A-0503 is the weld seam removal disc from TFT-PNEUMATIC Safety Tools. It is the most important part of the only handheld certified Cold Cutting System of its kind. Used mostly to remove welds such as double plating and welds securing equipment too decks and so on. These are just a small number of possible uses. The cuts are straight and clean, but most importantly can be done flush to the deck or other surfaces eliminating completely any material from the surface. Please see the videos below showcasing this. Clean up is safe and easy because all the large, blunt fragments fall within a few inches. It can be used as a handheld tool or as part of a track system such as A-0410 or A-0420. The average disc lifespan with the handheld version is up to 40 feet in length (5/16″ – 1/2″ depth). Using one of our track systems can increase its lifetime by up to 50%.
Certified Cold Work Tool
TFT-PNEUMATIC Safety tools are Classified as Cold Work Tools and Certified by DNV for use in Potentially Explosive Atmospheres. No other tool gives you greater protection. Our tools do not require Hot Work Permits, Habitats, or Fireguard.

We have two different profile cutting discs. A thin 5 mm cutting disc (A-0502) or a thicker 10 mm weld seam removal disc (A-0503). Depending on the application one may be more suitable than the other. For instance, the weld seam removal is designed to be run parallel to a deck and remove flush structures that may have been welded on. This is something that sets it apart from sawzalls and other traditional tools.
For cutting into pipe or storage tanks the cutting disc is much better, a smaller width will allow for less material removal. The ability to cut into a storage tank which may contain explosive materials without risk is second to none. Our tools have been used around the Globe in tanks where the contents were unknown giving the Operator and Asset Owner Ultimate Protection.
Other jobs where perhaps a Lock-tag could have been by-passed would have been safer with our tools in the first place. While not the fastest tool in the market, they are definitively the coolest and the safest.
These rotating files (can also be called grinding burrs or rotary files) are designed to be an extension of the Operators arm. They feature low vibration during operation, low heat, and low noise levels. The metal fragments are large, sharpless, and will drop just a few inches away from the work piece, making the worksite safe, and its cleanup easy and fast.
For material removal jobs in Classified Areas, you need tools that are Certified Cold Work, to avoid spending in Hot Work Permits, Habitats and fire watches or worse, shutdowns and delays. Our tools have been used for more than 15 years in the toughest places around the World.
The TFT-PNEUMATIC Safety Tools rotating files and discs are made of a proprietary alloy based on tungsten carbide. The hardness in their Patented design is right in between the one of an industrial diamond and the one from a natural diamond. Depending on the job you may select the type to use: surface prep, grinding or cutting.
TFT-PNEUMATIC Safety Tools rotating files and discs are reliable and safe to use in explosive environments, such as Offshore Platforms, Refineries, Chemical Plants, mines, and many other places. These tools are robust and built for heavy-duty industrial jobs. Their lifespan is up to 100 times the one of a traditional carbide file. Since our files do not heat up significantly, they do not lose their sharp edge. In 15 years no users have complained about the file’s lifetime. Most of our users praise the ability for both the tools and attachments to be in pair with the toughest jobs in the Industry.
The tools have endured a long and tough Certification process by DNV. They have proven throughout this testing and for more than 15 years in the toughest conditions, that they will not trigger an ignition. Used day in day out in the toughest places in the world they are a valuable asset for small to medium jobs where mobility and speed are important.
By using these certified cold work tools, you can avoid all the hassle from a Hot Work Permit or Habitats. The tools can be used in hydrocarbon-rich environments, where gas is present without all the dangers associated with using hot work tools. Our tools are so cool in fact that they can be used directly in contact with the hydrocarbon/gas. While not the economical tool as a standalone item, their ability to be used at all times, allows the Asset Owner to recover the investment many times over in as little as a few minutes of use.
Being certified cold work tools means you do not need to cover up adjacent surfaces in the work area because the tools do not produce any hot sparks that can burn through paint coatings. The work area temperature is low heat, averaging 95-105°F when grinding steel, which if you think about it is just above human body temperature. Our tools are also certified for Dust Explosive atmospheres.
There is no escape of isocyanides when grinding through polyurethane coatings with traditional tools. However TFT-PNEUMATIC Safety Tools chip off the material, rather than burn it. This is accomplished by reducing the energy, thus reducing the heat. This means the Operators will not breathe these harmful chemicals.
