Workshop Exercises with the Round File
In pipe work, students hold a length of pipe in a Pipe Vice and cut it with a Hacksaw. They then file away the burr inside the cut end, so the bore is clear before a fitting goes on. The round file also opens a drilled hole to a larger size when no drill of that size is at hand.
In woodwork and plastics projects, the same file smooths curved details and holes, such as a cable slot or a round opening in a box side. Teachers can set it beside a double cut flat file to show how single cut teeth leave a finer surface.
Frequently Asked Questions
What jobs is a round file used for?
It is used for filing inner pipe walls, enlarging round holes, rounding the ends of slots and smoothing curved details in wood or plastic. On metal it follows a hacksaw or drill to bring a hole or bore to its final shape.
What does single cut mean on this file?
The teeth run in one direction as parallel rows. A single cut file needs less pressure and leaves a smoother surface than a double cut file, which suits finishing inside holes and filing softer materials.
How do I file a hole round without making it oval?
Turn the file a little on each forward stroke and work evenly around the hole rather than in one place. Check the hole often, and stop just short of the line before the last light strokes.
What is the hole in the handle for?
It lets the file hang from a pegboard hook. The file then stays in sight on the tool board, and its teeth do not rub against other tools in a drawer.
Is this file the same as the half round file?
No. Both are 300 mm long in Cut 1, but this file is fully round for small holes and pipe bores. The Half Round File has one rounded and one flat face for larger curves and flat surfaces.
