The bottom tap geometry features minimal chamfer on the leading threads, allowing the tap to cut threads as close to the base of the hole as possible. At 0.31 pounds, it is a lightweight, single-piece tool suited for bench work, maintenance threading, and production thread chasing by hand. Machinists, pipefitters, and maintenance technicians reach for this tap when a plug or taper tap cannot finish the last few threads in a stopped hole.\u003c\/p\u003e\n\u003cp\u003eThis tap is used wherever a 1\/4-20 unified coarse (UNC) internal thread must be cut flush to the bottom of a blind bore. Typical applications include threading holes in steel brackets, aluminum fixtures, and general fabrication work in mechanical, HVAC, plumbing, and electrical trade environments. It is operated by hand with a standard tap wrench and is well suited for repair threading, field service, and light production use where machine tapping is not practical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottom tap profile cuts threads to the base of blind holes where plug and taper taps cannot reach\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC thread form for one of the most common fastener sizes in trade and industrial applications\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction provides wear resistance across steel, aluminum, and similar materials\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.31 pounds for easy single-hand operation with a tap wrench\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 1 — available as a single-piece purchase for service and repair use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 UNC hand bottom tap compatible with any tap wrench sized to accept its shank.

Always start with a properly sized and drilled tap drill hole, using cutting oil or thread-cutting fluid to reduce friction and extend tap life. Back the tap out periodically to clear chips, especially in blind holes. Follow applicable shop safety practices and wear eye protection during all tapping operations.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Hand Bottom Tap\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.31 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: EAGLE CUTTING TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HT-2500-20-B-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233996341554,"sku":"HT-2500-20-B-I","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307622844.png?v=1780114415","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-ht-2500-20-b-i-1-4-20-hss-bottom-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
