Relationship between bit diameter and rotation speed
If the bit is drilled at a low velocity, the drilling efficiency will be low due to the low line speed, and the drill bit will be easily broken due to the small size and the small strength of the drill bit. But because the bit in drilling, large diameter, high speed, line speed will be very high, the bit will be very easy to damage on sticky steel drill.
Secondly, it is related to the grinding, feed size, material and so on. Such as: stainless steel drilling, the drill speed and feed volume should not be too large, the need for flexible use.
There are many factors affecting the size of the drill bit and the speed of the drill. Theoretically, the speed of the bit is mainly the linear velocity of the bit, because the diameter of the bit is small and the speed of the bit is low. The diameter of the big drill is big and the line speed is high.
