drill bit speeds in drill press

[fread]

fread here, first timer.  does anyone know at what speeds the different wood bits work best in a drill press?

[NCPaladin]

It varies by the type of wood and the type of bit.
Here is a link to suggested speeds for most major bit styles.

My drill press has a chart on the inside for both wood and metal. Other than that, bigger = slower, and smaller = faster. Make sure they are sharp. If you are setting off the smoke alarm, probably dull...

There's a science behind it. Type of material your drilling- soft wood, hard wood, standard metal, hard metal, tempered metal, brass, aluminum, copper, bit size, bit type, bit material. You can find online charts.

My large DP is set around 800 rpm for most uses. The small drill press I use small bits on is set at 2,000 rpm for most uses.

fread here, thank you

My drill press has a dozen or so speeds by changing which shives on the pulleys the belt rides on. It has been on the slowest for several years now. Too much trouble to change it for a few holes.

First

A most hearty welcome and really hope you stick around and show us what you are doing.

One other thing about drilling wood is make sure you eject the chips often or the blank can break due to heat or expansion of the chips inside the flutes of the bit.  I usually drill an inch and bring up the bit and clear the wood and maybe even more in bigger bits.
Last before you go thru the end maybe either reverse the blank or make the blank bigger so it does not blow a big hole out the back side.
