Template:Broaches Buyers Guide
From DT Online
- If a suitable section of Tool Steel is not available, Broaches for the small-scale work most common in Design and Technology, can be made by grinding teeth profiles into the shortened length of an old file for example (ideally, first Anneal the old file and re-shape it then re-harden and temper to ensure the finished Broach is not too Brittle).
Safety Point! If making from an old file, use a short length, grind a chamfer around the striking end, apply only light taps to reduce the risk of pieces breaking off, and always wear eye protection.
