The Thread-on SD Housings are compatible with the patented FastBack® Direct Pullback System. These housings are heat-treated with chrome-nickel-moly alloy steel just as our bolt-on transmitter housings. The Box by box design provides unmatched versatility and value so you can use your Eagle Claw SD, Iron Fist or bolt-on blades (using a bit body) with one housing. The stainless steel timing mechanism makes clocking the transmitter to the bit a cinch. The straight-through gun-drilled fluid ports make the transmitter housing easy to clean.

FREQUENTLY ASKED QUESTIONS
Short Answer: A Thread-On SD Housing is used for pilot bore drilling with threaded directional bits in tougher ground conditions.
Correct use: The Thread-On SD Housing is installed at the front of the drill string for pilot bore operations where threaded bits are preferred over bolt-on blades. It is commonly paired with bits such as Tri-cutter or cobble bits for more robust drilling applications.
Technical details: The threaded connection provides a solid, continuous interface between the housing and the bit, making it well suited for harder or less forgiving ground where higher loads and impact are expected.
Incorrect use includes: Using the housing with blade-style steerfaces or outside of pilot bore operations. Incorrect use can introduce greater risk of poor fit or reduced drilling efficiency.
Short Answer: Thread-On SD Housings are compatible with threaded directional bits designed to match the housing's thread type, gender and size.
Correct use: The housing should be paired with threaded pilot bits such as Eagle Claw, Iron Fist, and other compatible threaded bit styles. The thread type and orientation must match exactly to ensure proper fit and load transfer.
Technical details: Compatibility is determined by thread size, thread type, and transmitter fit rather than bolt patterns. Using correctly matched threaded components provides a stronger interface for higher-load pilot drilling applications.
Incorrect use includes: Mixing incompatible thread types or attempting to adapt blade-style steerfaces to the housing. Incorrect use can introduce greater risk of thread damage, loosening, or connection failure.
Short Answer: A Thread-On SD Housing is best suited for harder ground conditions and less forgiving formations.
Correct use: This housing is commonly used in clay, hardpan, mixed ground, and other tougher soils where threaded directional bits provide improved durability and penetration. It is intended for pilot drilling scenarios where added strength and stability are required.
Technical details: Ground performance is influenced by the threaded bit attached to the housing. The threaded connection supports higher loads and impact forces, making it better suited for demanding ground conditions than blade-style systems.
Incorrect use includes: Running the housing in soft ground where blade-style steerfaces would provide better steering control or using it without a bit matched to the formation. Incorrect use can introduce greater risk of inefficient drilling or unnecessary wear.
