It features three flutes with a plug chamfer, which provides a gradual cutting action suitable for through-hole applications. Manufactured from vanadium high-speed steel (HSS-E) and finished with a TiCN (titanium carbonitride) coating, this tap delivers improved wear resistance and heat tolerance compared to uncoated HSS taps. The H5 thread limit and 2B class of fit make it appropriate for standard fastener thread tolerances in production and maintenance machining.\u003c\/p\u003e\u003cp\u003eThis tap is suited for through-hole tapping operations in materials including low-carbon steel, medium-carbon steel, hardened steel, and stainless steel. The spiral point design pushes chips forward ahead of the tap, making it effective in CNC machining centers, drill presses, and tapping machines where a continuous chip flow is preferred. It is a common choice for job shops, production floors, and maintenance machinists working with 1\/4-20 fastener threads in steel components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 UNC thread form, H5 thread limit, 2B class of fit for standard tolerance applications\u003c\/li\u003e\n\u003cli\u003eThree-flute spiral point (gun tap) geometry pushes chips forward for use in through-hole applications\u003c\/li\u003e\n\u003cli\u003eVanadium high-speed steel (HSS-E) construction provides toughness in ferrous materials\u003c\/li\u003e\n\u003cli\u003eTiCN coating increases surface hardness and reduces friction for extended tool life\u003c\/li\u003e\n\u003cli\u003ePlug chamfer with right-hand thread direction for conventional tapping setups\u003c\/li\u003e\n\u003cli\u003eNo coolant-through design; suitable for flood or manual lubrication\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use in hardened steel, low-carbon steel, medium-carbon steel, and stainless steel.

Secure the workpiece and ensure the tap is properly aligned before engagement to prevent breakage. Use an appropriate cutting fluid or tapping oil for the material being machined. Inspect the tap for wear or chip buildup between uses, and never force a tap that has stalled in the hole.\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\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\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\u003eMaterial\u003c\/strong\u003e: Vanadium High-Speed Steel (HSS-E)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\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: 300\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.031 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: 1737408\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728711450930,"sku":"1737408","price":40.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/30603497354706462f1b4fb19c1251bd.jpg?v=1788695354","url":"https:\/\/voomisupply.com\/products\/osg-1737408-spiral-point-tap-1-4-20-unc-ticn-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
