Frequently Asked Questions
Q: What formations are most suitable for the 8 1/2" Milled Tooth Bit?
This bit is specifically designed for soft to medium-hard formations, providing the optimal balance of speed and durability for these specific ground conditions.
Q: How do I prevent bit balling during drilling?
Our bit features a high self-cleaning design and 3 strategic nozzles that flush out cuttings efficiently. Ensure proper fluid flow rates to maximize this effect.
Q: Can I use maximum RPM and WOB simultaneously?
No. As per our technical notes, the upper limits of Weight on Bit (WOB) and Rotations Per Minute (RPM) should not be used simultaneously to prevent premature wear.
Q: What is the advantage of the Journal Sealed Bearing in this bit?
The Journal Sealed Bearing combined with Rubber O-Rings ensures that lubrication remains inside the bearing while keeping abrasive drilling mud and debris out.
Q: Is this bit compatible with standard API rigs?
Yes, it features a 4-1/2″ API REG connection, which is a global industry standard, ensuring compatibility with most professional drilling equipment.
Q: How does the Milled Tooth design compare to TCI bits?
Milled Tooth bits generally offer faster penetration in softer formations and are more cost-effective, whereas TCI (Tungsten Carbide Insert) bits are used for harder rock.
