Built from 3% Vanadium High Speed Steel (HSS) with an oxide finish, this plug chamfer tap pushes chips forward ahead of the cut, making it well suited for through-hole tapping where chip evacuation is critical. The tap features a 2B Class of Fit, three flutes, and right-hand thread direction. Overall length is 3.375 inches with a thread length of 29 millimeters and a shank diameter of 9.32 millimeters. It is sized and specified for use in production and maintenance environments where consistent thread quality in tough materials is required.\u003c\/p\u003e\u003cp\u003eThis tap is rated for use in stainless steel, which demands a high-performance HSS grade to handle work hardening and cutting heat. The spiral point geometry drives chips ahead of the tap rather than packing them in the flutes, reducing the risk of tap breakage in deeper through-holes. It is appropriate for use in machine tapping operations on CNC machining centers, drill presses, and tapping heads, as well as hand tapping in field maintenance and repair scenarios. The oxide finish provides a degree of lubricity and corrosion resistance to extend tool life during repeated use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward, ideal for through-hole tapping\u003c\/li\u003e\n\u003cli\u003e3% Vanadium HSS construction for improved wear resistance in stainless steel and other tough alloys\u003c\/li\u003e\n\u003cli\u003ePlug chamfer (3-5 thread lead) for general-purpose machine and hand tapping\u003c\/li\u003e\n\u003cli\u003e2B Class of Fit for standard tolerance internal threads\u003c\/li\u003e\n\u003cli\u003eOxide finish for added lubricity and surface protection\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, 3 flutes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/2-13 UNC spiral point plug tap suitable for through-hole tapping in stainless steel and compatible materials where a 2B Class of Fit is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap should be installed in a properly sized and aligned tap holder or chuck to minimize runout and prevent breakage. Always use a cutting fluid or tapping compound rated for the workpiece material, particularly when tapping stainless steel. Ensure the through-hole is drilled to the correct tap drill diameter for a 1\/2-13 thread before tapping. Worn or dull taps should be replaced rather than forced, as stainless steel work hardens rapidly and increases the risk of tap failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 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 Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 3% Vanadium High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.375 inches (85.72 millimeters)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 29 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 9.32 millimeters\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: T1620562B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738065994034,"sku":"T1620562B","price":58.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/51fc6ce403efcc13e48ba4cee437b433.jpg?v=1788795931","url":"https:\/\/voomisupply.com\/products\/accupro-t1620562b-spiral-point-tap-1-2-13-3-flutes-plug","provider":"Voomi Supply","version":"1.0","type":"link"}
