What is a honed tube?

Honed tube is usually a CDS (Cold drawn seamless) steel tube or DOM (Drawn Over Mandrel) steel tube with inside diameter honed or skived &roller burnished, so honed tubing is with extremely precise ID dimensions and smoothly ID surface.

"As the leading hydraulic cylinder honed tube suppliers, Our factories can produce honed cylinder tubes in a wide range of metric sizes and imperial sizes. metric sizes Inside Diameter 32mm to 600mm; Imperial sizes equally."
