Built from powdered metal with a steam oxide coating, it handles alloy steel, stainless steel, hardened steel, titanium, and high-nickel alloys where standard high-speed steel taps fall short. The modified bottoming chamfer allows threading close to the bottom of blind holes, making it well suited for tight-tolerance fastener applications. With a 15-degree helix angle and 2 right-hand flutes, it evacuates chips efficiently in short-chipping and stringy materials. Overall length is 2 inches, and it carries a 3B class of fit for standard commercial thread tolerance. Installed by machinists and tool-and-die professionals in both production and maintenance environments.\u003c\/p\u003e\u003cp\u003eThis tap fits production machining, CNC tapping, and manual tapping operations where a fine 6-32 UNC thread is required in tough or abrasion-resistant base materials. The modified bottoming chamfer makes it particularly useful in blind-hole applications where full thread depth close to the hole bottom is needed. The steam oxide finish reduces friction and provides a degree of lubricity that extends tool life when cutting stainless steel, titanium, and high-nickel alloys. It is sold individually and intended for use with appropriate tapping lubricant or cutting fluid matched to the workpiece material.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e6-32 UNC thread form with 32 threads per inch and 3B class of fit for standard commercial tolerance\u003c\/li\u003e\n\u003cli\u003eModified bottoming chamfer for threading close to the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003ePowdered metal construction provides hardness and wear resistance in difficult-to-machine alloys\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating reduces friction and extends tool life in stainless steel, titanium, and high-nickel alloys\u003c\/li\u003e\n\u003cli\u003e15-degree right-hand spiral flute promotes upward chip evacuation in short and stringy chip materials\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction; H2 thread limit for consistent fit across production runs\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.

Always use a cutting fluid or tapping compound appropriate for the workpiece material, particularly when cutting stainless steel or titanium. Ensure the tap is aligned perpendicular to the workpiece surface before engaging threads to prevent tap breakage. Do not back-drive a tap under power without confirming the machine supports synchronized retraction.\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\u003eThreads per Inch\u003c\/strong\u003e: 32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\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\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\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\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.248 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.685 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\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 313\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: 1754301\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51755819335986,"sku":"1754301","price":50.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a919ca79e01f031cd8f7f813828b12f_4eaf1c2e-bc33-4a92-ba2d-167810b80b27.jpg?v=1788960079","url":"https:\/\/voomisupply.com\/products\/osg-1754301-spiral-flute-tap-6-32-unc-modified-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
