4" & 6" Well Developer Surgeblock Set
Description
Both the 4-inch, 5-inch and 6-inch use the same tough ABS body and molded 1.5-inch steel female NPT pipe fitting for attaching to a weighted wireline or drill pipe. Although the casing/screen wipers are also made of tough polyurethane, there are four wipers on each ABS body to ensure that the tool only needs to go in the borehole one time. The wipers can easily be replaced in the field with a regular slotted screwdriver to remove the stainless steel bolt and slide the spacers on and off the ABS body to replace or change wiper sizes (4-inch or 6-inch).
