Wrenches

This wrench allows you to organize your tools in a way that makes it easier to find the right one at any given time. It also comes with a carrying case that can be easily stored when not in use. You can choose from 7 options to buy the perfect set that suits your needs.

Wrenches are essential tools for any self-respecting engineer. They are vital for turning nuts and bolts and are incredibly useful for any task that needs you to 'get a grip' on something.

Wrenches come in a few 'flavors,' with each type being more specialized than others; some are for specific tasks. They include the following, but in reality, you'll want to have a collection of each (or get a decent set).

Saw

This circular saw comes with a powerful 15-amp motor that gives great speed for faster cuts, Then, there’s a spindle lock for easy blade changes. The dust blower ensures you get better visibility.

A good saw is essential whether you need to cut wood, stone, or anything else. They come in a variety of forms but generally fall into either the toothed blade or disk types.

Saws tend to come in specific sizes and shapes and can either be hand powered or motorized for maximum cutting power.

The good old-fashioned hand saws are the most common and the simplest/most satisfying to use, in our humble opinion. These are ideal for small tasks, wood cutting, and of course, living out your dream of becoming a 'proper' lumberjack.

Jigsaws are great all-purpose saws that are perfect for cutting awkward shapes like curves but can also be used to cut straight lines.

Circular saws are power tools that come in cordless or corded varieties. These tend to be used for more hardcore cutting like masonry and metal cutting.

There are also band saws that are powered by a single motor and use a continuous band to cut through anything (within reason). These tend to be used for cutting meat, metal, and wood.

5. Jumper cables are always handy

Spirit Level

The Spirit Level tool is a versatile device that can be used to measure angles on multiple surfaces. It has a vial that adjusts to the angle of the surface it is being used on. Built to last for a long time.

If you want to make sure something is perfectly level, or vertical for that matter, you'll want to get yourself a decent spirit level. Although there are a plethora of smartphone apps out there, you might not want to get your phone dirty or risk damaging it.

Spirit levels come in various forms, but good ones will generally have unbreakable vials with some form of magnification and luminescent fluid. You'll also want to make sure they have a low tolerance which should be specified on the device for normal and reverse positioning.

You will also want to make sure they have a strong profile weight; 500g/m is usually considered enough.

10. Every engineer needs a good hammer

It is also available in various sizes so you're sure to find one that suits your needs. This tool is made out of high-quality material and has a durable handle that provides a firm grip.

A chisel is a relatively simple yet indispensable tool. They consist of a chunk of metal, usually with a wooden, plastic, or rubber handle, that has a beveled cutting edge designed for cutting and shaping stone, wood, or even metal. Chisels, like other tools, are ancient in origin and have stood the test of time.

They are primarily intended for use during pairing, joint cutting, or carving out materials for many tasks ranging from sculpting stone to carpentry.

They come in a variety of shapes and sizes, with some specialized for heavy-duty work like fence-building and frame construction which tend to have more robust rectangular cross-section blades.

They also vary widely in width, length, and the hardness of the blade material. You'll want to have a nice selection of different shapes and sizes, but a good chisel will last you a lifetime though you might want to invest in Whetstone, or other sharpening devices, to keep the cutting edge sharp.

19.2.jpg
Power Drill

The versatility and ease of use of this cordless drill have made it one of the most popular tools today. It is also easy to carry around since it doesn’t require any cords or outlets. It sports a soft grip for ease of working.

When muscle power just isn't good enough, power drills come to the rescue. They are very versatile tools primarily designed to provide powered assistance when drilling holes or driving screws into things.

They can either be cordless or corded and are ideal for drilling/screwing into metal, plastic, wood, brick, stone, concrete, glass, and tiles. They will tend to come with a set of varying lengths and types of drill bits (more on those later).

They usually come equipped with a slip clutch that allows you to adjust the amount of torque applied to the 'business end' of the drill.

"Drills may have a fixed speed setting, 2-speed settings, or variable speed depending on how hard you squeeze the trigger. Variable speed is most convenient as it allows a drill hole to be started easier without the bit moving all over the place. Also, lower speeds should be used with larger diameter bits to avoid overheating the bit due to friction." - Dengarden.

The right drill for you will depend on the task at hand, so you should do some research before buying one.

20. You'll also need some decent drill bits to go with that drill
