Near Bit Reamer (NBR®) Borehole Enlargement Tool
The NBR borehole enlargement tool can be activated while drilling to enlarge the bore hole up to 20% of the pilot hole diameter.
Sledgehammer™ Hydromechanical Drilling Jar
Reduces downtime and is suited for hot-hole applications and extended-reach drilling.
UnderReamer Heavy Duty Borehole Enlargement Tool
A heavy-duty tool for enlarging the borehole significantly beyond the bit diameter.
XR™ Reamer borehole enlargement tool
The XR reamer tool provides reliable hole enlargement while minimizing BHA vibration and can be deactivated to improve cleaning while tripping out.
