Marking Out and Drilling Practicals
In a fitting shop, students mark out a mild steel plate before they drill it. They scribe the centre lines with a Scriber run along a Steel Rule, then rest the punch point where the lines cross. One light tap shows whether the dot sits on the cross, and a firmer blow then deepens it for the drill.
The punched plate goes on to a drilling exercise on the Drill Press, starting with a small pilot drill. Teachers also show how a punch dot gives the leg of a Wing Divider a firm seat when students scribe a circle round a hole centre.
Frequently Asked Questions
What is the difference between a centre punch and a prick punch?
A prick punch has a slimmer, sharper point and makes a light mark for layout lines. A centre punch has a blunter point and makes a wider, deeper dent that guides the tip of a drill. Many fitters prick the mark first, then enlarge it with the centre punch.
Why punch a mark before drilling?
A twist drill has a chisel edge at its tip that tends to skid on smooth, flat metal. The punched dent holds the drill point in place as it starts, so the hole begins where the lines cross.
Which hammer should be used with a centre punch?
A light ball peen or engineer’s hammer suits it. Hold the punch upright and strike its head squarely with one firm blow. Too heavy a blow on thin sheet can dent or bend the metal around the mark.
How is a blunt point restored?
Grind the point on a bench grinder while turning the punch, so the cone stays even and centred. Dip it in water often so the tip does not overheat and soften.
