Built from powdered metal (grade PMT15) and finished with a TiCN coating, this plug-chamfer tap is engineered for longer tool life and reduced friction compared to standard HSS taps. It runs right-hand, cuts a 3B class of fit, and holds an H2 thread limit for consistent tolerance control. The 3-flute spiral point pushes chips forward ahead of the cutting zone, making it well suited for through-hole applications where chip evacuation is critical.\u003c\/p\u003e\u003cp\u003eThis tap is intended for use in a wide range of ferrous and non-ferrous materials including low-carbon steel, medium-carbon steel, high-carbon steel, alloy steel, hardened steel, die steel, cast iron, stainless steel, aluminum, and cast aluminum. It is appropriate for CNC tapping centers, drill presses, and hand-tapping operations where 8-32 UNC internal threads are required. The plug chamfer (3-5 thread lead) makes it a standard choice for through-hole threading in production runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiCN coating reduces friction and extends tool life in abrasive and hard materials\u003c\/li\u003e\n\u003cli\u003ePowdered metal (PMT15) substrate provides superior wear resistance over standard M2 HSS\u003c\/li\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward  -  optimized for through-hole tapping\u003c\/li\u003e\n\u003cli\u003eH2 thread limit maintains tight tolerance control for 3B class of fit threads\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, plug chamfer  -  compatible with standard CNC and manual tapping setups\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement  -  compatible with flood, mist, or tap-magic lubrication\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for threading 8-32 UNC through holes in alloy steel, aluminum, cast aluminum, cast iron, hardened steel, high-carbon steel, low-carbon steel, medium-carbon steel, stainless steel, and die steel applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap should be installed by a machinist or tool-and-die professional familiar with threading operations and proper speeds and feeds for the workpiece material. Always ensure the spindle is stopped and the machine is powered down before changing tooling. Use appropriate tapping fluid or cutting oil matched to the workpiece material to prevent galling, especially in stainless steel and hardened steel. Follow the machine manufacturer and tap manufacturer guidelines for RPM and feed rate  -  do not force the tap if resistance increases unexpectedly, as breakage in a workpiece bore is difficult to recover.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Style\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Powdered Metal (PMT15)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.48 inches (63 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.374 inches (9.5 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.168 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 16515\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.017 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: 1651500908\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743481626930,"sku":"1651500908","price":41.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6b69df3e10bd5e6f7c6f9153b2b03201.jpg?v=1788847527","url":"https:\/\/voomisupply.com\/products\/osg-1651500908-spiral-point-tap-8-32-unc-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
