Buying Guide on Best Mechanical Pencils for Engineers

Before buying a mechanical pencil for your engineering work you need to check the following criteria to ensure getting the best one.

Build quality

It always matters whether you are buying mechanical pencils or other products. It is very common to slip a pencil from your hands. A good mechanical pencil must have a metal barrel. So, it can handle regular drops. Also, it has to be thin enough for holding with comfort on the hand.


Either a latex-free rubber grip or a metal grip should be comfortable on the hand. However, metal grips are less recommended for sweaty hands. You can use a rubber grip instead.


This is the most important thing for doing a smooth drawing. I would suggest picking medium size lead. But you have to select on your own to get something that suits you the best for you. In general, 0.7mm lead is the best choice for engineers. It allows precise drawing every time.
