Built from powdered metal with a steam oxide coating, this tap handles alloy steel, stainless steel, hardened steel, titanium, and high-nickel alloys where standard high-speed steel tooling falls short. The modified bottoming chamfer allows threading close to the bottom of blind holes. With a 15-degree helix angle and right-hand spiral flute geometry, chips are pulled up and out of the hole during the tapping cycle, reducing the risk of chip packing and tap breakage in tough materials. Licensed machinists and toolroom technicians are the primary users of this tap.\u003c\/p\u003e\u003cp\u003eThis tap is suited for production and maintenance machining environments where 8-32 UNC threads are required in difficult-to-machine metals. The modified bottoming chamfer makes it a practical choice for blind-hole applications where full thread engagement near the hole bottom is required. The H3 thread limit supports standard 2B class of fit tolerances, making it appropriate for general-purpose fastener applications across aerospace, defense, medical device, and precision manufacturing work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePowdered metal construction with steam oxide coating for improved wear resistance and lubricity in tough materials\u003c\/li\u003e\n\u003cli\u003eModified bottoming chamfer for threading close to the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003eSpiral flute geometry with 15-degree helix angle evacuates chips away from the cutting zone\u003c\/li\u003e\n\u003cli\u003eH3 thread limit for 2B class of fit — meets standard tolerance requirements for general-purpose 8-32 UNC threads\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, right-hand flute direction — standard setup, no special toolholding required\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement — suitable for use with flood coolant or cutting oil applied externally\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use in alloy steel, stainless steel, hardened steel, titanium, and high-nickel alloy workpieces.

Ensure the workpiece is securely fixtured and the tap is properly aligned with the pilot hole before engagement. Use an appropriate cutting fluid or tapping compound rated for the workpiece material, particularly when working with stainless steel, titanium, or high-nickel alloys. Always confirm correct pilot hole diameter for 8-32 UNC before tapping to maintain the 2B class of fit tolerance.\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\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\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\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\u003eFlute Direction\u003c\/strong\u003e: Right Hand\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: 2.125 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\u003eSeries\u003c\/strong\u003e: 313\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 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\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: 1752301\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737596100914,"sku":"1752301","price":57.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fb3fc77ca1c974c4b85347a501088932.jpg?v=1788791093","url":"https:\/\/voomisupply.com\/products\/osg-1752301-spiral-flute-tap-8-32-unc-powdered-metal","provider":"Voomi Supply","version":"1.0","type":"link"}
