Pillar drill is a large version of normal drill and it has a long column which normally stands on the floor or can be mounted on a table. Because of its larger size it is capable of being used to drill larger pieces of materials and produce larger holes. A pillar drill consists of the following parts (numbered as shown in the diagram)
1) Locking Lever which prevents the lowering of the drill assembly.
2) Chuck which is a holding device for the drill bit.
3) Safety guard.
4) Work Table.
5) Work table lock which holds the table in position when the height has been selected.
6) Pillar which is the column.
7) Lowering handles which rotate to lower the chuck assembly.
8) Pulley Gearing.
Special care and consideration must be taken into account when working on a considerable large machine like Pillar drill. Each bit of work has a risk attached to it. Proper understanding of working of each part and the understanding of work we are going to do in the drill is important. Below are the list of safety steps to follow when using the pillar drill.
1) Always use the safety guard.
2) Must wear goggles when drilling materials.
3) Clamp the material down properly or using the machine vice.
4) Never hold materials by hand when drilling.
5) Always allow the chippings to clear the drill by drilling a small amount at a time.
6) Listen and follow all the teachers instructions.
7) Always make sure that you are well aware of the emergency stop button in place if something goes wrong.
8) Don’t ever panic when using the drill.
