I would digress for a moment – there has been a lot of discussion on Reddit regarding mechanical pencils. Some folks fall in love with some model and they are still using the same for 5-6 years and didn’t like to get their hands on any other version. While some people have changed their loyalty to other models.
That said, choose Zebra M-402 only if you want to change your taste, otherwise, the first two reviewed are most widely used for doing mathematics. Let’s see what it brings to its buyers?
The Zebra M-402 is a classic mechanical pencil with stainless steel build and great precision level, the pencil is great regardless of the fact that it is not much used for doing the math. You are getting a soft rubber grip for a firm hold. Some pencils that have a hard plastic grip are hard to hold after some time, they are even worse for the sweaty hands. So, if you want a steel finish and that with a comfortable fit in your hand; Zebra M-402 should be the primary choice.
It is great as far as it is concerned to take notes, do homework or make an assignment, however, I wouldn’t rate it for doing the math.

0.5 or 0.7 Which One is Better?
Each mechanical pencil differs in lead size. The size of the lead is usually written on the pencil itself. The most common lead size is 0.5 mm and it is the favorite lead size for writing purposes. The manufacturers are shifting towards 0.7 mm but it is not much popular for writing, however, it is an ideal size for sketching purposes. As mentioned before, 0.5 mm lead size is majorly used for writing so you can get this size for doing maths as well.
Can you use a 0.7 mm lead size on a 0.5 mm mechanical pencil?
This question revolves around a majority of the folks using mechanical pencils. First of all, it doesn’t make sense to do so. You would most probably break the lead when using a pencil. The 0.7 mm lead wouldn’t have enough room to rotate in a 0.5 mm mechanical pencil. The same is true for using a 0.5 mm lead in a 0.7 mm pencil. The only solution is to buy the correct lead size.
If you want my honest opinion, I would suggest you keep a 0.5 mm pencil with you because it is the most popular size therefore easy to replace. On the contrary, if you carry an uncommon size with you, you will have a difficult time finding a lead replacement. Therefore, my suggestion is to go for the size that is easily available all the time. For more details, check out this wikiHow guide on choosing the right lead size.
