The Toro Downhole Tools - Shock Subs are designed to provide maximum protection against BHA vibrational damage while keeping the drill bit firmly on the bottom. Toro shock subs are engineered to reduce severe vibrations caused by hard formation drilling. By eliminating drill string bounce, the Toro Shock Sub helps to reduce drill string connection fatigue and prolong drill string life.
Toro offers two types of shock subs:
- SM series: Mechanical shock sub
- SH series: Hydraulic shock sub
The Toro SM Shock Subs are mechanical by design for maximum durability and reliability. The Toro Shock Sub features a spline assembly encased by a multi-layer of high strength disc springs. The shock subs are fully sealed preventing the drilling fluid from contacting the internal mechanical components. Toro SM Shock Subs feature a large inner diameter for high flow rates and for passing wireline or other equipment through the center bore.
The Toro SH Shock subs are fully hydraulic and features a spline assembly encased by a hydraulic piston and reservoir. The SH shock subs are fully sealed preventing the drilling fluid from contacting the internal components.
