I'm planning to drill 150 clean holes for 9/16" steel railing balusters in white oak flooring. These holes will be epoxied or glued in place without any trim rings, so I'm looking for the best drill bit and technique to achieve a precise finish. Any expert advice?

If you can, use a plunge router with a spiral downcut bit. It really helps with making clean cuts. Just remember to take it slow for the best results!
Pro tip: Before you start drilling, put down a few layers of masking tape. This helps with layout and keeps the edges of the holes crisp! It's a game-changer.
Using a drill press or a portable drilling guide to keep the drill bit perfectly vertical is key. A Forstner bit can make super clean holes, but be aware that it may not hold up well to 150 holes, especially at 9/16". It works better than freehand, though!
Definitely go for a Forstner bit with a mag-base drill. It makes straight holes and saves your arms from fatigue. I recommend replacing the bit every 50 holes if you want to maintain quality!
For me, Forstner bits are the best for clean holes. You're right about keeping the bit sharp, so make sure to have a good quality one and sharpen it as needed. You might consider how many holes you expect to get through before it needs sharpening, especially if you're using top brands like Whiteside.
Yeah, I agree! A mortising bit on a plunge router sounds like the way to go.
