Built from powdered metal (PMT15 grade) and finished with a TiCN coating, this tap delivers improved wear resistance and tool life over standard HSS taps. The 3-flute, plug chamfer geometry pushes chips forward ahead of the cutting zone, making it well suited for through-hole applications. With a 2B class of fit and H3 thread limit, it produces threads to standard tolerance for typical fastener and assembly applications. Overall length is 2.48 inches with a 0.374-inch thread length.\u003c\/p\u003e\u003cp\u003eThis tap is used in production and maintenance machining environments where 8-32 UNC threads are required in through-hole configurations. The TiCN coating and powdered metal substrate make it a strong choice for harder work materials including alloy steel, stainless steel, high-carbon steel, hardened steel, die steel, cast iron, and aluminum alloys. It is appropriate for use in manual tapping, CNC machining centers, and drill-tap operations where chip evacuation through the hole is achievable.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiCN coating improves hardness and lubricity for extended tool life in abrasive materials\u003c\/li\u003e\n\u003cli\u003ePowdered metal (PMT15) construction offers greater toughness and wear resistance than conventional HSS\u003c\/li\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward, optimized for through-hole tapping\u003c\/li\u003e\n\u003cli\u003e3-flute design balances chip room with core strength at the 8-32 thread size\u003c\/li\u003e\n\u003cli\u003eH3 thread limit and 2B class of fit meet standard tolerance requirements for general fastener applications\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction; no coolant-through feature required for most applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting 8-32 UNC through-hole threads in alloy steel, aluminum, cast aluminum, cast iron, hardened steel, high-carbon steel, low-carbon steel, medium-carbon steel, stainless steel, and die steel.

Ensure the workpiece is securely fixtured and the correct tap drill size for 8-32 UNC is used before tapping. Apply appropriate cutting fluid for the work material, particularly when tapping stainless or hardened steels. Do not reverse the tap under load without adequate lubrication, and avoid forcing the tap if resistance increases unexpectedly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32 UNC\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: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\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\u003eInterrupted Thread\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\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112806\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: 1651500808\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51739642462514,"sku":"1651500808","price":38.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd31e55832377234514e5664cd0515b5.jpg?v=1788817274","url":"https:\/\/voomisupply.com\/products\/osg-1651500808-spiral-point-tap-8-32-unc-ticn-coated","provider":"Voomi Supply","version":"1.0","type":"link"}
