Who uses the HPS 55 and for what
The Bernardo HPS 55 is a 55-ton hydraulic punch and shear machine: it is positioned between the HPS 45 (45T, 12 mm) and the HPS 60 (60T, 16 mm) for thicknesses up to 15 mm. It combines three functions in one machine: punching holes in flat bars and profiles, cutting flat steel bars up to 15 mm × 330 mm, and cutting angle profiles up to 120 × 120 × 12 mm. With 8 strokes per minute, it is oriented towards artisan-professional production. In Krollit's customers' workshops, it is used by blacksmiths, structural metalworkers, and construction companies that work with standard structural steel.

55T for thicknesses up to 15 mm: covers artisanal structural metalworking with three functions in one machine. |
| Intense industrial production |
Adequate |
For high volumes or thicknesses over 15 mm, consider the HPS 60 (60T, 16 mm) or HPS 90 (90T, 20 mm). |
Not suitable for: thicknesses greater than 15 mm (consider HPS 60); high-strength steels without technical verification; non-professional use.

Frequently asked questions
What is the difference between HPS 45, HPS 55, HPS 60 and HPS 90?
HPS 45: 45T, 12 mm, standard Ø 22 mm. HPS 55: 55T, 15 mm, standard Ø 24 mm. HPS 60: 60T, 16 mm, standard Ø 25 mm. HPS 90: 90T, 20 mm, standard Ø 30 mm. The HPS 55 is the intermediate model between the 45 and 60: for those who regularly work with thicknesses between 12 and 15 mm where the HPS 45 is not sufficient but the HPS 60 would be oversized.
Can the HPS 55 punch stainless steel?
Yes, with reduced capacity. On AISI 304 stainless steel (600 N/mm²), the capacity is reduced by 30–40%: effective thickness approximately 9–10 mm. Check with Krollit for specific high-strength materials.
Are the punches and dies interchangeable?
Yes. The HPS 55 uses interchangeable punches and dies from standard Ø 24 mm up to optional Ø 40 mm. Sets of original Bernardo spare punches and dies available with 3–5 business days shipping.
Is a special foundation required?
HPS punch and shear machines generally do not require a special foundation on standard industrial flooring (15–20 cm concrete). Contact Krollit for the weight and anchoring specifications of the HPS 55.
Is assistance and spare parts available?
Customer support in Italian available. Original Bernardo spare parts (punches, dies, gaskets) with 3–5 business days shipping.
