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".
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.
Speeds and Feeds
- Steel
- Aluminium
- Soft Wood
- Hard Wood
Safety
- Never leave the key in the chuck 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 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.
