How Long Is Lifetime of Screw Drill?

Lifetime of screw drill is generally 150 to 200 hours, its weakness is the stator rubber at low temperature level, bearing easily damaged.

We are now stepping up research and development for manufacturing reliable bearing system and elastic material made of the stator, and this material may have wear-resistant and high temperature resistance, so that the screw drill working life has been significantly improved. And the development of low speed high torque applied to the screw to drill deep and ultra-deep hole.
