It features a modified bottoming chamfer, 3 right-hand spiral flutes with a 15-degree helix angle, and a steam oxide coating over a powdered metal substrate. The spiral flute design evacuates chips upward out of the hole, making it well suited for through- and blind-hole tapping where chip packing is a concern. Overall length is 2.375 inches, and the shank diameter is 0.194 inches. This tap is built for production and job-shop environments where thread quality and tool life in tough materials are priorities.\u003c\/p\u003e\n\u003cp\u003eThe OSG 1703301 is rated for use in alloy steel, stainless steel, hardened steel, titanium, and high-nickel alloys — material groups that demand a tap with good wear resistance and chip evacuation geometry. The modified bottoming chamfer allows threading closer to the bottom of a blind hole than a standard taper or plug tap. It is appropriate for aerospace, automotive, and general metalworking applications where 10-32 UNF threads are specified in tough or gummy materials. Installation is performed by machinists and tooling technicians using CNC machining centers, drill presses, or tapping arms with appropriate tapping fluid or coolant.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e10-32 UNF thread form with 32 threads per inch, right-hand thread direction\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer for threading close to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003e3-flute spiral design with 15-degree right-hand helix angle for upward chip evacuation\u003c\/li\u003e\n  \u003cli\u003ePowdered metal construction with steam oxide coating for wear resistance and lubricity\u003c\/li\u003e\n  \u003cli\u003eH5 thread limit designation for controlled oversize tolerance in harder materials\u003c\/li\u003e\n  \u003cli\u003eRated for alloy steel, stainless steel, hardened steel, titanium, and high-nickel alloys\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style threading tool for 10-32 UNF applications in metalworking operations involving alloy steel, stainless steel, hardened steel, titanium, and high-nickel alloy workpieces.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eTapping operations should be performed by qualified machinists following shop-specific feeds, speeds, and lubrication protocols for the workpiece material. Always secure the workpiece and ensure the spindle is properly aligned before engaging the tap to avoid breakage. Use appropriate tapping fluid or cutting oil — dry tapping in stainless or high-nickel alloys is not recommended. Inspect tap condition regularly, as worn taps in hard materials can seize or break without warning.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 10-32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 32\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\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5\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\u003eOverall Length\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.327 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.866 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.194 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.152 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\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: 0.025 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Stainless Steel, Hardened Steel, Titanium, High-Nickel Alloy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 1703301\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727538487602,"sku":"1703301","price":56.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/31ebfad6a9530f7d465ca10cd74d2d2d.jpg?v=1788679010","url":"https:\/\/voomisupply.com\/products\/osg-1703301-spiral-flute-tap-10-32-unf-modified-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
