Workshop Practice with Round Files

A common fitting exercise starts with a hole drilled on a Drill Press. The hole is then opened out with a round file until a pin or round bar just slides in. Students learn to roll the file a little on each push stroke so the hole stays round, and to file from both sides of the plate.

Round files also deburr the inside of pipe ends cut with a Hacksaw, with the pipe held in a Pipe Vice. In slot work, the straight sides are filed flat first and the round file then shapes the curved ends.

Frequently Asked Questions

How do I choose the size of round file for a hole?
Pick a file whose diameter is clearly smaller than the hole, so it moves freely and cuts on one side at a time. Short files such as the 4 in and 6 in suit small holes in thin parts. The 10 in to 14 in files suit bigger bores and pipe ends.

Which grade of cut should I start with?
Start with the rough (bastard) grade when a lot of metal has to come out. Change to medium as you near the size, and finish with smooth for a clean bore. Roughing with a smooth file wastes time and clogs its teeth.

What is a rat-tail file?
It is a common workshop name for a small, slender round file, named for its shape. It does the same jobs on a small scale: opening holes, cleaning out slots and smoothing tight curves.

Can a round file be used on wood or plastic?
Yes. It shapes holes and curves in wood, plastic and soft metals as well as steel. Use light pressure on soft materials and clean the teeth often, as plastic and aluminium clog a file quickly.
