The conduit tube sheet metal perforators with inch bearings are specifically designed to meet the demands of the American market.
These mechanical punches, equipped with unground bearings, are high-precision tools capable of punching steel sheets up to 2 mm thick and stainless steel sheets up to 1.5 mm.
The inclusion of a bearing in its design significantly improves the performance of the tool, allowing a 50% reduction in the force required to make cuts, making it an ideal option for creating large diameter holes.
These perforators are manufactured with series 55 screws, recognized for their very high resistance of 140Kg/mm2, which guarantees durability and effectiveness even in the most demanding applications.
Although they are capable of drilling a variety of steels and stainless steels, it is essential to adjust their use to the specifications of each material to optimize results.
Additionally, it is advisable to apply oil to the sheet before making the cut to prolong the life of the tool and ensure clean cuts.

Recommendations for use
Oil the sheet metal well before drilling to reduce friction and prolong tool life.
Ensure that the material to be drilled is firmly supported to avoid movement during operation that could cause errors or damage.
Do not exceed the recommended thickness limits (2 mm for steel and 1.5 mm for stainless steel) to avoid damaging the tool.
Use the 56 series if in doubt about the material to be drilled, as it is designed to handle a variety of materials safely.
Perform cuts in a well-ventilated area to avoid inhalation of metal particles and ensure a safe working environment.

Maintenance recommendations
Clean the punches after each use to remove metal debris that may affect their performance in future cuts.
Regularly check and lubricate bearings to ensure smooth operation and extend tool life.
Store the drills in a dry and clean place to avoid corrosion of the metal parts and keep the tool in optimal condition.
