The Preciva 18PCS File Set comes with a nice mix of file cuts, designed for different kinds of tasks. You've got larger files in flat, triangle, half-round, and round shapes, plus some needle files. This variety makes them pretty versatile, especially for materials like aluminum and steel.
Based on our research, these files are made from high carbon steel, so they’re quite durable and handle metal pretty well. It's worth noting, though, that they have a smooth cut, which makes them better for fine-tuning rather than removing lots of material from really hard metals.
You’re not just limited to metals, though. These files can also work on wood and plastics. People have found them helpful for a range of projects, which is nice if you like tackling different materials. They seem to do a good job with aluminum and brass too, making them handy for light mechanical work and hobby projects.
There are some durability concerns, especially if you're going to put them to the test on tough metals a lot. A few folks mentioned that the handles might loosen over time after heavy use.
If you're looking for something for casual DIY projects or lighter jobs, they should work pretty well. Just maybe not as much for intense, professional metalwork.
So, if you're a hobbyist or need something for lighter filing work where precision matters but heavy-duty isn’t the goal, this file set could be a cost-effective pick.
