Frequently asked questions
Which machine are these knives for?
They are original Bernardo spare parts for the HS 8, a compact lever shear.
The HS 8 has sheet metal capacity up to 4 mm (400 N/mm²), length 190 mm, round bars Ø 13 mm, flat bars 70x5 mm, and is intended for blacksmiths, installers, and training workshops. Blade 205 mm, optimized geometry to reduce effort.
What does the HS 8 cut?
The HS 8 is a compact lever shear that cuts sheet metal up to 4 mm (400 N/mm²), length 190 mm, round bars Ø 13 mm, flat bars 70x5 mm.
It is suitable for blacksmiths, installers, and training workshops. 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 burr cutting, deformation of the sheet metal edge, altered noise, and excessive effort during operation.
For occasional use (hobby, maintenance), the knives last many years. For daily workshop use, 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: remove fixing screws, disassemble the old knife, assemble the new one with the correct tightening torque.
Important: observe the tightening torque indicated in the manual (typically 30-60 Nm). Insufficient tightening causes the knife to move, excessive tightening risks cracking it. Krollit provides technical documentation.
