Drillers always drill a smaller hole at first, then enlarger
it with hole opener, it is a type of regular drilling technology when the
drilling machine is lower power or the end-hole is too big
We can make the hole opener and solutions according to the
hardness of rocks, drilling depth, size of pilot hole, size of end-hole
If fix the tricone bits as the pilot bits, the hole opener
will be a rock bits, hole opener with tricone bits as pilot bits is always
applicable in special sizes well drilling .The reamer mainly consists of four or more cones
Cutting structure with premium tungsten carbide hard facing
or premium tungsten carbide insert of formulas and new techniques is utilized,
and increases wear-resistant capability of reamer
