Sure Cut Systems
The Sure Cut Exothermic Cutting System will cut virtually any metal, both ferrous and non-ferrous, and it is faster than conventional Oxy / Fuel Gas torches or carbon arc gouging. Exothermic cutting requires no preheating or cleaning the material prior to cutting. It is easy to use and is cost effective for most applications. Unlike carbon arc gouging, the Sure Cut System leaves no carbon residue on material being gouged.
For fire/rescue and demolition work, the Sure Cut System affords the operator the safety of standing out of harm’s way while cutting material that is under tension and likely to move when cut. For example, when cutting a support column in a collapsed building, the operator can cut a window in one side of the beam and reach through to cut the backside while standing in a safe location. Using the 3/8” Quick Connect rods, the operator has the option of joining two rods together and being able to stay further away from the material being cut.
Piercing / Removing Frozen Pins
Sure Cut rods are ideal for removing frozen pins from heavy equipment. By piercing a hole through the center of the pin, you heat the pin up from the inside. Piercing also removes enough material from the center of the pin to allow the pin to shrink for easy removal.
Time / Work Study
When removing a frozen pin from machinery the ID of the pierced hole in the pin depends on how tight the pin is and how much it needs to shrink. Some pins will come out with a hole slightly larger than the diameter of the rod being used. Pins that are really tight may require more metal removal to allow them to shrink enough to be removed.
Pierce an 1 1/4″ X 12″ long frozen pin; 1/4″ X 24″ Sure Cut Rod; 16 seconds to pierce.
Removing a 2.5″ X 8″ pin from crane boom; 3/8″ X 36″ Sure Cut Rod; 9 seconds for pierce. 40 seconds enlarging the ID of the pierce. After cooling pin was removed with a few blows from a hammer. Total time with cooling 10 minutes.
Removing a 4″ diameter X 12″ long pin from crane boom; Required 3 each 37B36QC rods. Initial pierce took 20 seconds. Increasing the ID of the pierce was 5 minutes. Cooling time was 25 minutes and the pin was removed by hand.
Removing a 5″ diameter X 16″ long pin from a papermill roll; Required 6 each 37B48 Sure Cut Rods. Initial pierce took 35 seconds. Enlarging the ID of the pierce took 15 minutes. Cooling time and removal 30 minutes.
- Cutting 1/4″ steel plate; 3/8″ Sure Cut Rod; 5 feet per minute.
- Cutting 3/8″ steel plate; 3/8″ Sure Cut Rod; 4 feet per minute.
- Cutting 1/2″ steel plate; 3/8″ Sure Cut Rod; 3 feet per minute.
- 3/8″ thick Stainless Steel Plate; 3/8″ Sure Cut Rod; 2 feet per minute
- 2″ thick X 8″ wide Aluminum Bus Bars; 3/8″ Sure Cut Rod cut in 45 seconds.
Gouging; Sure Cut rods offer a faster, quieter method of gouging steel. With a 3/8″ Sure Cut Rod a single pass on 3/8″ deep X 24″ long plate takes 10 seconds. Gouging a 3/4″ fillet weld to the root and separating the plates took 40 seconds.
Results will vary according to Position of cut, Chemistry of the material, Hardness of the material as well as Operator ability.
