The Drilling Tools Shock Sub has been developed to absorb shock and vibration and vertical bit displacement in
drilling applications. This gives the driller more freedom to select optimum WOB and rotary speed, resulting in
faster penetration rate. Reduced shock and vibration extends the life of the bits and MWD/LWD tools as well
as the entire BHA. Proven in directional and vertical drilling in both MWD and air applications, the Drilling Tools
Shock Sub enhances the BHA in all types of drilling.
TripSaver II Shock Sub
• Robust Drive Train Design – Proven reliability,
reduced manufacturing and refurbishment costs.
• Unique Spring Assembly – Self-adjusting
spring range provides ultra-light to heavy
weight loads.
• Vibration Dampeners – Proprietary materials
strategically placed throughout the tool for
axial and lateral vibration control.
• Double No-Go’s – Upper and lower No-Gos ensure
tensile over pull is distributed simultaneously and
evenly throughout the tool.
• Triple Overstroke Protection – Lower, middle,
upper impact positions insure G force is distributed
evenly across the sub.
• Quality Control – In-house testing measures
simulate hostile drilling environments, insuring
optimum performance.
