Holte Perforator -
Perforates the Inside Walls of
Installed Steel & PVC Well Casing Drill String

20+ Years of Making Perforators Gives Holte Experience

The Holte Perforator effectively perforates the inside wall of installed steel and PVC well casing in a variety of situations. The simply designed body allows the 4”, 6” or 10” unit and adapter to be quickly threaded onto your drill string through the use of standard subs.  Air or water engages the 6 - point cutter wheel while down pressure from the rig makes the wheel rotate and perforate to the desired depth.  Puncture size is adjustable by several methods to ensure the desired end result is achieved.

Parts Designed to Last

Newly designed, precision machined and carbon treated body ensures precision fit of internal parts.  This results in extending the life of parts that wear as they are not able to warp under the high stresses experienced during usage.

Standard units are designed to perforate up to .375” wall pipe and can be adapted for up to .500” wall. 

Slide shoes adapt perforator units to puncture well and hole casing close to the nominal size of the perforator while roller shoes are used above 10" to ensure the casing is not able to distort and reduce control of perforations.

Holte stocks a full line of adapters and replacement parts available for same day shipping. 

Available in the following sizes:

4" perforator units with adapters to 5" casing.
6" perforator units with adapters through 12" casing.
10" perforator units with adapters through 26" casing.
Larger sizes are also available for custom applications.
