Bianco 280 Dual Mitre Manual Bandsaw with Variable Blade Speed
The Bianco 280 M-DARV is a manual horizontal bandsaw with hydraulic descent assist, combining Italian precision engineering with dual mitre capability for professional metalworking applications. This machine handles round stock up to 220mm diameter and features variable blade speed control, making it suitable for fabrication shops, engineering workshops, and machine shops cutting both mild steel and stainless steel.
Manufactured by Bianco, an Italian bandsaw specialist with over 30 years of experience, the 280 M-DARV builds on the proven 280 M platform with three key upgrades: hydraulic assisted descent for controlled cutting, dual mitre capability (60° right and 45° left), and a blade speed variator for optimized cutting performance across different materials. The cast bow construction from special alloys ensures rigidity and precision throughout the cutting process.
The hydraulic descent assist system controls the bow's downward movement, allowing you to adjust the descent speed via a control dial. This reduces operator fatigue during extended cutting sessions and provides more consistent cutting pressure compared to manual pull down operation. The dual mitre capability eliminates the need to reposition material when making angled cuts in both directions.
Applications
- Structural fabrication: Cutting I-beams, channels, angle iron, and profiles with mitre cuts for joinery and frame construction
- Custom metal fabrication: Producing architectural metalwork, railings, and structural components requiring precision angle cuts
- Machine shops: Processing round bar, square stock, and tube for mechanical assemblies and component manufacture
- Engineering workshops: Fabricating brackets, supports, and structural elements where dual mitre capability speeds production
- Educational institutions: Teaching metalworking and fabrication techniques on professional-grade equipment
- Maintenance and repair shops: Handling varied cutting requirements across different materials and angles
Key Features & Benefits
- Hydraulic descent assist: Controls the cutting bow's downward movement with adjustable speed. You lift the bow manually, engage the hydraulic lock to hold it in position, then use a control dial to regulate descent speed during cutting. This system reduces operator fatigue and provides consistent cutting pressure.
- Dual mitre capability (60° right and 45° left): Cuts at angles up to 60 degrees right and 45 degrees left. This eliminates material repositioning when making angled cuts in different directions, saving setup time and improving accuracy for structural assemblies and custom fabrication projects.
- Blade speed variator: Provides infinitely variable speed control in addition to the two-speed motor (35 and 70 metres per minute). This allows you to optimize cutting speed for different materials, with slower speeds for stainless steel and faster speeds for mild steel.
- Cast bow construction: From special alloys ensures rigidity and maintains one of the highest precision standards in the Bianco bandsaw range. The cast frame absorbs vibration and maintains blade alignment throughout the cutting process.
- Carbide blade guides: Deliver high accuracy and straight cuts. Carbide resists wear better than standard steel guides, maintaining alignment longer and producing cleaner cuts even with abrasive materials.
- Reducer unit with hardened and ground gears: Runs in an oil bath for smooth, reliable operation. This transmission system ensures consistent power delivery to the blade and extends component life.
- Mechanical length stop (0-500mm): With graduated scale allows quick setup for repetitive cutting. This enables batch production without measuring each piece individually.
- Coolant system: Integrated into the base 280 M platform, extending blade life and improving cut quality. The system keeps the blade cool and removes swarf from the cutting area.

Frequently Asked Questions
What does DARV mean and how does it differ from the standard 280 M?
The DARV designation indicates three specific upgrades over the base 280 M model: Descent Assist (hydraulic control), dual mitre capability (Angle Right and left), and blade speed Variator. The standard 280 M is manual pull-down with single mitre capability, whereas the DARV adds hydraulic-assisted descent, cutting angles in both directions (60° right and 45° left), and variable blade speed control.
How does the hydraulic descent assist work?
You manually lift the cutting bow, then turn the hydraulic lock dial fully right to engage it, which holds the bow in position. When ready to cut, pull the trigger with your left hand and press the green start button to begin descent. The right-hand dial on the control panel adjusts descent speed to match your material and cutting requirements. Turning the hydraulic lock anticlockwise returns the machine to manual mode.
Can this machine cut stainless steel?
Yes. The two-speed motor provides a 35 metres per minute setting specifically for stainless steel cutting. Stainless requires slower cutting speeds to prevent work hardening. Use the appropriate blade type (typically bimetal with correct tooth pitch for stainless) along with the coolant system for best results.
What's the actual weight of this machine?
The Bianco 280 M-DARV weighs 515kg. This is significantly heavier than the base 280 M model (300kg) due to the additional hydraulic systems, dual mitre mechanism, and blade speed variator components.
What blade size does this machine use?
The machine uses 2450 x 27 x 0.9mm bandsaw blades. In imperial measurements, this is 96.5 inches long by 1 inch wide by 0.035 inches thick. Standard bimetal blades in various tooth configurations are widely available for this size.
What power supply does this require?
Based on standard Bianco 280 series specifications, this machine typically operates on 400V 3-phase power supply, which is standard for industrial equipment in the UK and Europe.
