What Are Metal Guillotine Shears?
Metal guillotine shears are machines designed to cut sheet metal and other metal materials into precise sizes. They feature a long, hardened metal blade that moves in a vertical motion, applying pressure to the material placed underneath to create a clean cut. These shears are typically used for cutting straight lines on metal sheets, offering uniform results with minimal burrs or distortion.
The main advantages of using guillotine shears include:
– Precision: They deliver straight, clean cuts.
– Versatility: Capable of cutting a wide range of materials, from thin sheets to thick metal plates.
– Efficiency: The motorized versions can handle high-volume cutting, which is ideal for industrial applications.
Types of Guillotine Shears
Manual Guillotine Shears
Manual guillotine shears are operated by hand, using physical force to move the blade. They are more affordable and often used for smaller-scale tasks or workshops. However, they require more effort and time to operate compared to motorized shears.
Examples: KAKA HS-30, Pepetools 4″ Guillotine
Motorized Guillotine Shears
Motorized guillotine shears are driven by electric motors, providing higher cutting power and speed. These shears are ideal for handling larger volumes and thicker materials. They also offer higher precision and control.
Examples: CIDAN EVO DUO, KNUTH Hydraulic Shears
Hydraulic Guillotine Shears
Hydraulic guillotine shears use hydraulic power to apply force on the material. These are typically more robust and capable of cutting thicker materials with greater ease. They often come with advanced features like adjustable cutting angles and can be controlled via NC (Numerical Control) or CNC (Computer Numerical Control) systems.

Key Features of Metal Guillotine Shears
Cutting Capacity
Cutting capacity refers to the thickness and size of metal the shear can handle. Some shears can only cut thin gauges (up to 16-gauge), while others can handle thicker materials, such as 6 mm or more of mild steel. Choosing a shear with the right cutting capacity is crucial for ensuring efficiency in your operations.
Control System
- Manual Control: Manual shears are typically operated by a foot pedal or lever. These are less expensive but require more manual effort.
- NC/CNC Control: Advanced shears feature NC or CNC controls, which offer precision cutting through automated systems. These are suitable for high-volume production and more complex tasks.
Material Support
Material support is essential for ensuring stability during the cutting process. Many shears feature adjustable backgauges and sheet supports that help position and stabilize the metal as it’s cut.
Size and Weight
Guillotine shears come in a range of sizes, from small bench-top models for hobbyists and smaller businesses to large, floor-standing machines for industrial applications. The size will dictate the material it can handle and its suitability for various environments.
Comparison of Technical Features
| Model | Cutting Capacity | Control Type | Max Sheet Size | Motor Power | Price Range |
|---|---|---|---|---|---|
| CIDAN EVO DUO | 10 mm (mild steel) | NC/CNC | Large | High | High |
| CIDAN RAPIDO | 6 mm (mild steel) | Manual/CNC | Medium | Medium | Medium |
| Pepetools 4″ Guillotine | 0.06″ (16-gauge) | Manual | Small | Low | Low |
| KNUTH Hydraulic Shears | 10 mm (steel) | CNC/Manual | Large | High | High |
| KAKA HS-30 | 16-gauge | Manual | Medium | Low | Low |
| KAKA HS-52 | 16-gauge | Manual | Large | Low | Medium |
| Tommy Industrial Hydraulic | Heavy-duty | CNC/Manual | Large | Very High | High |
| Durston Tools Guillotine | Varies by model | Manual | Small to Medium | Low | Low |
