ease entry. This tap is designed for manual hand tapping operations using a tap wrench or T-handle, making it a go-to tool for machinists, pipefitters, maintenance technicians, and general metalworkers who need accurate, clean internal threads in ferrous and non-ferrous materials.\u003c\/p\u003e\u003cp\u003eThe 12-28 thread designation refers to a No. 12 major diameter with 28 threads per inch, a fine-pitch unified national thread form (UNF) commonly found in precision mechanical assemblies, electrical enclosures, and light machinery. This tap is suited for production shops, maintenance and repair operations (MRO), and field service work where a reliable, cost-effective import-grade tap meets the job requirements without the premium of domestic tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHSS construction provides adequate hardness and wear resistance for threading steel, aluminum, brass, and similar materials\u003c\/li\u003e\n\u003cli\u003eTaper chamfer (approximately 8-10 threads) eases starting and reduces torque demand during hand tapping\u003c\/li\u003e\n\u003cli\u003e12-28 UNF thread form suits precision fastener applications requiring fine pitch\u003c\/li\u003e\n\u003cli\u003eDesigned for hand tapping with standard tap wrenches or T-handles\u003c\/li\u003e\n\u003cli\u003eImport-grade pricing supports high-volume MRO and shop stock replenishment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or stock tap for 12-28 UNF hand tapping applications in general machining, maintenance, and repair operations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed machinist or qualified technician should select the correct tap drill size for the 12-28 thread form before beginning. Always apply appropriate cutting fluid to the tap and workpiece to reduce friction and extend tool life. Back off the tap periodically to break chips, especially in blind holes. Discard any tap that shows signs of chipping, cracking, or excessive wear to avoid broken-tap extraction issues.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 12-28\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Form\u003c\/strong\u003e: UNF (Unified National Fine)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Hand Taper Tap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.31 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: EAGLE CUTTING TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HT-1228-T-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233249755442,"sku":"HT-1228-T-I","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307622669.png?v=1780095373","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-ht-1228-t-i-hss-hand-taper-tap-12-28","provider":"Voomi Supply","version":"1.0","type":"link"}
