FREQUENTLY ASKED QUESTIONS
Short Answer: A Bolt-On SD Housing is used to hold the locating transmitter and accept bolt-on directional blades for pilot bore drilling or direct pullback.
Correct use: The Bolt-On SD Housing is installed at the front of the drill string for pilot bore operations where bolt-on steerfaces are required for use of directional blades such as OEM, Borzall, or other directional blades. Pit Bull features come pre-installed, but can be used with Pit Bull enabled blades or any other style directional blade for use.
Technical details: Unlike threaded or non-threaded systems, the bolt-on design uses a fixed bolt pattern to attach directional blades directly to the housing. This provides a secure connection and consistent steering geometry during pilot drilling. Bolt patterns are specific to OEM designations.
Incorrect use includes: Using the wrong diameter housing without a properly matched bolt-on blade can introduce many risks. Incorrect use can introduce greater risk of poor steering response or connection issues.
Short Answer: Bolt-On SD Housings are compatible with bolt-on directional blades that match the housing's bolt pattern.
Correct use: The housing must be paired with bolt-on directional blades that mate the bolt pattern of the steerface. Pit Bull blades and other directional blades are all designed with specific bolt patterns specific to rig manufacturers, such as Ditch Witch or Vermeer.
Incorrect use includes: Installing a blade with an incompatible bolt pattern or mixing components intended for different rig manufacturers. Incorrect use can introduce greater risk of blade loosening, poor steering control, or housing damage.
Short Answer: A Bolt-On SD Housing can be used in a wide range of ground conditions depending on the directional blade installed.
Correct use: Ground suitability is determined by the bolt-on directional blade rather than the housing itself. By selecting the appropriate blade, the housing can be used in dirt, clay, mixed ground, and other formations encountered during pilot drilling.
Technical details: The housing's role is to support transmitter placement and blade attachment. Cutting performance and ground interaction are controlled by the blade design and material, allowing flexibility across varying soil conditions.
Incorrect use includes: Assuming the housing alone determines ground suitability or using a blade not designed for the encountered ground. Incorrect use can introduce greater risk of inefficient cutting, poor steering response, or accelerated wear.
