Hello, everyone.
This is Enta.
Actually, I was on a live broadcast on Ameba TV the other day lol
Is It a Bad Idea to Jump In to Help? How Do You Rescue a Drowning Person? We Ask a Former International Rescue Team Member
That’s why I agreed to appear on the show—based on my past experience of saving a friend.
You never know what might happen when you post stuff online, lol.
Since I was appearing on Zoom from home, I felt kind of relaxed and was able to speak comfortably.
Thank you for the wonderful experience.

But that's beside the point.
Following up on what we talked about the other day, have you come up with anything?
The chips were flying off, and the drilling speed increased!
Let's assume that 1 is a normal bit.
2 is the bit where the chip flew off.
The difference, you ask? It's the number of chips.
Option 2 drills faster.
There's a reason for this: there are 9 and 6 chips hitting hard rock, respectively.
For example, the force exerted on a single chip when it is held down with a force of 1,000 kg is
1. 1,000 kg ÷ 9 pieces ≈ 111 kg
2, 1,000 kg ÷ 6 units ≈ 166 kg
Number 2 is stronger.
Number 2 has more hitting power!
Simply put, it's a question of whether to tear the washi paper on a shoji screen by pressing with the palm of your hand or with your fingertips.
That means a concentrated point load!
The downside is that wear is faster at level 2, lol.
However, in the end, it turned out to be a very quick process and a great learning experience.
If you find that the material is just too hard and drilling isn't progressing well,
We recommend using a new bit with fewer chips.
It wears out quickly, but the drilling speed is decent^^
It’s a shame when it’s just too hard, but,
It might be fun to try knocking a couple of bits off the chip with a hammer, lol.
See you later.
