Best Drill Speed


Recommended Posts

I have a drill bit that is perfect for some bridge studs. About 15/32" I believe.

The drill press is running slow today.

What is the best speed for accuracy?

Fast or slower? The wood is maple and mahogany.

Depends on bit diameter, and bit type. Fast enough to cut and clear wood shavings, not so fast as to burn. If there's smoke, it's either too fast, or you're feeding too fast, pushing too hard, or not letting the chips clear enough. I think routerbits.com has a bit on appropriate bit speeds for various forstners (hint: slower than you think), but it may have been some other locale....

hmm... interesting question. I tend to leave mine set at about 800 rpm unless I'm sanding or safe-t-planing.
