A center punch is used for marking an "indent" before a hole is bored with a drilling machine. The point is usually set to the point of intersection between two marking line. Generally, the marking process is done on a flat table, called a marking-off table.

What is used to mark the location of a hole to be drilled?
Use a thumbtack to poke a hole through the center of the mounting hole or a pen to mark the area. Let the tape be your guide. Remove the tape and place it on the wall where you want to mount your power strip. Now you can drill the screws directly into the marked area on the tape.
What is used to mark the Centre of a hole before drilling?
It is usually used to mark the center of a hole when drilling holes. A drill has the tendency to "wander" if it does not start in a recess. A center punch forms a large enough dimple to "guide" the tip of the drill. The tip of a center punch has an angle between 60 and 90 degrees.
Why is the position of the Centre of a hole punch marked before drilling?
The location of this hole is marked and the punch is placed into this location and the punch is hit ONCE with the hammer to make a small dent. This dent in the metal will allow the drill bit to be located and the hole should be drillen in the correct place.
How do you mark a pilot hole?
Mark the spot with pencil or tape before you begin.
Mark the spot in pencil. Or, better yet, create an “X” with painter's tape over the location for your nail or screw. The tape will reinforce the wood and offer extra protection against possible cracking.
How do you properly drill a blind hole?
In order to make a blind drill hole to accurate depth, a drill press with a depth stop device is needed. Or, in NC machining, the programming will stop the bit at the correct depth.
Is used for marking the material before drilling?
A center punch is used for marking an "indent" before a hole is bored with a drilling machine. The point is usually set to the point of intersection between two marking line. Generally, the marking process is done on a flat table, called a marking-off table.
How does a Centre punch work?
A spring-loaded center punch is used by pressing the marking end against the work piece. A spring-loaded center punch stores energy in a spring, and as compressed it is triggered and releases the spring-stored-energy as an impulse that drives the punch into the work surface, producing the dimple, character, or symbol.
What is a Centre punch for?
Definition of center punch
: a hand punch consisting of a short steel bar with a hardened conical point at one end used for marking the centers of holes to be drilled.
Why is it important to use apply center punch before boring holes in a piece of metal?
A center punch is a tool with a pointed end that makes a dimple in your piece of material right where you intend to drill a hole. - When you begin drilling, the recess of the dimple relieves pressure from the flat tip of the bit (the "chisel tip" or the "web".) This prevents bending, chipping, breaking.
