How to Choose Cordless Sheet Metal Shears

Cordless sheet metal shears are essential tools for those who work in the light carpentry, roofing, air ducts or metal finishing sectors. They offer freedom of movement, clean cuts and great versatility on construction sites where electricity is often lacking. But how do you choose the right one? Let's find out together.

1. Types of Battery-Powered Shears

First of all, it is important to know the main typologies of sheet metal shears:

  • Straight blade shears: ideal for long and precise straight cuts

  • Curved shears (duck bill or throat): suitable for curved or shaped cuts

  • Punch or nibble shears: perfect for working on corrugated or thick sheets, they allow tight curves without deforming the material

2. Cutting Thickness and Materials

Each shear has thickness limits for specific materials. Before purchasing, check:

  • Maximum thickness in mild steel and stainless steel (e.g. 1.6 mm steel – 1.2 mm stainless steel)

  • Capacity on aluminum or copper

  • Compatibility with corrugated, corrugated or flat sheet metal

Choose a model that guarantees Consistent performance without fatigue even on hard materials.

3. Battery Power and Voltage

Lithium batteries have revolutionized the efficiency of cordless tools. Rate:

  • Voltage: 12V for light use, 18V for professional applications

  • Ampere hour (Ah): the higher the value, the greater the autonomy

  • Compatible battery system: if you work with other tools of the same brand, it is advisable to use interchangeable batteries

4. Weight and Ergonomics

A cordless tool must be light but balanced. Key points to consider:

  • Total weight with battery mounted

  • Non-slip and ergonomic grip

  • Machine body shape suitable for working in narrow spaces or overhead

Ergonomics reduces fatigue and increases precision in long cuts.

5. Cutting Speed and Adjustments

The best cordless shears offer:

  • Adjustable speed (in meters per minute) to adapt to different thicknesses

  • Anti-jam system to ensure continuity of work

  • Electronic overload protection

6. Brands and Reliability

Trust well-known brands in the sector such as:

  • Makita
