The diagonal cutters are used for trimming wires to make them look more presentable after a repair has been made. Needle nose pliers are mainly used for cutting off old portions of a copper wire or wires depending on what is being worked on. The wire stripper is needed because many technicians usually have to create a new connection and in order to do this they need to be able to remove the insulation from the damaged area so a new connection can be made. A slotted or flathead screwdriver is used for loosening and tightening screws mainly to either remove or install a new circuit board.
The #1 Phillips is used for screws that have a crossroad appearance to them.. The 1/8 slotted screwdriver is used for smaller screws. The #0 Phillips is similar to the #1, however it has a little tip on the end of it to accommodate a different style screw. The desoldering pump is used for remove old solder or can be used to clean up a freshly made contact point. The soldering iron stand is used so the technician can place the iron on the stand instead of setting it down on a surface and possibly causing a fire from the heat generated by the tip.
The solder tube comes in handy because it would really be a misfortune to be working on a repair and you come to find out you dont have any solder to make the repair. Finally, the nut driver set is a great asset to have because many electronics have nuts that need removed or installed back on the product after a repair is complete. All in all, this is the type of tool kit, I would recommend for technicians to use when working on the job.
