Dot Punch
Description
A Dot Punch is a hand tool used for marking small indentations on metal surfaces, typically to locate layout points or guide further machining operations. It has a sharper point compared to a center punch, allowing finer and more precise marking. This tool is widely used in fitting and metalworking for layout work.
Uses
- Marking layout lines and reference points.
- Making light indentations on metal surfaces.
- Guiding drilling and machining operations.
- Used in fitting and workshop marking work.
- Precision marking tasks.
