  • Drill Master: Understanding Bend Radius - Trenchless ...

    2002-6-1 · Bend radius by definition is the forward distance required for a drill string to make a 90-degree turn (see figure on pg. 61). In practicality, bend radius is an indication of how much bending a pipe can take without doing significant damage to the drill stem. In the past, drill pipe manufacturers used different methods to establish the bend radius rating for the their pipe.

  • Choosing Drill Rods for Trenchless Tunneling

    2017-12-12 · In addition to calculating the total length, the bend radius of the drill rod is also calculated. Essentially, the bend radius is the forward distance a drill string must make to make a 90-degree turn. The exact calculation to determine the bend radius of a rod varies from manufacture to manufacture. However, exceeding the calculated variance damages the rod.
