It threads 1\/4-20 UNC at a 2B class of fit using three flutes and a plug chamfer to drive chips forward ahead of the tap. The body is ground from 3% vanadium high-speed steel and finished with an oxide coating that provides mild lubricity and corrosion resistance. Overall length is 2.5 inches with a thread length of 19 millimeters. This tap is suited for machinists, maintenance technicians, and fabricators working in job shops, manufacturing facilities, and field repair environments.\u003c\/p\u003e\n\u003cp\u003eThe T1620402B is rated for use in stainless steel, making it appropriate for applications where conventional high-speed steel taps wear prematurely. The plug chamfer distributes cutting load across the first few threads, which helps reduce tap breakage on entry. Through-hole threading operations in ferrous and stainless workpieces are the primary application. This tap is a single-piece unit packaged individually and is sized for use in standard 1\/4-20 tapping operations on manual machines, CNC tapping heads, and hand tap wrenches.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point design pushes chips forward, keeping flutes clear during through-hole tapping\u003c\/li\u003e\n  \u003cli\u003e3% vanadium high-speed steel construction for increased wear resistance in stainless steel applications\u003c\/li\u003e\n  \u003cli\u003eOxide coating provides corrosion resistance and mild lubricity\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer distributes cutting load across several leading threads for stable entry\u003c\/li\u003e\n  \u003cli\u003e2B class of fit produces standard commercial thread tolerances\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction compatible with standard tapping equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard cutting tool for 1\/4-20 right-hand through-hole tapping operations.

Secure the workpiece fully before beginning the tapping operation to prevent movement. Use an appropriate cutting fluid or tapping compound, particularly when working in stainless steel, to extend tool life and improve thread finish. Do not reverse the tap under power without confirming the machine or tapping head supports reversing to avoid tap breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\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: Vanadium High-Speed Steel (3% Vanadium)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: 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: 19 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.48 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Stainless Steel\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: T1620402B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51755157979442,"sku":"T1620402B","price":34.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6c25fa0ec55f1e297092a0f7e2346833.jpg?v=1788951658","url":"https:\/\/voomisupply.com\/products\/accupro-t1620402b-spiral-point-tap-1-4-20-plug-2b","provider":"Voomi Supply","version":"1.0","type":"link"}
