Designed For Dual Rotary Drilling:

Dual Rotary Drilling Uses Two Rotary Drive Mechanisms—One Rotating The Drill String and The Other Rotating The Casing—To Deliver Exceptional Performance in Overburden and Hard Rock Formations.

Performance Benefits:

• Drills Efficiently Through Boulders, Ledge, And Bedrock
• Reduces Sidewall Friction for Improved Depth Capabilities
• Protects Casing from Damage, Splits, And Premature Wear
• Improves Penetration Rates in Challenging Formations
• Extends Tooling and Casing Life

Button Design Advantages:

Domed Buttons:

• Maximum Resistance to Breakage in Hard Rock
• Smaller Carbide Buttons Tend to Provide Faster Penetration but May Wear Out Sooner in Hard Rock
• Ideal For Long Life in Abrasive Formations

Rear Ballistic Buttons:

• Increase Borehole Reaming Action
• Improve Gauge Protection
• Enhance Overall Shoe Longevity Through Difficult Formations
