It features a 45-degree helix angle and three right-hand flutes that efficiently evacuate chips back out of the hole, making it well suited for bottoming applications where threads must be cut close to the bottom of a blind hole. The tap is manufactured from powdered metal and carries a TiCN (V) coating for improved wear resistance and lubricity. With an overall length of 2.48 inches and a thread length of 0.251 inches, it fits standard tapping tool holders used in manual and CNC tapping operations. Thread class of fit is 2B with an H3 thread limit.\u003c\/p\u003e\u003cp\u003eThis tap is intended for use in ferrous and non-ferrous metallic materials including alloy steel, low-carbon steel, medium-carbon steel, high-carbon steel, hardened steel, stainless steel, cast iron, and aluminum including cast aluminum. The bottoming chamfer style makes it the right choice when full thread depth is required at the base of a blind hole, a common requirement in fixture work, structural assemblies, and precision machined components across manufacturing and maintenance environments. It belongs to OSG Series 16505 and is used by machinists and tool-and-die professionals in both shop and field settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e45-degree right-hand spiral flutes evacuate chips efficiently in blind-hole bottoming applications\u003c\/li\u003e\n\u003cli\u003eTiCN (V) proprietary coating improves wear resistance and reduces friction across hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003ePowdered metal construction provides uniform grain structure and consistent cutting edge toughness\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer allows thread cutting to within one to two pitches of the hole bottom\u003c\/li\u003e\n\u003cli\u003eH3 thread limit and 2B class of fit ensure dimensional consistency for standard UNC fastener engagement\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, right-hand flute direction — compatible with standard tapping attachments and reversible tap drivers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for tapping 8-32 UNC threads in steel, stainless steel, cast iron, aluminum, and hardened materials per ISO material application codes P, M, K, N, and H.

Always ensure the workpiece is securely fixtured and the tap is properly aligned to the drilled hole before beginning the tapping cycle. Use an appropriate cutting fluid for the workpiece material to extend tool life and maintain thread quality. Do not attempt to reverse the tap without full disengagement from the thread form to avoid breakage, particularly in blind-hole applications.\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\u003eFlute Style\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Bottoming\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\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN (V Proprietary)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.48 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.251 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.168 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.826 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 21.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.131 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 32\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: 16505\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.016 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: 1650509708\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51734408397106,"sku":"1650509708","price":48.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2bc13f05c499606ff4e2a2009a7a9f1f.jpg?v=1788762930","url":"https:\/\/voomisupply.com\/products\/osg-1650509708-spiral-flute-tap-8-32-unc-bottoming-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
