Who uses the HBS 210 Vario PRO and for what
The Bernardo HBS 210 Vario PRO is a horizontal bandsaw for professional use, designed for mechanical workshops, metalworking shops, blacksmiths, and industrial maintenance requiring precise cuts on metal materials. A key construction feature: the continuously variable cutting speed from 0-90 m/min allows for selecting the optimal value for each material (mild steels 60-80 m/min, stainless steels 30-50 m/min, hard materials 20-30 m/min, tool steel 15-25 m/min). Correct speed adjustment significantly extends the life of the bimetallic blade and improves cutting quality. The cast iron vice with quick-release secures the workpiece in precise position without the need for wrenches (quick change between different workpieces). The workpiece stop allows for repetitive cuts of the same length for series production. Continuously adjustable lowering with hydraulic cylinders and an adjustable valve allows control of cutting pressure based on the material: low pressure for hard materials (to prevent blade breakage), high pressure for soft materials (for higher cutting speed). The automatic limit switch stops the machine at the end of the cut, preventing the blade from continuing to run idle and causing unnecessary wear. In Krollit customer workshops, the HBS 210 Vario PRO is chosen by mechanical workshops with regular cuts on round and square bars, metalworking shops for profile cuts, blacksmiths for tubular cuts, and industrial maintenance personnel for component preparation.
Its place in the Bernardo range
The Bernardo metal bandsaw range is organized by maximum workpiece size (cutting capacity) and drive type. The HBS 210 Vario PRO is in the mid-range: Ø 170 mm capacity on round stock at 90°, 1.5 kW 230V single-phase motor (compatible with any industrial civil outlet), variable speed 0-90 m/min. For workshops with smaller workpieces (Ø below 130 mm), more economical models from the compact range are available; for workshops with larger workpieces (Ø above 200 mm), heavy-duty models with 400V three-phase motors and higher cutting capacities are available. The 'Vario PRO' feature indicates the professional category with electronic variable speed: the standard 'PRO' version without Vario has fixed speed, which is less expensive but less flexible for different materials. For workshops with a variety of materials (mild steels, stainless steel, tool steel), the Vario version is the correct choice; for workshops specializing in a single material, the standard version is more economical.

45° angled cutting capacity (Ø 125 mm on round stock, 95×95 mm on square stock) for custom cuts on welded structures. Hydraulic cylinders for adjustable cutting pressure. |
Not suitable for: cutting materials over Ø 170 mm on round stock or 150×150 mm on square stock (the machine has limited capacity; larger bandsaws in the range are properly sized for larger workpieces); environments without a 230V single-phase power supply with an adequate line (15-20A); heavy industrial applications with continuous cutting cycles (for continuous intensive use, semi-automatic or automatic bandsaws with automatic loading are properly sized); workshops requiring CNC cutting (HBS machines are manual; dedicated CNC saws are needed for automatic programmed cutting).

Frequently asked questions
Which cutting speed should be chosen for each material?
Guidelines for cutting speeds: mild steels (Fe360, S235) 60-80 m/min; alloy steels (C45, 39NiCrMo3) 40-60 m/min; stainless steels (AISI 304, 316) 30-50 m/min; hard materials (hardened steels HRC 40-50) 20-30 m/min; tool steels (HSS, M2, D2) 15-25 m/min; aluminum and light alloys 80-90 m/min; brass and bronze 60-80 m/min.
Optimal speed also depends on: workpiece diameter/section (large diameters require slightly lower speeds), type of bimetallic blade (blades with positive teeth tolerate higher speeds), cooling (higher speeds are possible with coolant). For series production with recurring materials, it is recommended to record optimal speeds on a work sheet for future reference.
Can I cut stainless steel with this machine?
Yes. The HBS 210 Vario PRO is specifically designed for cutting stainless steels: the variable speed allows selection of the optimal 30-50 m/min for AISI 304 and 316 stainless steel, the adjustable cutting pressure via hydraulic cylinder prevents tooth stripping typical of stainless steel cutting, and the integrated cooling system dissipates heat, preventing material hardening.
For effective stainless steel cutting, it is recommended to use specific bimetallic blades for stainless steel (e.g., M42 with 4-6 teeth per inch) and appropriate coolant (specific oil-water emulsion for stainless steel or neat oil for metalworking). Standard blades supplied are suitable for mild steels; for stainless steel, purchasing dedicated blades is recommended. Original Bernardo stainless steel blades available from stock with 3-5 business days shipping.
How long does a bimetallic blade last?
In daily professional use, an original bimetallic blade typically lasts 100-300 hours of actual cutting time (excluding stops and setup). Variability depends on: material cut (mild steels longer life, stainless steel medium life, hard materials shorter life), correct cutting speed (incorrect = accelerated wear), adequate cooling, blade quality.
To optimize blade life: adhere to recommended speeds for the material, keep the coolant active during cutting, check blade tension (integrated manometer), replace the blade when a reduction in cutting quality is observed (burrs, non-straight cut, vibrations). A new blade allows for clean and fast cuts; a worn blade requires more time, lower quality, and can break, causing safety risks.
Is the 230V single-phase power supply really sufficient for professional use?
For the HBS 210 Vario PRO, yes. The 1.5 kW S1 100% motor with start-up managed by power electronics is dimensioned for continuous use at 230V single-phase. Startup is managed gradually (soft start) to prevent the circuit breaker from tripping on civil meters of 3-4.5 kW.
Recommended check before installation: electrical line with adequate cross-section (minimum 2.5 mm² cable for sections up to 20 m, 4 mm² for over 20 m), dedicated 16A miniature circuit breaker, industrial CEE 16A 230V socket (preferable over a 'Schuko' civil socket for professional use). For workshops without an adequate line, electrical upgrading is necessary (typical cost €200-500 including electrician's work). For workshops with other simultaneous loads (compressors, extractors), check the available power on the meter.
Does the coolant need to be refilled periodically?
Yes. The integrated cooling system with a 100 W pump uses an oil-water emulsion (typically 5-10% of specific metalworking oil in water). The tank level should be checked periodically (every 20-50 hours of operation depending on intensity) and topped up with the same initial concentration.
For intensive use with frequent cuts, the coolant fluid is depleted by evaporation (water) and contamination (chips, dust). Complete fluid replacement is recommended every 6-12 months: drain old fluid, clean the tank, refill with fresh emulsion. Specific oil for emulsion (concentrate) available from standard industrial suppliers. For hard water (areas with high lime content), using decalcified or demineralized water is recommended to prevent scale buildup in the system.
