The Bit Release Joint is used in operations
for drilling out cement, cast iron bridge
plugs, composite bridge plugs, and
other drillable tools and thereby leaving
the drill string intact as the production
string. The spring loaded check valve
prevents tubing back-flow during drill
out. After drill out, a ball is dropped
through the drill string and seats in the
piston. Pressure applied to the drill string
forces the drill bit to release and fall to
the bottom of the hole.
Special Features
> Simple design
> Dual float option
> Full opening after release
> High shear option available
