The polished drill has four edges that can be stabilized while drilling.
These two additional “polishing” edges also help to make the hole more complete than the conventional bit after cutting the edge of the cut. They also help to form a hole from one to the other. Since the polishing edge actually moves the material back, the most important thing is to use the carbide to polish it first, it has the compressive strength, and only the highest quality.
The structure of the straight slot helps to break down the chip into smaller, more manageable sizes.
The solid structure makes the polished drill more straight and smaller than the regular twist drill.
Although we don’t do advertising, but it’s another benefit is to prolong the life of the tool, a lot of time to the customer for 3-4 times that of the conventional cemented carbide twist drill tool life, cemented carbide three flutes, even a moderate bit.
A polished drill has a simple look, but there are many invisible details that make it work. Excellent expertise has been developed over the course of 35 years, and they have been polishing the borehole so that it can be applied to the polished bit and make it work for the first time.
