It features a 2-flute, right-hand spiral design with a 15-degree helix angle that evacuates chips upward out of the hole — a critical advantage when tapping blind holes. The modified bottoming chamfer allows threading close to the bottom of a hole while maintaining controlled chip flow. Manufactured from powdered metal and finished with a steam oxide coating, this tap is built for resistance to wear and heat in production tapping environments. Overall length is 2.125 inches.\u003c\/p\u003e\u003cp\u003eThis tap is suited for threading 8-32 UNC holes in alloy steel, stainless steel, hardened steel, titanium, and high-nickel alloys. The modified bottoming chamfer makes it a strong choice in applications where full thread depth near the bottom of a blind hole is required. It is appropriate for CNC machining centers, manual tapping, or any fixture-guided tapping operation where chip evacuation is a priority. The H5 thread limit provides a controlled oversize condition for accurate thread fit in tight-tolerance assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8-32 UNC thread form, right-hand thread direction\u003c\/li\u003e\n\u003cli\u003e2-flute spiral design with 15-degree helix angle for upward chip evacuation\u003c\/li\u003e\n\u003cli\u003eModified bottoming chamfer for threading close to hole bottom\u003c\/li\u003e\n\u003cli\u003ePowdered metal construction with steam oxide coating for wear and heat resistance\u003c\/li\u003e\n\u003cli\u003eH5 thread limit, oversize — suitable for precision thread-fit control\u003c\/li\u003e\n\u003cli\u003eNo coolant-through — compatible with external cutting fluid application\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-use tap for 8-32 UNC threaded holes in alloy steel, stainless steel, hardened steel, titanium, and high-nickel alloy workpieces.

Ensure the workpiece and tap are securely fixtured before beginning the thread cycle. Apply an appropriate cutting fluid for the workpiece material to reduce friction and extend tap life. Inspect the tap for wear or chipping before each use — a damaged tap can seize in the hole and cause workpiece damage.\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: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\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: Modified Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.252 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: 0.752 inches\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOversize\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 313\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 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: 1754801\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737736085810,"sku":"1754801","price":55.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a919ca79e01f031cd8f7f813828b12f_72487c1e-b042-4ac3-a9a9-f541af7f7b1b.jpg?v=1788792969","url":"https:\/\/voomisupply.com\/products\/osg-1754801-spiral-flute-tap-8-32-unc-modified-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
