The bottom tap geometry features minimal lead threads, allowing the tap to reach full thread depth closer to the base of the hole than taper or plug taps. At 0.31 pounds, this is a lightweight hand tool suited for bench work and field threading by machinists, maintenance technicians, and trade professionals working with small-diameter fastener threads.\u003c\/p\u003e\u003cp\u003eThis tap is intended for use in applications requiring 3-56 UNC thread form in blind holes where thread engagement must extend as deep as possible. Typical use cases include instrument panels, electrical enclosures, small mechanical assemblies, and precision sheet metal work. It is operated by hand using a standard tap wrench and is appropriate for use in ferrous and non-ferrous materials at this thread size.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBottom tap style for threading to the base of blind holes\u003c\/li\u003e\n\u003cli\u003e3-56 thread size for small-diameter, fine-pitch fastener applications\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction for durability across a range of materials\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.31 pounds for easy hand operation\u003c\/li\u003e\n\u003cli\u003eMinimum order quantity of 1 for single-unit procurement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement or supplementary bottom tap for hand threading operations requiring 3-56 thread form; consult your tap wrench specifications to confirm shank compatibility before use.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by hand using a standard tap wrench — power driving is not recommended for taps at this thread size due to breakage risk. Ensure the workpiece is securely clamped before starting. Apply appropriate cutting fluid to extend tap life and reduce friction. Clear chips frequently during use, especially in blind holes, to prevent binding and tap breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3-56\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Hand Bottom\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\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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-356-B-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233291469106,"sku":"HT-356-B-I","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307622863.png?v=1780096449","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-ht-356-b-i-3-56-hss-hand-bottom-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
