Rotary Drilling Technical Summary
The key to achieving optimal drilling performance lies in the Weight on Bit (WOB) and the rotation speed. Adequate WOB is crucial for effectively pressing the
Drilling mechanics and performance
Rotary drilling is a widely used drilling method for creating boreholes in the earth by employing a rotating drill bit attached to a drill string.
HDD Good Practices Guidelines
The final installment from this series takes a look at tools and accessories. With the introduction of higher capacity pumps and horizontal direction drilling (HDD) rigs with higher
Secoroc COP M6 down-the-hole hammer
Compressed air is led to the hammer via the rotation spindle and drill pipes. Exhaust air from the hammer is discharged through holes in the drill bit and used to flush clean the drill hole.
What Is A Rock Drill Used For?
At its core, a rock drill is a powerful tool designed to bore holes into rock, concrete, and other hard materials. Unlike a standard drill designed for wood or metal, a rock drill
Selecting the right bits for rotary drilling
The rotation in percussive drilling is best kept to a minimal value, and feed or down pressure should be sufficient to keep the bit fed to the
