SE drill rods
Technodrill SE drill rods are manufactured from best quality cold drawn seamless steel tubes with end pieces from high tensile heat treated alloy steel.
A unique method has been specially developed by Technodrill to achieve the strong bond between the end pieces and the main tube. It is a combination of technical processes (induction shrink-fitting, welding with high quality special welding electrodes etc) that guarantee concentricity between the tube and the end pieces and provide drill rods extremely durable and resistant to wear.
The thinner walls of the main tubes compared to the strengthen walls of the end pieces make the drill rods lighter and easier to handle.
The longer unthreaded sections (shoulders) of the threads, work like guides that lead to smoother moves and also allow higher torque transfer than rods of same dimension.
An o-ring between the threads eliminates the leakage of drill fluids.
Suitable for deep hole drilling and demanding conditions.
Available in sizes 50 & 43mm.
