EASY TO USE
Center pilot drill bits are for wood, metal, etc.;
Here is how you can keep the drill bit on target:
1. You can make your own guide out of plywood - plastic or even cardboard. All you need is to keep the drill bit in place until it makes the initial marks.
2. You can start drilling at an angle, with the edge of the drill bit making a C slot and then getting the drill bit up to vertical.
3. You can manually guide the drill bit with a wet sponge.
Please use protective gear.
