The main roll shapes of piercing mill are disc roll, barrel roll and cone roll. The disc roll is seldom used, and the barrel roll and cone roll are commonly used.

The maximum diameter and length of the roll body are determined according to the length of the roll, rolling speed, biting conditions, rolling product specifications, power consumption and the number of roll trucks.
