Trepanning
- Trepanning tools cover a large range of diameters up to 500mm [20 inch].
- The trepanning process is performed on blank material – without any predrilled hole - and leaves a solid core in the middle of the hole rather than removing the entire area in the form of chips.
- Trepanning consumes less power than solid drilling, for the same diameter hole.
- Trepanning in blind hole applications may not be practical due to the difficulty in removing the core.
