Threaded Bit Bodies

Short Answer: Threaded bolt-on bit bodies give drillers the option to run bolt-on directional blades on a threaded housing, then switch back if desired.

Correct use: These bit bodies thread into an existing housing or SD housing and allow the driller to attach bolt-on directional blades. This setup lets contractors convert a standard thread-on housing into a more versatile steering tool without replacing the housing itself.

Technical details: The male threaded connection provides a solid interface with the housing, while the bolt-on face accepts directional blades matched to the rig's bolt pattern. This combination expands tooling flexibility while maintaining a threaded drill string.

Incorrect use includes: Attempting to use threaded bolt-on bit bodies with threadless systems. Incorrect use can introduce greater risk of poor fit or connection failure.

Short Answer: Threaded bolt-on bit bodies are compatible with threaded housings and bolt-on directional blades that mate to the housing's front thread size and gender.

Correct use: These bit bodies should be threaded into housings or SD housings with matching thread types and paired with bolt-on blades with the same bolt pattern. Proper matching ensures secure attachment and consistent steering performance.

Technical details: Compatibility is determined by thread size and thread type. Threaded bolt-on bit bodies are not compatible with threadless connection systems such as Tri-Con.

Incorrect use includes: Mixing incompatible threads or attempting to adapt the bit body to threadless systems. Incorrect use can introduce greater risk of loosening, misalignment, or damage.

Short Answer: Threaded bolt-on bit bodies can be used in a wide range of ground conditions depending on the directional blade installed.

Correct use: Ground suitability is determined primarily by the bolt-on blade rather than the bit body itself. By selecting the appropriate blade, this setup can be used in dirt, clay, mixed ground, and harder formations encountered during pilot drilling.

Technical details: The threaded connection provides strength and stability, while the blade design controls cutting action and steering response. This allows drillers to adapt to changing ground conditions without changing housings.

Incorrect use includes: Assuming the bit body alone determines ground performance or using blades not suited to the formation. Incorrect use can introduce greater risk of inefficient drilling or accelerated wear.
