A slate and punch cutter is a hand tool designed for cutting and punching holes into roof slates and man-made tiles.
There are different brands of slate and punch cutter, but they all perform the same function, so it is personal preference as to which one to use.
When it comes time to replace a broken or damaged roof slate, you could use a slate and punch cutter to trim the slate to the right size and shape for your roof.
The tool is then used to punch a hole in the slate so it is ready to hang on the roof.
