Combining the advantages of a modern underreamer with a compact size, the Drillstar Z-Reamer opens up new reaming applications. The simplicity and reliability of its design make it a reliable, cost-effective alternative to other modern underreamers. Due to its much shorter length, it is now also possible to perform directional reaming-while-drilling using PDMs rather than a RSS BHA, even in ...

Pilot Hole Reaming The REAMING operation consists of using an appropriate tool to open the pilot hole to a slightly larger diameter than the carrier pipeline. The percentage oversize depends on many variables including soil types, soil stability, depth, drilling mud, borehole hydrostatic pressure, etc. Normal over-sizing may be from 1.2 to 1.5 ...

The drill press RPM setting for reaming depends on the cutting speed of the material and the size of the ream. The RPM setting will change with the size of the ream. As the ream gets smaller, the RPM must increase to maintain the recommended surface footage. Although you will find specific cutting speeds for reaming, a simple rule of half the speed will work for most reaming operations. Using ...
