The 55 Series Mechanical Round Sheet Metal Punch Set of 4 is a high precision tool designed to cut sheet metal up to 2mm thick on common steels and up to 1.5mm on stainless steels.
This kit includes drills equipped with bearings, which significantly increases their performance, reducing the force needed to make the cut by 50%, making them ideal for drilling large diameter holes.
The screws of these perforators are of exceptional resistance, with a capacity of 140 Kg/mm², which guarantees durability and reliability even in intensive work conditions.
The edge of the punches has been ground, providing a clean and precise cut, as well as extending the life of the tool.

Recommendations for use:
Before using the hole punches, be sure to clean and oil the sheet metal well to make cutting easier and prolong the life of the tool.
Wear eye protection and gloves during use to avoid accidents and protect yourself from metal fragments.
Select the appropriate punch for the thickness and type of material to be punched.
Carry out the cut in a controlled manner, applying constant force and avoiding sudden movements to obtain an optimal result.
When working with stainless steel sheets, consider using the 56 series if you are in doubt about the punch's capacity.

Maintenance recommendations:
After each use, clean the perforators to remove metal and oil residue, thus avoiding corrosion.
Sharpen the edges of the punches periodically to maintain their cutting efficiency.
Store punches in their original case in a dry, safe place to protect them from wear and moisture.
