17.1/4” VM-28G - Vanguard™ Technology
The keys to maximimum performance in any application are:
• Engineered cutters combine application-tuned carbide grades with aggressive tooth shapes for faster rate of penetration (ROP).
• Mathematical models improve cutter arrangements to reduce tracking and increase ROP.
•High-strength legs and enhanced outside-diameter (OD) protection prevent severe leg wear in directional applications.
•Industry leading bearing and seal reliability with the High Aspect Ratio (HAR) and Metal Faced Seal bearing packages.
• Engineered cutters with advanced carbide grades to maximize ROP and durability
• Stabilized HAR bearing seal to enhance bearing and seal reliability
• Metal Faced Seal to improve reliability in high RPM and high temperature applications
• Computer-modeled cutter arrangements to increase drilling efficiency
• Superior bearing grease to improve bearing load capacity
• Shirttail and leg hardfacing to strengthen legs and minimize leg wear
• Center Jet feature
• Performance drilling operations in medium to hard rock formations
• Rotary and motor applications
