There’s a 1995 PBS Nova episode in their Secrets of Lost Empires series which includes a segment on drilled granite. The episode features egyptologist Mark Lehner, stone mason Roger Hopkins, and ancient tool expert Denys Stocks.
The episode mainly explores the question of how an obelisk was raised. The team ran out of time before they were able to reach a satisfying conclusion, but they returned to Egypt in 1999 to record another NOVA episode, which includes two competing theories on how to raise an obelisk. I highly recommend both episodes.
