Frequently Asked Questions
Q: What geological formations are best suited for Milled Tooth Bits?
Milled Tooth Bits are ideally designed for soft to medium-hard formations where high drilling speeds and efficient cuttings removal are required.
Q: How do I prevent bit balling during well drilling?
Our 17 1/2" bit features a strong self-cleaning ability and a 3-nozzle system to effectively flush away cuttings and prevent clay buildup.
Q: Can I use maximum WOB and RPM simultaneously?
No, for optimal tool life and performance, the upper limits of Weight on Bit (WOB) and Rotations Per Minute (RPM) should not be used simultaneously.
Q: What is the advantage of the Journal Sealed Bearing?
The Journal Sealed Bearing, combined with Rubber O-Rings, protects the internal components from drilling fluids and debris, ensuring smoother rotation and longer service life.
Q: Is the 7-5/8″ API REG connection compatible with most rigs?
Yes, the API REG connection is an industry standard, ensuring compatibility with most professional drilling equipment and drill rods.
Q: How is the net weight of the bit managed during transport?
With a net weight of 222kg and a gross weight of 239kg, our bits are securely packaged in reinforced dimensions (504767mm) to prevent damage during transit.
