Built from high-speed steel with a bright finish, it features a plug chamfer and 2 flutes with a right-hand thread direction. The H2 thread limit and Class 2B fit make it suitable for standard tolerance threading applications encountered in precision machining, maintenance, and fabrication environments. With an overall length of 1.688 inches and a thread length of 0.37 inches, this tap is well-suited for shallow-to-moderate depth tapping of small-diameter holes. It is installed by machinists, toolmakers, and mechanical technicians.\u003c\/p\u003e\u003cp\u003eThis tap is intended for use in both manual and machine tapping operations on #1-64 UNC threaded holes. It performs across a broad material range including aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel. The spiral point design pushes chips ahead of the cutting edges, making it especially effective in through-hole applications where chip evacuation is critical. It fits standard tap holders and drive handles sized for a 0.141-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-64 UNC thread size with right-hand thread direction and Class 2B fit\u003c\/li\u003e\n\u003cli\u003eH2 thread limit for standard tolerance control in production and repair work\u003c\/li\u003e\n\u003cli\u003ePlug chamfer eases tap entry and distributes cutting load across leading threads\u003c\/li\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward, reducing packing in through-hole tapping\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides wear resistance across ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eBright finish with no coolant-through requirement simplifies setup in dry or flood-cooled operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style threading tool for 1-64 UNC through-hole tapping applications across the stated material range; fits standard tap holders and drive tools accepting a 0.141-inch shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap should be installed by a qualified machinist or toolmaker using a properly sized tap wrench or machine tap holder. Secure the workpiece before operation and use cutting fluid appropriate for the work material to extend tool life and improve thread quality. Inspect the tap for wear or chipping before each use, and never force a tap that has stalled, as high-speed steel taps are brittle and susceptible to breakage under torsional overload.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-64\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.688 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.37 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Cast Iron, Hardened Steel, High-Carbon Steel, Low-Carbon Steel, Medium-Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.009 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1205200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51739782414642,"sku":"1205200","price":42.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/11454b747d94d6b61eb90f3c02abb9d1.jpg?v=1788818809","url":"https:\/\/voomisupply.com\/products\/osg-1205200-spiral-point-tap-1-64-unc-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
