Built from powdered metal and finished with a steam oxide coating, this tap handles stainless steel, hardened steel, titanium, and high-nickel alloys where standard HSS taps struggle. The modified bottoming chamfer allows threading close to the bottom of blind holes. With a 10-degree helix angle and three right-hand spiral flutes, the tool efficiently evacuates chips upward during cutting, reducing the risk of chip packing in confined bores. Overall length is 4.331 inches with a 0.685-inch thread length.\u003c\/p\u003e\u003cp\u003eThis tap is suited for production and maintenance machining environments where precision threaded 6-32 holes are required in tough alloys. Typical applications include aerospace components, medical hardware, and high-strength fastener installations where thread quality and tool life in hard materials are critical. It carries a 2B class of fit designation with an H3 thread limit, producing threads within standard tolerance for general mechanical assembly. The Series 313NI designation identifies it as part of OSG's line optimized for nickel-alloy and stainless applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eModified bottoming chamfer for threading near the base of blind holes\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating improves lubricity and reduces galling in stainless and nickel alloys\u003c\/li\u003e\n\u003cli\u003ePowdered metal construction provides higher wear resistance than standard HSS\u003c\/li\u003e\n\u003cli\u003e10-degree right-hand helix angle promotes upward chip evacuation in blind hole applications\u003c\/li\u003e\n\u003cli\u003eH3 thread limit and 2B class of fit for consistent, in-tolerance thread production\u003c\/li\u003e\n\u003cli\u003eNo coolant-through design — compatible with standard flood or manual lubrication\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting 6-32 UNC right-hand threads in stainless steel, hardened steel, titanium, and high-nickel alloys.

Ensure the workpiece is securely fixtured and the tap is properly aligned to the drilled hole before engagement. Use a cutting fluid or tapping compound rated for the specific workpiece material, particularly when working with stainless steel or nickel alloys, to extend tool life and prevent galling. Never force a tap that has stopped advancing — back off to clear chips before continuing.\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\u003eChamfer\u003c\/strong\u003e: Modified 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\u003eThreads per Inch\u003c\/strong\u003e: 32\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\u003eOverall Length\u003c\/strong\u003e: 4.331 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: 1.472 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.429 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\u003eCoolant Through\u003c\/strong\u003e: No\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: 0.011 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: 1709101\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737440026930,"sku":"1709101","price":69.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7fa88f2885228f8ef8492018c029ad6a.jpg?v=1788788577","url":"https:\/\/voomisupply.com\/products\/osg-1709101-spiral-flute-tap-6-32-unc-modified-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
