It features a modified bottoming chamfer that allows threading close to the bottom of blind holes, making it well suited for tight-tolerance production work. Built from powdered metal and finished with a steam oxide coating, this tap offers improved lubricity and wear resistance compared to standard high-speed steel tools. With 3 right-hand spiral flutes at a 15-degree helix angle, it efficiently evacuates chips upward out of the hole during the tapping cycle. Overall length is 2.375 inches. This tap is sold individually.\u003c\/p\u003e\u003cp\u003eThis tap is used in shop and field applications where 10-24 UNC threads are required in difficult-to-machine materials. Its material application range includes alloy steel, stainless steel, hardened steel, titanium, and high-nickel alloys, making it a practical choice for aerospace, automotive, and general precision machining environments. The modified bottoming chamfer is particularly useful in production setups where through-hole tapping is not possible and full thread engagement near the bottom of a blind hole is required. It is sized for use in CNC machining centers, drill presses, and tapping arms.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eModified bottoming chamfer for threading close to the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003eSpiral flute design at 15-degree helix angle promotes upward chip evacuation in blind hole applications\u003c\/li\u003e\n\u003cli\u003ePowdered metal construction provides greater wear resistance than standard HSS\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating improves lubricity and reduces galling in ferrous and high-nickel materials\u003c\/li\u003e\n\u003cli\u003eH5 thread limit designation for controlled oversize tolerance in close-fit thread applications\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, right-hand flute direction — standard orientation for conventional tapping setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting 10-24 UNC internal threads in alloy steel, stainless steel, hardened steel, titanium, and high-nickel alloy workpieces.

Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill diameter for 10-24 UNC threads before beginning. Apply appropriate cutting fluid for the workpiece material, particularly when tapping stainless steel, titanium, or high-nickel alloys. Do not exceed the tap's rated capacity by forcing feed rate or running the tap dry in hard materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 10-24\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: 24\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: 15 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\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\u003eShank Diameter\u003c\/strong\u003e: 0.194 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\u003eSquare Length\u003c\/strong\u003e: 0.25 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\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\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: 1703001\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51754939384114,"sku":"1703001","price":56.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a919ca79e01f031cd8f7f813828b12f_733b8f29-62ef-4892-af55-289a64360e22.jpg?v=1788949976","url":"https:\/\/voomisupply.com\/products\/osg-1703001-spiral-flute-tap-10-24-unc-modified-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
