BLACK+DECKER 5A vs 4.5A Jig Saw: Which Cuts Best for 2026?

Price — Black+Decker 4.5A wins

The 4.5A model costs $41.14, $8.85 less than the 5A at $49.99. That's a 17% savings for a slightly lower amp motor.

For occasional users, the savings is meaningful. If you cut plywood a few times a year, that $9 stays in your wallet.

Frequent users should still consider the 5A. The added cutting power prevents stalling on thicker stock, making the investment worth it.

Amperage — Black+Decker 5A wins

The 5A motor delivers 5 amps vs 4.5 amps in the runner-up. That extra 0.5 amp provides noticeably more torque for hardwood and metal.

In daily use, you'll feel the difference on thick 2x4s and pressure-treated lumber. The 5A powers through without bogging down.

Buyers who cut thick material regularly should prioritize amperage. The 4.5A works fine for plywood and thin stock.

Max SPM — Tie

Both saws top out at 3,000 strokes per minute. Neither has a speed advantage for straight cuts.

In practice, both handle similar material speeds with variable-speed triggers. You can dial in the pace for the material.

This dimension doesn't separate the two. Focus on motor power and features instead.

Blade Change — Black+Decker 4.5A wins

The 4.5A uses a quick-clamp system for tool-free swaps. Pop out the old blade and click in a new one — no screwdriver needed.

On the 5A, you'll need a hex key to loosen and tighten screws. That adds a minute per change and risks dropping small hardware.

Frequent blade changers will appreciate the 4.5A's convenience. It's especially helpful when switching between wood and metal blades.

Bevel Capacity — Tie

Both models tilt the base plate to 45° for angled cuts. No advantage either way.

Adjustments are tool-free on both saws. Simply loosen the lever, set the angle, and retighten.

This is a standard feature on corded jigsaws at this price. Neither surprises here.

Orbital Action — Black+Decker 5A wins

The 5A includes 3/4" orbital action for more aggressive cutting. The blade moves in an elliptical path, clearing sawdust faster.

The 4.5A has no orbital setting. Cuts are straight up-and-down, which is gentler on materials but slower.

Orbital action is a must for thick wood and metal. It reduces cutting time and prevents blade overheating.

Weight — Black+Decker 4.5A wins

The 4.5A weighs 4.44 lbs, 0.16 lbs less than the 5A. The difference is small but noticeable in extended use.

Lighter weight reduces fatigue when making multiple cuts overhead or on a ladder. Every ounce counts during a long workshop session.

If you cut all day, the 4.5A is easier on your arms. For occasional use, the weight gap is negligible.

Rating — Black+Decker 5A wins

The 5A holds a 4.7-star average across 11,113 reviews vs 4.6 stars for the 4.5A (9,111 reviews). A small but consistent edge.

Buyers praise the 5A's power and durability. Complaints are rare, mostly about the screw-based blade change.

The 4.5A scores highly for value and ease of use. The slightly lower rating reflects the less powerful motor.

Dust Blower — Black+Decker 4.5A wins

The 4.5A comes with a built-in dust blower to keep the cut line visible. No more stopping to blow away debris.

The 5A lacks this feature. You'll need to clear sawdust manually or use an external blower.

For precision cuts, the dust blower is a real convenience. It helps you follow the line accurately without interruptions.
