Tap Set Appraisal

60-Piece SAE and Metric Combination Tap and Die Set

This item is a 60-piece combination tap and die set, designed for creating and repairing threads in both SAE (Society of Automotive Engineers) and Metric measurements. The set is housed in what appears to be a blue, rectangular metal case, characteristic of tool storage solutions. The case itself shows visible signs of age and use, including scuffs, scratches, and potentially some rust or corrosion, indicative of a working tool that has seen practical application. The primary visual is a silver-colored label or plate affixed to the top of the case, detailing the contents of the set in a clear, organized format. The label specifies a comprehensive collection of taps and dies, including various sizes of '#4-36', '#6-32', '#8-32', '#10-24', '#10-32', '#12-24', '1/4-20', '1/4-28', '5/16-18', '5/16-24', '3/8-16', '3/8-24', '7/16-14', '7/16-20', '1/2-13', '1/2-20', and '1/8-27NPT (Pipe)' for SAE threads. Metric sizes listed include 'M3 x 0.5', 'M3 x 0.6', 'M4 x 0.7', 'M4 x 0.75', 'M5 x 0.8', 'M5 x 0.9', 'M6 x 1.0', 'M7 x 1.0', 'M8 x 1.0', 'M8 x 1.25', 'M9 x 1.0', 'M9 x 1.25', 'M10 x 1.25', 'M10 x 1.5', 'M12 x 1.5', and 'M12 x 1.75'. Beyond the taps and dies, the set includes ancillary tools such as '1 each of OD Round Dies', '1 each of Plug Taps', '1 Die Stock', '1 Adjustable Tap Wrench', '1 T-Type Tap Wrench', '1 Screwdriver', and '2 Screw Pitch Gauges (Metric and SAE)'. The clarity and detail of the label suggest a functional and complete set, likely manufactured for general mechanical, automotive, or industrial use. The overall condition of the case points to an estimated age of several years, possibly from the mid to late 20th century or early 21st century, depending on the tool's brand and specific manufacturing era.
