💡 What maintenance routine keeps a manual conduit hole cutter handy through heavy daily use?
Keep the faces slick with light oil so they slide right in without sticking.
- Set the punch square and crank it steady to prevent off center scoring
- Withdraw the scrap ring often to kill friction heat and protect the edges
- Rotate the pilot tip regularly to keep concentric cuts dead straight
- Wipe the frame dry after jobsite dust stops premature rust dead in its tracks
