Built from powdered metal with a steam oxide coating, this tap runs a right-hand, 3-flute spiral configuration with a 10-degree helix angle. The modified bottoming chamfer lets it thread close to the bottom of a blind hole. At 3.156 inches overall length with a 0.685-inch thread length, it fits standard tap holders used in CNC and manual machine shop applications. The H5 thread limit provides a tighter tolerance fit suited to precision assemblies. Licensed machinists and tool-and-die tradespeople are the primary users.\u003c\/p\u003e\u003cp\u003eThis tap is rated for stainless steel, hardened steel, titanium, and high-nickel alloys — materials that demand a tough substrate and a coating that reduces galling and built-up edge. The spiral flute design pulls chips up and out of the hole, making it well-suited for blind-hole tapping in interrupted or tough-grain materials. It is commonly used in aerospace, defense, medical device, and industrial equipment manufacturing where 6-32 UNC fasteners appear in tight-tolerance assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpiral flute geometry with 10-degree helix angle evacuates chips from blind holes\u003c\/li\u003e\n\u003cli\u003eModified bottoming chamfer threads close to hole bottom\u003c\/li\u003e\n\u003cli\u003ePowdered metal construction handles stainless steel, titanium, hardened steel, and high-nickel alloys\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating reduces friction and helps resist galling in difficult materials\u003c\/li\u003e\n\u003cli\u003eH5 thread limit for tight-tolerance 6-32 UNC thread production\u003c\/li\u003e\n\u003cli\u003eRight-hand thread and right-hand flute direction — standard orientation for most CNC and manual setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for tapping 6-32 UNC threads in stainless steel, hardened steel, titanium, and high-nickel alloys.

Always secure the workpiece and verify spindle alignment before tapping. Use cutting fluid or tapping compound appropriate for the workpiece material — particularly important with stainless steel and titanium to prevent work hardening and tap breakage. Inspect the tap for chipping or wear before each use; a damaged tap in hard material will break and may require EDM extraction.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 6-32\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: 10 degrees\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\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: 3.156 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.685 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1.713 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.323 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.11 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Stainless Steel, Hardened Steel, Titanium, High-Nickel Alloy\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: 313NI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 1709201\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728998007090,"sku":"1709201","price":69.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6ba53058cbced193c44428f462b90601_921c454c-2ce6-4c63-befe-5753a0f37ba5.jpg?v=1788698640","url":"https:\/\/voomisupply.com\/products\/osg-1709201-spiral-flute-tap-6-32-unc-modified-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
