A-0004 – is a small rotating file commonly used for removing sharp edges and following crack lines. Great for grinding inside pipes and obtaining different angle degrees on pipes and corners. It is one of our most popular and versatile files. Its uses stretch from corrosion removal and all the way up to bolt removal/bolt cutting. These rotating file can be used in conjunction with our straight grinder model FG-2XV-50 or our angle die grinder model FCD-6X-51. This rotating file can only be used together with either of the mentioned tools as it is part of a System that has been Classified as COLD WORK and CERTIFIED for use in Explosive Environments by DNV. While this tool does not require water to retain its certification, we have developed a clever mechanism in case water is desired by the Operator or HSSE Personnel, for either tool the cooling cap A-0062 will work.
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.

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.
Depending on the grinding burr or grinding disc you use, the Surface Roughness Profile you can expect goes in the 40-75 microns (2.5 mils) range and achieve +1,600 psi on Pull Test. You can see more details in the comparative table above. Our tools are ideal for corrosion removal and spot repair. Corrosion never sleeps, you need a tool to match it without waiting for your assets to deteriorate completely. Depending on the job size, select the applicable number of tools or suitcases.
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.
