My boss wanted to try to reuse the redwood siding we were taking off his house to make some upgrades. Prying at the boards caused splitting, so we decided to use a hole saw to separate the nails from the wood. The local home center had a 3/8-in. diamond hole saw for tilework that turned out to be the perfect thing. The bit’s diamond grit works fast and creates a smooth cut.

To start the cut, position the bit over the nail at a slight angle and start the bit rotating slowly. Once the kerf is established, straighten the bit and drill to a depth of 3/4 in., leaving the nail and cutting the siding around it. Once you’ve drilled around all the nails, make a few passes with a utility knife along the painted joint between boards so they pop free. When it was time to reinstall the siding, I plugged the holes with 3/8-in. redwood plugs that I cut on the drill press. I glued them in the holes and then sanded them flush. The reclaimed siding cost next to nothing and matched perfectly.
