Drill large holes by predrilling a hole matching the diameter of the web of the drill bit.
Choose the correct speed for the size hole and the material being drilled.
When in doubt use slow speeds and strong feeds.
Smaller holes require quicker speeds and lighter feeds.
Back holes in soft materials with another piece of material to prevent "Blowout".
Seting up a drill press
There shold be only the smallest amount of play when trying to move the chuck back and forth by hand.
Make sure when drilling through work that the drill bit can not come in contact with the table.
Use a piece of 1/2" drill rod in the chuck with a square to measure the table for squareness.
Setup holes so the minimum amount of quill extention is required for drilling a hole.
