==Drilling a hole in a drill press==
*Layout the position of a hole with a scribe. *Mark the exact hole position with a punch. *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".
==Setting Seting up a drill press== *There should 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 extension extention is required for drilling a hole.
==Speeds and Feeds== *Steel *Aluminium *Soft Wood
*Hard Wood
==Safety== *Never leave the key in the chuck while wihile changing drill bits. *Never wear gloves while holding work in a drill press. *Always try to hold down work by bolting it to the table or by using a vise. *Always use usy eye protection when using a drill press. *Unplug or remove the dafety key when chaning drill bits.
*Never allow the chip fromed by drilling a hole to grow larger than 1 inch. If the chip starts to become a string relax pressure on the feed until the chip breaks off.
