It features a plug chamfer profile with 3 flutes and is manufactured from powdered metal with a steam oxide coating. The H5 thread limit and 2B class of fit make it suited for standard production threading where dimensional control is critical. With an overall length of 2.5 inches and a thread length of 0.62 inches, this right-hand tap is a compact tool appropriate for CNC machining centers, drill presses, and hand tapping setups. Machinists, tool and die makers, and maintenance technicians are the primary users.\u003c\/p\u003e\u003cp\u003eThe 1700201 is intended for through-hole threading in tough materials. It is rated for use in hardened steel, stainless steel, high-nickel alloy, titanium, alloy steel, and die steel. The spiral point geometry pushes chips ahead of the cutting action, making it most effective in through-hole applications where chip evacuation is essential. It is a strong fit for production environments where these difficult alloys are common. Coolant-through is not supported on this tap.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread size 1\/4-20 UNC with right-hand thread direction\u003c\/li\u003e\n\u003cli\u003ePlug chamfer for gradual thread engagement on through-hole work\u003c\/li\u003e\n\u003cli\u003e3-flute spiral point geometry pushes chips forward for clean chip evacuation\u003c\/li\u003e\n\u003cli\u003ePowdered metal construction improves wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating reduces friction and provides light lubricity during cutting\u003c\/li\u003e\n\u003cli\u003eH5 thread limit and 2B class of fit for standard tolerance threading\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for threading hardened steel, stainless steel, high-nickel alloy, titanium, alloy steel, and die steel.

Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill size for 1\/4-20 UNC before threading. Apply appropriate cutting fluid for the workpiece material to extend tool life and maintain thread quality. Do not reverse the tap without breaking the chip, as chip packing can cause tap breakage in tough alloys.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20 UNC\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\u003eChamfer Type\u003c\/strong\u003e: Plug\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: H5\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\/Finish\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.62 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.255 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: 312\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.032 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: 1700201\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51729420517682,"sku":"1700201","price":56.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7bf838a7b4dd29a520c4f6757557331e.jpg?v=1788704428","url":"https:\/\/voomisupply.com\/products\/osg-1700201-spiral-point-tap-1-4-20-unc-plug-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
