There are a lot of options for using a tool for cutting hardboard. It all depends on the amount of work. The most common means of processing such material are electric circular saws, jigsaws, hacksaws. If an even cut is not needed, even scissors are used to cut metal. True, the hardboard breaks and breaks when exposed.

The use of a jigsaw is convenient for any amount of work. To obtain the best quality cut with smooth edges, use a file with small teeth. The best option would be to use a file for cutting metal. Due to the weak wiring of the teeth, the seam is thin, but its edges do not tear and remain flat. For the convenience of work and getting an even seam, the hardboard should be laid and pressed firmly to a flat surface. For example, to a countertop or workbench. This will prevent the sheet from vibrating. To achieve the best quality, the edges of the cut piece are treated with fine sandpaper.

When processing hardboard with a hand circular saw, experienced craftsmen use a circle on a tree from a grinder. Suitable size can be found in the store. A conventional wood saw blade has large teeth, and this will result in tears at the edge of the seam. As with a jigsaw, cutting with a circular saw must be carried out on a flat surface, tightly pressing a sheet of hardboard to it. The edges of the cut are sanded with sandpaper.

In the absence of an electric tool and with small volumes, the hardboard can be cut with a hand hacksaw with small teeth. Some use a hacksaw for these purposes. As with other tools, you need to cut the hardboard on a flat table. The cutting edge of the hacksaw should be kept parallel to the surface of the sheet. The edges will receive less damage and will not require a long finish.

Sometimes, in conditions of urgency, they resort to the most barbaric method of processing hardboard - cutting it with scissors for metal. With this method, do not press the hardboard to the table. Cutting can also be carried out on weight. The edges of the part cut off with scissors will have to be leveled for a long time using a rasp and sandpaper.
