The tap delivers precision-cut threads that are accurately formed for consistent, repeatable threading results. The tool is heat treated and tempered to file-hard hardness, extending service life and maintaining thread accuracy across repeated use. Designed for hand cutting applications, this combo set gives trades workers and machinists the matched tap and drill bit needed to complete a threaded hole from start to finish in one package.\u003c\/p\u003e\n\u003cp\u003eThis combo set is suited for hand tapping operations in metal fabrication, mechanical maintenance, and light industrial repair work. The 1\/4-28 National Fine thread specification is commonly used in applications requiring finer thread engagement and greater thread strength compared to coarse thread equivalents. The included number drill bit is sized to produce the correct pilot hole for the 1\/4-28 tap, eliminating the guesswork of bit selection. Suitable for use by HVAC technicians, plumbers, electricians, and general maintenance professionals when field threading is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-28 National Fine fractional tap for precise thread cutting\u003c\/li\u003e\n  \u003cli\u003eMatched number drill bit included for correct pilot hole sizing\u003c\/li\u003e\n  \u003cli\u003eHeat treated and tempered to file-hard finish for extended tool life\u003c\/li\u003e\n  \u003cli\u003ePrecision-formed threads for consistent, repeatable results\u003c\/li\u003e\n  \u003cli\u003eDesigned for hand cutting applications\u003c\/li\u003e\n  \u003cli\u003eSold as a 2-unit pack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for hand tapping applications requiring 1\/4-28 National Fine thread specification in metal and similar materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap set is intended for hand cutting use only. Secure the workpiece firmly before beginning and apply cutting fluid appropriate for the material being threaded to reduce friction and improve thread quality. Reverse the tap periodically during cutting to break chips and prevent binding.
