Built from HSS-E vanadium high speed steel with a 3% vanadium content, it delivers improved wear resistance over standard HSS taps. The bright, uncoated finish suits general-purpose tapping where lubrication is applied at the point of cut. With 2 flutes and a plug chamfer, this tap pushes chips forward ahead of the cutting edge, making it well suited for through-hole applications. The H2 thread limit and 2B\/3B class of fit meet standard fastener-tolerance requirements. Installed by machinists and maintenance trades in manual or CNC tapping operations.\u003c\/p\u003e\u003cp\u003eThis tap is intended for through-hole tapping in steel workpieces where a 4-40 thread is required. The spiral point geometry drives chips forward rather than backing them out, which keeps the flutes clear during continuous feed operations. At 1.87 inches overall length with an 11 mm thread length and a 3.58 mm shank diameter, it fits standard 4-40 tap holders and collets used in bench drill presses, tapping heads, and CNC machining centers. Right-hand thread direction matches standard 4-40 fastener orientation. No coolant-through capability; cutting fluid should be applied externally.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHSS-E 3% vanadium high speed steel for increased wear resistance over standard M2 HSS\u003c\/li\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward, optimized for through-hole tapping\u003c\/li\u003e\n\u003cli\u003ePlug chamfer provides a balance of cutting ease and thread engagement on entry\u003c\/li\u003e\n\u003cli\u003eH2 thread limit, 2B\/3B class of fit for standard inch-series fastener tolerances\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish for use with external cutting fluids across a range of steel grades\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, 2 flutes, suitable for manual and machine tapping operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting 4-40 UNC threads in steel applications.

Ensure the tap drill hole is properly sized for a 4-40 thread prior to tapping. Apply a suitable cutting fluid externally before and during the tapping operation; no coolant-through feature is present. Secure the workpiece fully before engaging the tap to prevent thread misalignment or tap breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Style\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\/3B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\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: HSS-E Vanadium (3% Vanadium)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.87 inches (47.6 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 11 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.58 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.28 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: T2640162\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51746680144178,"sku":"T2640162","price":32.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b1ff4ffa8867ee1d061dcd5fbcf8c33.jpg?v=1788872600","url":"https:\/\/voomisupply.com\/products\/accupro-t2640162-spiral-point-tap-4-40-plug-hss-e","provider":"Voomi Supply","version":"1.0","type":"link"}
