At HDH Instruments, we specialize in providing new manufacturing, repairs, and conversions for the oil & gas Bottom Hole Assembly (BHA) rental market. Across the nation’s drilling hotbeds, from Pennsylvania to Louisiana to West Texas to Wyoming and North Dakota, HDH proudly serves Original Equipment Manufacturers (OEMs) and rental tool providers looking to replenish or refresh their fleets of common rental tools, such as:

  • Non-Magnetic and Low Alloy Drill Collars (Slick, Spiral, or Flex)
  • Filter Subs
  • Lift Subs
  • Stabilizers
  • Crossovers
  • Pup Joints
  • UBHO Subs

Whether looking to make new tools from solid bar requiring our deep hole drilling capabilities or converting tool sizes by enlarging diameters on existing components using our one-of-a-kind push and pull boring processes, HDH has you covered. With the capability to also support your roller burnish needs on non-magnetic tools, clients are able to avoid the logistics headache of having to send to multiple suppliers by using HDH Instruments.

HDH does not only provide straight ID’s either. We are able to provide multiple stepped diameters with stringent depth controls as well as custom transitions between bores when needed. We excel in working with our customers to come up with the most effective solution to meet the physical demands of their BHA tools while minimizing cost. Contact a sales representative (hyperlink to contact page) to see how HDH can help.

Not only can HDH re-size internal diameters, our full compliment of manual and CNC turning services allow us to deliver a one stop shop for your conversion needs. Whether taking a 31 ft slick collar and converting it into a flex collar, or just needing a 2 ft crossover profiled to size, HDH Instruments can cover it all.
