Hi all. I'm new to the workshop and would like to know the best tool for cutting through nails on pallets.
Welcome to Workshop @1Learner. We're pleased to have you join us and trust that you'll get loads of inspiration and advice from our helpful members.
You might find these previous posts useful:
A grinder is easiet to cut through a nail assuming you have the right access/angle to it. Have you already removed some of the wood so the nail is exposed?
You should just be able to pull them out with a claw hammer even.
