The 45-degree right-hand helix moves chips up and out of the hole during tapping, reducing the risk of chip packing in blind or shallow holes. Made from vanadium high-speed steel with a steam oxide coating, it delivers good wear resistance and lubricity across moderate production runs. The modified bottoming chamfer allows threading closer to the bottom of a blind hole than a standard plug tap. Overall length is 2.125 inches. This tap is sized for use in a tap wrench, tapping head, or CNC machining center with appropriate feed control.\u003c\/p\u003e\n\u003cp\u003eThe OSG 1722301 is suited for threading operations in stainless steel, high-carbon steel, low-carbon steel, and medium-carbon steel workpieces. The 8-32 UNC thread form is common in instrument panels, electrical enclosures, small mechanical assemblies, and fastener applications across light manufacturing and maintenance trades. The modified bottoming chamfer makes it a practical choice where thread engagement must begin close to a blind hole floor. It is sold individually and is part of OSG Series 303.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e45-degree right-hand spiral flute promotes upward chip evacuation in blind holes\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer for threading near the base of blind holes\u003c\/li\u003e\n  \u003cli\u003eVanadium high-speed steel construction for wear resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eSteam oxide coating reduces friction and improves lubricity during cutting\u003c\/li\u003e\n  \u003cli\u003eH5 thread limit for controlled tolerance fit\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, 32 threads per inch, UNC standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in stainless steel, high-carbon steel, low-carbon steel, and medium-carbon steel.

Secure the workpiece before tapping and apply cutting fluid appropriate for the workpiece material, particularly when tapping stainless steel. Do not exceed the recommended feed rate for the thread size, and back the tap out periodically to clear chips when working in deeper blind holes. Inspect the tap for wear or chipping before each use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\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: 45 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\u003eThreads per Inch\u003c\/strong\u003e: 32\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: Vanadium High-Speed Steel\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: 2.125 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: 303\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.016 pounds\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: 1722301\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51744010830130,"sku":"1722301","price":47.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/123a5419d4d8a0a86cd8bd57a04a4324.jpg?v=1788852878","url":"https:\/\/voomisupply.com\/products\/osg-1722301-spiral-flute-tap-8-32-unc-vanadium-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
