==HDD REAMER HAVING REMOVABLE CUTTING TEETH - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18432854 titled 'HDD REAMER HAVING REMOVABLE CUTTING TEETH

==Simplified Explanation==

The reamer for drill string pullback of a horizontal directional drill includes a shaft portion with vanes extending radially from the outer periphery, each vane having cutter teeth secured along its surface with PDC inserts joined separately. The cutter teeth are coupled to the vanes with removable fasteners.

* Shaft portion with central axis and first end for attachment to drill string
* Vanes with cutter teeth secured along outer peripheral tooth base surface
* Cutter teeth with body and PDC insert joined separately
* Removable fasteners coupling cutter teeth to vanes

== Potential Applications ==
The reamer can be used in horizontal directional drilling operations to enlarge the borehole and improve drilling efficiency.

== Problems Solved ==
1. Enhanced drilling performance due to the design of the reamer with cutter teeth and PDC inserts.
2. Facilitates the process of enlarging the borehole during horizontal directional drilling.

== Benefits ==
1. Increased durability and longevity of the reamer due to the use of PDC inserts.
2. Improved drilling efficiency and accuracy.
3. Easy replacement of cutter teeth for maintenance purposes.

== Potential Commercial Applications ==
"Reamer for Drill String Pullback in Horizontal Directional Drilling Operations" can be used in the oil and gas industry, construction industry, and infrastructure development projects.

== Possible Prior Art ==
There are similar reamers in the market with cutter teeth and PDC inserts, but the specific design and configuration of this reamer may be unique.

=== Unanswered Questions ===

=== How does the design of the reamer contribute to the efficiency of horizontal directional drilling operations? ===
The design of the reamer with cutter teeth and PDC inserts is intended to improve drilling performance, but the specific mechanisms behind this enhancement are not detailed in the abstract.

=== What are the potential challenges or limitations of using this reamer in horizontal directional drilling operations? ===
While the benefits of the reamer are highlighted, the abstract does not mention any potential challenges or limitations that users may face when utilizing this technology.


==Original Abstract Submitted==

A reamer for drill string pullback of a horizontal directional drill includes a shaft portion defining a central axis and a first end configured for attachment with a drill string of the horizontal directional drill. A plurality of vanes extend radially from an outer periphery of the shaft, each of the plurality of vanes defining an outer peripheral tooth base surface. On each of the plurality of vanes, a plurality of cutter teeth are individually and removably secured along the outer peripheral tooth base surface thereof, each one of the plurality of cutter teeth including a body and a PDC insert manufactured separately from the body and joined therewith. Each cutter tooth of the plurality is coupled to the respective one of the plurality of vanes by a removable fastener extending at least partially through the cutter tooth and at least partially through the one of the plurality of vanes.
