1. Power Source: Cordless Lithium-Ion vs. 120V AC Corded
Your first major decision is choosing how your jigsaw receives power:
- Cordless 18V / 20V MAX: The standard on modern American job sites. High-efficiency brushless motors on tools like the DEWALT DCS334B and Milwaukee 2737-20 match corded torque while eliminating annoying cord snagging across 4x8 plywood sheets.
- 120V Corded (6.5A – 7.2A): Benchmark tools like the Bosch JS470E and DEWALT DW331K deliver continuous power for thick hardwood beams without battery swapping pauses.
2. Grip Configuration: Top-Handle (D-Handle) vs. Barrel-Grip
- Top-Handle (D-Handle): The most familiar American style. Features a top handle with a variable-speed trigger. Perfect for downward feed force on 2x4 framing and single-handed long rips.
- Barrel-Grip: Preferred by custom cabinetmakers and European-trained woodworkers. Your hand grips the body directly behind the blade, giving remarkable control for delicate curved scrollwork and cutting from underneath to avoid top-face tear-out.
3. Motor Architecture: Brushless vs. Brushed
Always prioritize a brushless motor for cordless platforms:
- Delivers 30% to 50% more cuts per battery charge.
- Onboard electronic governors prevent the motor from bogging down when encountering dense knots.
- Zero carbon brush wear for a significantly longer tool life.
4. Base Plate Rigidity and Bevel Detents
Avoid cheap stamped sheet-metal base plates; they bend when dropped, ruining 90-degree square cuts forever. Look for:
- Heavy die-cast aluminum or magnesium shoe plates.
- Tool-free bevel levers with positive tactile stops at 0°, 15°, 30°, and 45°.
- Non-marring plastic shoe covers to protect expensive pre-finished cabinetry and laminates.
