COBBLES

Cobbles are round, sometimes smooth, little beasts that are deceptively destructive to HDD tooling. Larger than a pebble but smaller than a boulder, these rounded rocks can put good tools to the test with their blunt force continually pounding downhole. Tooling that moves cobbles out of the way is usually a safter bed than trying to pulverize them.
