Drill Press RPMs

[aggie182]

How many RPMs do you run when you drill wood blanks? How about acrylic?

I got a drill press today and set it on 1600 RPMs. I'm thinking this is too fast from the squeal and temp of the wood shavings.

Thanks in advance.

Here"s some pics of WOOD magazines drill press speed chart.Don't know if you'll find it helpful of if others would agree but I'll share it anyway.

don't agree:biggrin:

One thing you have to remember it is a pen blank you are drilling and drill into end grain so to me those charts are useless for what we do. My opinion only.

I drill pen blanks on the lathe, at less than 500. If you want to take a chance on cracking a blank or having a wood blank warp on you, then drill faster.

Third chart instructs to "reduce speed when drilling in end grain."
