The Faithfull Conical Rotary Rasp is an essential tool designed for metalworkers and DIY enthusiasts who need to enlarge holes or shape non-ferrous sheet metal with precision. Engineered for use with standard electric drills, it provides a reliable and consistent way to modify sheet metal components, though users should note it is specifically intended for non-ferrous materials and requires steady hand control during operation.

No, this tool is designed exclusively for non-ferrous metals like aluminum, copper, and brass. Using it on harder metals like steel will quickly dull the rasp.
It is generally recommended to use a medium speed to maintain control and prevent the tool from grabbing or jumping.
While it may work on soft wood, it is optimized for sheet metal and will likely clog very quickly when used on timber.
Due to the nature of the hardened steel teeth, it is generally not practical to sharpen these at home once they wear out.
The 6mm shank is a standard size that fits almost all modern electric drill chucks.
Ensure the chuck is fully tightened and the shank is inserted deep enough into the jaws.
The rasp teeth may be clogged with debris; clean the surface with a stiff wire brush.
Verify that the rasp is securely centered in the drill chuck and not bent; check that you are not applying too much lateral pressure.
To set up the rasp, simply insert the 6mm shank into your drill's chuck and tighten firmly to ensure it does not slip during operation. This tool is compatible with any standard corded or cordless drill. To maintain the tool's performance, avoid applying excessive pressure, which can clog the rasp teeth with metal shavings. After use, clean the rasp with a wire brush to remove debris from between the teeth and store it in a dry environment to prevent corrosion. Always wear safety goggles when using this tool to protect against flying metal particles.
