Recently, I've found that everyone is particularly interested in the blade. Then we'll just talk about a few more blades.
So today let's talk about the rotation file first.
(Here it is)
Let's talk about that first, what is the so-called "file" talking about?
The cutting heads shown in the picture are files, which is the general term for this type of cutting heads.
Compared to other cutting heads, the biggest difference between a file and other cutting heads is that its cutting head has multiple blades, that is, a multi-blade cutting head. The blades we usually use are mostly double-edged.
It is thanks to the many blades that the blade will not bounce when used. In short, it's one word - "stable".
When making relatively hard woods such as ebony and rosewood, it is also very good to use a file for this.
It is worth noting that the file is also divided into single and double grooves. Double slots are more stable than single slots.
Files of this type are mainly made of alloy or tungsten steel, which makes them more durable.
In everyday work, if there is sawdust in the file that sticks to the grinding head, it can be cleaned with a wire wheel. the blade will become much sharper.
When carving wood, files are mainly used for smoothing. To remove unnecessary marks from a knife, the effect is about the same as from a scraper.
It is not possible to use a file for shaping, but it is too slow to cut the material. Therefore, it is still not recommended to use a file to beat off the embryo.
