Best Drill Speed

[MP63]

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.

Thanks,

Mike

I use about 1550 on everything I drill with, brad point, forstner, or spade style bits all work well with all woods I have drilled into. I don't think going faster than this would be smart for the forstner style bits.

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.

I second Mattia, it really depends on what you are drilling. Here is a really nice chart that covers drill speeds for wood and metal:
