A complete guide to choosing your professional shears and nibblers
Which shears should I choose depending on the thickness of the metal I need to cut?
The choice of shears depends directly on the thickness and type of material. For mild steel sheet up to 1.2 mm (18 gauge), a manual Wiss or Irwin aircraft shear is perfectly adequate. Above 1.6 mm (16 gauge), opt for a Dewalt or Makita electric shear delivering 2000-2500 strokes per minute.
For 2-3 mm stainless steel and aluminum, nibblers are the preferred tool for their clean, distortion-free cuts. Knipex lever shears offer a 4:1 leverage ratio, allowing you to cut 2 mm steel with 75% less effort. Quebec professionals favor 18V-20V cordless models for maximum mobility on winter worksites where extension cords make the job difficult.

How do electric nibblers work and what are their advantages for cutting metal?
An electric nibbler cuts metal by rapid punching: a moving punch strikes a fixed die at a high frequency (1000-3000 blows/min), removing tiny chips of 2-4 mm. Unlike shears, which cut, the nibbler perforates, preventing edge deformation even on thin sheet metal as thin as 0.6 mm. The Fein and Metabo HPT models cut to a minimum radius of 30 mm, impossible with straight shears. Typical capacities: mild steel 2.5 mm, stainless steel 2 mm, aluminum 3 mm.
Major advantage: cuts through solid sheet metal without an entry point, ideal for HVAC ventilation cutouts. Pneumatic nibblers require a constant 90 PSI. For Quebec workshops, opt for cordless electric models that eliminate the need for a compressor and bulky hoses. Average power consumption: 500-700W for professional corded models.

Blade and cutting edge technologies: why do aviation shears dominate the professional market?
Aviation shears take their name from their historical use in aeronautics for cutting aircraft aluminum. Their three-blade design (two upper blades, one lower blade) with an optimized cutting angle of 22-25° ensures exceptional sharpness without burrs.
The blades are forged from high-carbon steel (0.7-0.9%) and then hardened to 58-62 HRC (Rockwell hardness). Wiss, a pioneer since 1848, sharpens its blades with a precision of 0.01 mm. Universal color coding: yellow handles (straight cut), red (left), green (right). Lenox shears incorporate bi-metal technology: a flexible body and an ultra-hard cutting edge that lasts 3x longer.
Stanley offers a TiN (titanium nitride) coating that reduces friction by 40%. For galvanized sheet metal commonly used in Quebec (roofing, ventilation), choose stainless steel blades to prevent premature corrosion. Lifespan: 5,000-10,000 cuts depending on maintenance.

What power and autonomy do your cordless shears need for professional construction sites?
Professional cordless electric shears operate on 18V lithium-ion batteries (Dewalt, Makita) or 20V Max (equivalent American system). Optimal cutting capacity requires a minimum 4.0 Ah battery, ideally 5.0-6.0 Ah for a full day's work. A Dewalt DCS494 with a 5.0 Ah battery can cut 120 linear meters of 18-gauge sheet metal before needing a recharge.
Brushless motor power: 400-600W equivalent, torque 8-12 Nm. Variable speed 0-2500 SPM (strokes/minute) allows adaptation according to material: slow for stainless steel (avoids overheating), fast for aluminum.
Actual battery life on a Quebec winter worksite: -15°C reduces battery capacity by 20-30%; spare batteries are recommended. Metabo HPT nibblers consume more power (800-1000W); corded models are recommended for intensive workshop use. Fast charging time: 30-45 minutes to 80% capacity with modern chargers.

Ergonomics and accessories: maximize the comfort and versatility of your cutting tools
The ergonomics of shears directly impact productivity and the prevention of musculoskeletal disorders (MSDs). Craftsman and Knipex non-slip, dual-material handles reduce fatigue during extended use. Optimal weight: manual shears 300-450g, electric shears 1.8-2.5 kg with battery.
360° rotating nibblers (Fein) allow cuts in any position without wrist strain. A progressive trigger improves control, essential for tight curves. Essential accessories: straight cutting guide for perfect lines, cutting compass for repetitive circles, chip collection trays (nibblers generate 2-3 kg of chips per day with intensive use).
Integrated LED lighting (Makita) illuminates the cutting line in confined spaces typical of industrial sites. Compatibility: Check that the batteries are compatible with your existing 18V/20V system to avoid needing multiple chargers. A belt hook and hard case protect your investment during transport.
