🔧 What it does & how to use

A broach is a tapered, multi-sided cutting tool used by clockmakers and watchmakers to enlarge or smooth out a hole by hand. Simply insert the narrow tip of the broach into the hole and gently rotate it, applying light pressure — the taper gradually reams out the hole to the exact size needed, whether you're fitting a new bush, freeing up a worn pivot hole, or adjusting a hole for a screw or pin. This set of 10 covers a range of sizes from approx 0.7mm up to 3mm, so you can step up gradually through sizes for a clean, controlled fit rather than removing too much material in one go. A must-have for any clock repair bench, useful for both hobbyists and professional clockmakers.
