Frequently asked questions
Which machine are these knives for?
They are original Bernardo spare parts for the HS 12, a compact lever shear.
The HS 12 has sheet metal capacity up to 4 mm, length 265 mm, rounds Ø 13 mm, flats 70x5 mm and is intended for craft workshops, blacksmiths, construction sites. 300 mm blade, ergonomic lever for minimal effort.
What does the HS 12 cut?
The HS 12 is a compact lever shear that cuts sheet metal up to 4 mm, length 265 mm, rounds Ø 13 mm, flats 70x5 mm.
It is suitable for craft workshops, blacksmiths, construction sites. On stainless steel and hardened materials, the nominal capacity may decrease 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, deformation of the sheet edge, altered noise, excessive effort during operation.
For occasional use (hobby, maintenance), the knives last many years. For daily use in the workshop, an overhaul every 6-12 months and preventive replacement every 18-24 months is recommended.
How is the replacement performed manually?
For manual shears and notchers, replacement can be performed by the operator: removal of fastening screws, disassembly of the old knife, assembly of 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.
