💡 Why is an annular cutter chosen over a conventional twist bit for magnetic surface drilling?
The core drill design strips out less material so your magnetic base unit pushes through thick plate faster.
- Precision ground cutting edges slice cleanly without pre drilling steps or leaving rough burr marks.
- Tough hss geometry stays handy for re sharpening through repeated passes on bridges, ships, and structural frames.
- Proper oil lubrication paired with steady feed rates protects the bearing housing during heavy production runs.
