Thread forming taps displace material rather than cutting it, producing stronger threads with no chip generation — a key advantage in blind hole applications. This tap is sized for M3x0.5 threads and carries a D5 thread limit. Overall length is 2.9375 inches with a thread length of 0.625 inches. The TiN coating extends tool life by reducing friction and improving wear resistance. Machinists and tool-and-die technicians use this tap in CNC machining centers, drill presses, and hand-tapping setups where clean, accurate metric internal threads are required.\u003c\/p\u003e\u003cp\u003eThis tap is suited for blind hole threading in ductile metals such as aluminum, mild steel, and similar machinable alloys. Its bottoming chamfer — 1 to 2 chamfered threads — allows threading to be taken very close to the bottom of a blind hole, maximizing thread engagement in shallow blind applications. It is appropriate for low-volume prototype work and production runs alike, with right-hand thread direction and a shank diameter of 0.141 inches to fit standard tap holders and chucks sized for the M3 range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming (chipless) design produces stronger threads and eliminates chip removal in blind holes\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer (1-2P) allows threading to within 1-2 pitches of hole bottom\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides toughness across a range of work materials\u003c\/li\u003e\n\u003cli\u003eTitanium nitride coating reduces friction, improves wear resistance, and extends tool life\u003c\/li\u003e\n\u003cli\u003eD5 thread limit for consistent thread fit in standard metric tolerance applications\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, M3x0.5 metric standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard supply tap for M3x0.5 metric blind hole threading operations in machining and fabrication environments.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by machinists and toolroom technicians using a standard tap wrench, tapping head, or CNC rigid tapping cycle. Ensure the tap holder matches the 0.141-inch shank diameter and square drive size. Apply appropriate cutting or forming fluid for the work material before tapping; forming taps require lubrication to prevent galling. Always verify hole diameter and depth per M3x0.5 thread forming tap drill charts before beginning the operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M3x0.5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 1-2P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: D5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.9375 inches (74.61 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches (3.58 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.110 inches (2.79 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K010451AS25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51755547001138,"sku":"K010451AS25","price":30.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e137a0898164e621dcbc56d79b9f7927.jpg?v=1788955955","url":"https:\/\/voomisupply.com\/products\/hertel-k010451as25-thread-forming-tap-m3x0-5-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
