Frequently asked questions
What machine are these knives for?
They are original Bernardo spare parts for the HS 500, a lever shear with a long blade.
The HS 500 has sheet metal capacity up to 0.8 mm (400 N/mm²), length 500 mm, and is intended for artisanal workshops and small laboratories. Return spring and base included, for processing long sheet metal.
What does the HS 500 cut?
The HS 500 is a long-bladed lever shear that cuts sheet metal up to 0.8 mm (400 N/mm²), 500 mm in length.
It is suitable for artisanal workshops and small laboratories. For stainless steel and hardened materials, the nominal capacity may be reduced by 30-40%.
Are the blades made of hardened steel?
Yes, Bernardo blades are made of high-quality hardened and ground steel.
Heat treatment increases surface hardness (typically 58-62 HRC) and resistance to deformation, even when cutting alloy steels or thick aluminum.
How do you know when they need to be replaced?
Signs include burred cuts, sheet edge deformation, altered noise, excessive effort during operation.
For occasional use (hobby, maintenance), the knives last many years. For daily workshop use, a revision every 6-12 months and preventive replacement every 18-24 months are recommended.
How is manual replacement performed?
For manual shears and notchers, replacement can be performed by the operator: removing fastening screws, disassembling the old knife, mounting the new one with the correct tightening torque.
Important: respect the tightening torque indicated in the manual (typically 30-60 Nm). Insufficient tightening can cause the knife to move, while excessive tightening risks cracking it. Krollit provides technical documentation.
