Everyone requires a well-stocked toolbox. However, there are several items that service technicians simply cannot go without. If you are new to the profession, the list below will be highly helpful, or if you have been in the game for a while, you may find some additional tools to add to your toolkit.


Technician's Toolbox - The Complete Tools for Technician List


1) Cordless Drill

Have you ever seen a technician working without his or her drill? These power tools are essential for everything from doing the obvious i.e. drilling holes to doing other operations such as inserting screws through studs.

A cordless drill is useful over a traditional drill since you don't have to carry extension cables around or look for outlets. However, before choosing a cordless drill, make sure you check the voltage to make sure it can perform fieldwork. Anything under 18 volts is typically used for home repairs and small projects. A drill with a voltage of 20 volts or greater should be able to deliver adequate power in short bursts to handle a variety of heavy-duty tasks.


2) Allen Wrenches


When choosing Allen wrenches, make sure that they have a lifetime warranty. These handy tools are used to remove a tight screw to avoid harming the screw heads. Make sure that the type you select is of higher quality. Lesser-quality models tend to round off the corners of the wrench, resulting in stripped bolt heads and turning a simple operation into a nightmare.


3) Magnetic-Tipped Screwdrivers


You probably already have a terrific screwdriver set, but do you have screwdrivers with magnetic tips? These great tools have multiple uses. They are especially useful when working with very small screws or odd mounting bracket angles. The screwdriver's magnetic tip gently grips the screw to keep it from falling, even if your grip or alignment slips while twisting to fasten it.


4) Wrenches and Sockets

Wrenches and sockets are essential tools for field techs and DIY projects. Your best option is a universal socket wrench. Dia Grip socket wrenches are made of Chromoly steel for exceptional strength and are a reliable and lasting tool for a variety of applications. Having multiple tools in one serves a lot of purposes. It will save time by eliminating the need to search multiple tools as well as save space in your toolkit.


5) Measurement Tape


Measurement tapes are useful to help technicians measure the lengths of items that they want to cut. Most field jobs may be completed using a simple retractable tape measure, but specialized tape measures are available to make the process easier.


6) Pliers


Pliers are an indispensable tool for any toolbox. They're mostly utilized for cutting wire, as well as grasping, twisting, bending, and straightening it. Any prepared technician keeps a variety of pliers in their toolbox. Make sure you have the following to be prepared for any situation:

  • Needle nose pliers
  • Side-cutting pliers
  • Reaming pliers


7) Flashlight

A flashlight may seem unusual to include on a list of essential tool kit items, but it is a crucial addition to your kit. These hand tools are useful for finishing jobs in dark areas, such as lofts. They also aid with the illumination of difficult-to-see areas including behind sinks, pipes, and cupboards.


8) Earplugs, Goggles, and Gloves


Accidents can happen anywhere and anytime. Make it a habit to wear protective gloves, goggles, and earplugs to avoid this. Because flying debris and loud noise can be harmful to your eyes and ears, it's critical to make sure you're properly protected at all times. These tools won't take up a lot of space in your toolbox, but they're necessary for whatever job you're working on.


9) Hammer


Every toolkit should include a classic builder's claw hammer. Try holding a couple of different brands and notice how different they feel. Choose the option that feels comfortable in your hand and is within your price range. Make sure that the weight is manageable as well.


10) Screwdrivers

This is the most obvious item on the list. Screwdrivers are useful for a variety of household tasks, such as replacing the battery from a smoke alarm or securing a wobbling doorknob. Purchase a set with an array of shapes and sizes. You can also get a reversible set with both Phillips and flathead alternatives.


11) Crescent Wrench


The crescent wrench is a width-adjustable wrench with a sliding jaw that adjusts the wrench's width. This means that you can use the same tool on nuts and bolts of various sizes. When utilizing a crescent wrench, keep in mind that the movable jaw is on the side where the rotation will be completed. 


12) Bubble Level (Level)


The bubble level is commonly thought of as a carpenter's tool. However, one of the most usually overlooked issues with a broken appliance is that its feet aren't level. A washing machine that isn't level rattles and produces alarming noises that can cause it to leak. Levels are the right tools for a job like this.


13) Cable Ties

These low-cost fasteners, often known as zip ties, are ideal for tying electrical cables or wires together. They are extremely useful for keeping an area clean and orderly.


14) Duct Tape


Duct tape is a versatile tool that will be used for your daily work in the field. It's a basic but useful tool to have in your toolbox. Duct tape comes in many different varieties, some of which even have a waterproof backing. You'll see the value of duct tape once you're on the job.


15) Utility Knife


You'll be amazed how often you'll require the use of a utility knife. A utility knife is a great workhorse when it comes to opening boxes, carving marks, and cutting through thick bindings.

Make sure the utility knife can be retracted. Make sure the blade is exceptionally sharp; a dulled blade will give you a lot of trouble. Although using a utility knife isn't difficult, extreme caution is required when working with such a sharp blade. 




The list above will come in handy while putting together your kit. To make your life easier and your task more efficient, consider adding the missing items to your list.
