Examples of Pillar Drill usage
In my experience, i have used the pillar drill a number of times. During my second year at university, i manufactured a sliding bevel.
There were certain holes needed to be cut in a metal piece to make my sliding bevel.
Definition as seen in www.wikipedia.com: A pilot hole is a smaller hole drilled into a material prior to a larger hole being drilled, widening the hole to the desired width. Drilling a pilot hole prevents a larger drill bit from slipping on the material - a potential safety hazard, as well as an increased likelihood of the work being damaged.

- Once i completed this, i had to choose what size of diameter of drill bit to use.
- I fitted the drill bit into the chuck (taking into account all of the safety precautions)
- I was then able to use the drill carefully and correctly.
