Bianco 420 Semi Automatic - 420mm Extra Large Capacity
The Bianco 420 SA E is a semi automatic mitre bandsaw designed for professional metal cutting with hydraulic controls and 300mm round cutting capacity. This Italian-manufactured machine features automatic bow return, hydraulic vice operation, and dual speed cutting for efficient production work.
This semi automatic bandsaw handles the cutting cycle for you once you position your material. The hydraulic system controls the vice pressure, cutting speed, and bow movement automatically. After each cut, the bow returns to its starting position without manual intervention, ready for the next piece. The mitring head swivels up to 60° to the right, allowing you to cut angles without repositioning your material.
Bianco has manufactured bandsaws in Italy for over thirty years, building these machines with cast bow construction from specialized alloys. The dual speed motor provides two cutting speeds (35 and 70 metres per minute), letting you match blade speed to material hardness. The integrated flood coolant system reduces heat buildup, extends blade life, and produces cleaner cuts with fewer burrs.
Applications
- Structural steel fabrication: Cutting structural steel sections including beams, channels, and angles for fabrication work
- Tube and pipe work: Tube and pipe cutting to length for building services and fabrication
- Bar stock processing: Processing round bar stock and solid sections for machining operations
- Flat plate cutting: Flat plate and rectangular section cutting for general metalworking
- Mitre cutting: Mitre cutting at 45° and 60° angles for frames and structural assemblies
- General metalworking: General-purpose metal cutting in fabrication shops, engineering workshops, and educational facilities
Key Features & Benefits
- Semi-automatic operation: Completes the cutting cycle automatically once you engage the hydraulic system, reducing operator effort and speeding up production
- Hydraulic vice with variable pressure: Clamps material securely without manual tightening, ensuring consistent grip force across your production run
- 60° right mitring capability: Lets you cut angles from 0° through 45° to 60° by swiveling the cutting head, eliminating material repositioning
- Dual-speed motor (35 and 70 m/min): Provides two blade speeds to match different materials, with slower speeds for harder steels and faster speeds for quicker cycles on softer materials
- Automatic bow return: Resets the cutting head to starting position after completing each cut, eliminating manual repositioning between cuts
- Flood coolant system: Circulates cutting fluid continuously during operation, cooling the blade and workpiece to extend blade life and improve cut quality
- Carbide blade guides: Maintain precise blade tracking and positioning throughout the cut, ensuring accuracy and reducing blade deflection
- Blade tension indicator: Provides visual confirmation that your blade is properly tensioned for optimal cutting performance

Frequently Asked Questions
What materials can the Bianco 420 SA E cut?
This bandsaw is designed for cutting ferrous metals including mild steel and stainless steel. It handles tubes, pipes, solid round bar, flat plates, structural sections like angles and channels, and box sections. The dual-speed motor lets you adjust blade speed based on material hardness.
Does the machine cut angles on both left and right sides?
The 420 SA E is a single right-mitring model. It cuts angles to the right side only (0°, 45°, and 60° right). If you need double mitring with both left and right angle cuts, Bianco manufactures separate models with that capability.
What's the actual footprint of this machine?
The machine measures 1200mm long by 1650mm wide, with a height of 1900mm. The working bed height sits at 830mm from the floor. You'll need adequate clearance around all sides for material handling and maintenance access.
Is the machine ready to use when it arrives?
Yes. The machine arrives fully assembled and tested. It includes a starter set of Goldcut blades and coolant. You'll need to position it on a level surface, connect 415V three-phase power, and fill the coolant system before operation.
How do the two blade speeds work?
The machine has a two-speed motor providing cutting speeds of 35 or 70 metres per minute. You select the appropriate speed based on your material. Use 35 m/min for harder materials like stainless steel or larger cross-sections. Use 70 m/min for faster cutting of softer materials or smaller sections.
What maintenance does this machine require?
Regular maintenance includes checking blade tension using the built-in indicator, cleaning the swarf brush, topping up coolant levels, and replacing worn blades. The hydraulic system and carbide blade guides require minimal maintenance under normal operating conditions.
