The Cutting Wheel is what makes Perforators so convenient. As it rotates down the Casing each tooth punches a hole about 1” X 0.25”, resulting in a straight column of perforations. HOLTE Cutting Wheels are heat-treated and carburized to ensure durability.
The Rig applies the force required for the Wheel to puncture the Casing and a thinner blade Wheel is available for Rigs with less pulldown or if easier and smaller perforations are desired.
Perforators also work on PVC with a special Cutting Wheel designed to puncture PVC using a fine tooth and a slower perforation rate.
