Everest NES thread repair tools offer an innovative, easy way to restore any damaged threads on site. They are part of every maintenance job to deal with damaged threads, which are usually not the maintenance project target but cannot be ignored or avoided and must be fixed in order to complete the job, which takes time, and time lost is production lost. The loss is not just wasted labour charges in idle time, but the damage to parts and system and many other related expenses that are not calculated. In order to reduce the "down time" of the production line one has to act fast and effectively to delete the factors that cause such time loss.

When it comes to threads, Everest NES is the ultimate answer for that, it is an universal tool that can fit into any diameter, eliminates the need of monitoring, which type of thread one is dealing with, as it automatically finds the right pitch and standard used. It is simple to use and the results are fast and effective.

The maintenance engineer can carry to the jobsite the small set with thread repair tools - like Set 1017 (4 tools). This will allow him to replace more than 600 taps and dies, or over 1000 taps and dies if in case he opts for Set 1025 (6 tools). Thread repair tools are designed for working in the toughest conditions, the tool produced to the highest quality, its cutting blades manufactured in the most modern way to assure the user a long time of usage.

Thread repair tools are available in 2 types: tools for fixing internal threads and tools for repairing external threads.

Internal Thread Repair

The internal thread repair tool uses single blade and can work in both directions. Once set in its place, the blade locates the right thread slot and follows it to improve its form as close as possible to its original shape. The advantages are:

• Working the thread from inside out eliminates the chances of "cross threading" the top of the thread (like what happened sometimes when using a tap), and
• While using the Yellow Nylon pads, soft materials like aluminium, magnesium or brass can be treated easily and safely with excellent results.

External Thread Repair

The external thread repair tool uses two blades that are floating just about enough to find the right measurement and pitch of the original thread given. Once in place, all that the "job" requires is to rotate the tool in the right given direction (marked with an arrow). This movement will fix the thread slot and recondition its form to the original shape.

Special accessory to fix keyways is available for NES 3. That accessory is among the best tools to fix large thread shafts that incorporate keyway slots, as it does it easily, smoothly with great results. The recommendations are very simple - after checking the available options for maintenance and repair of threads in industry, one has to be careful in selecting the right tools. Everest - NES repair tools are easy to use and cost-effective in terms of production expenses.
