•Easy to use with a relatively short learning curve, even for users not accustomed to thread repair tools.
•Works great for chasing threads and removing powder coating, ensuring a tight seal and clean ground.

•Considered an essential tool for hydraulic cylinder maintenance and similar repair tasks.
•Helps save parts that might otherwise need full replacement, offering economical repair options.

Cons

•Slight design issue with the external thread repair tool where two teeth protrude about 1/8 inch, which can cause the handle to hit obstacles, limiting its clearance in tight spaces.
•May not be able to repair all thread types or sizes due to handle clearance and tool design constraints.
•The tool is somewhat unusual, so users unfamiliar with this type of repair tool might find it a bit unfamiliar initially.

Bottom Line

The Nes Universal External/Internal Thread Repair Kit NES1A, 4-piece set is a high-quality, reliable, and innovative solution for repairing both internal and external threads across models 21, 22, and 23. It shines especially in automotive and hydraulic cylinder repairs by saving time, effort, and replacement parts. However, if you frequently work in very tight or complex spaces, the design limitations around the external thread tool's handle clearance might hinder usability. Overall, this is a smart purchase for anyone needing a versatile thread repair kit that performs consistently well without breaking the bank. For those needing a simpler or more compact option, exploring other kits might be advisable.
