Over here I’ve successfully drilled at least 30 pots with diamond hole saws, for drainage and for wiring. Having drain holes out in the Incersion area of Puget sound is a real plus.
I started out using the putty dam after reading
@River's Edge post on this method. However over time I went two other ways to lubricate the bit. This method is straightforward and used for pots with trees inside. I only use it in the case I don’t want to pull the tree out. I have another person with a spray bottle constantly spray the drill sit while I drill.
The second method is my own. One takes a tub of water, then places chocks of wood directly inside the pot where drilling through for internal support. Then flip the pot over and position it underwater so it’s submerged 1/4-1/2”. Tilt the bit to score the pot when first drilling. Then shift the bit to 90” degrees on the pot surface.
Only cautions is that one should use a battery powered drill and easy pressure in the final stages of drilling so as not to blow out the interior part of the pot.
Ok, this is a hot button issue so I’m gonna go up on the proverbial soapbox, so please skip this part if you so desire. It’s also a bit of a birdwalk, so I apologize in advance to
@One First Matter All
While I would drill any pot with poor drainage with confidence, even expensive ones, I’m absolutely not a pot aficionado (in either meaning of the phase). I feel buying an expensive, or ancient, pot that looks good with poor drainage is just a waste of money. Others my differ or even try to compensate with a large drain layer... not a long term solution imho.
As an alternate means to avoid drilling to assure drainage, my purchases are restricted to pots with large drain holes and decent side wire/drain holes.…. with no pooling on the bottom of the pot caused by poor design/firing. (I learned this the hard way in just three years - slow learner

). This often means buying newer pots. In fact this design criteria has been suggested to a number of potters in the last year.
I’ve done a couple commissions lately. Each has drainage criteria specified. Luckily a good number of potters like Vicki Chamberlien, Matt Borst and
@sorce are well on top of these design feature.
Ok, I‘m done. thanks for your forbearance!
cheers
