The punch can be hardened and tempered using the same technique as used for the chisel. The two-heat method is a useful alternative. Heat about 20 mm of the punch, including the point, to just above dull red heat and quench the whole tool in water. Next, clean and polish the point of the punch.
Can you punch stainless steel?
Which metals can be punched? Thank to the evolution of sheet metal punching, of machines and know-how, almost all metals can be punched: iron punching, stainless steel punching, aluminum punching, copper punching, brass and special alloys punching.
How do you make steel harder but not brittle?
To make steel harder, it must be heated to very high temperatures. The final result of exactly how hard the steel becomes depends on the amount of carbon present in the metal. Only steel that is high in carbon can be hardened and tempered.
What is a brass punch used for?
Brass-head hammer and punches are ideal to use where sparks from ferrous metals would be hazardous, or where precision metal parts could be damaged by steel tools.

How do I choose the right tool steel for my punch?
However, tool steel selection is largely dependent on individual preference and application requirements.The success of a perforating punch is largely dependent on two key criteria: Structural soundness. When it comes to punch performance, other key criteria include the following: strength; load distribution; fatigue-resistance.
