Manufactured from high-speed steel (HSS) with a bright, uncoated finish, these taps deliver reliable cutting performance across a range of ferrous and non-ferrous materials. The 4-flute geometry provides strong chip evacuation and thread form accuracy. With an overall length of 4-11\/16 inches and a thread length of 2-7\/32 inches, the set is sized for standard production and maintenance threading operations. The H4 thread limit designation ensures consistent fit within standard UNC tolerance classes.\u003c\/p\u003e\u003cp\u003eThis tap set is suited for machine shops, maintenance facilities, and fabrication environments where 7\/8-9 UNC threaded holes are required. The right-hand thread direction makes it compatible with conventional CNC machining centers, drill presses, and manual tapping setups. A 3-piece set typically includes taper, plug, and bottoming taps, allowing machinists to start, advance, and finish threads in both through-holes and blind holes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread size: 7\/8-9 UNC, right-hand direction\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across common work materials\u003c\/li\u003e\n\u003cli\u003e4-flute design for improved chip clearance and thread accuracy\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for use with cutting fluids\u003c\/li\u003e\n\u003cli\u003eH4 thread limit for standard UNC fit tolerances\u003c\/li\u003e\n\u003cli\u003eOverall length of 4-11\/16 inches with 2-7\/32 inches of thread length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting 7\/8-9 UNC internal threads in standard tapping applications on manual and CNC equipment.

Always use an appropriate cutting fluid for the workpiece material to extend tap life and improve thread quality. Ensure the workpiece is securely fixtured before beginning the threading operation. Inspect the tap for wear or chipping before each use and replace if cutting edges are damaged.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-9 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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: H4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 2-7\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePieces in Set\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.7 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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MSC-04488128\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693447872818,"sku":"MSC-04488128","price":134.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4b1a26a7e76dc8c318b8decbb5b3f1f3.jpg?v=1788312491","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04488128-tap-set-7-8-9-unc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
