Best Cordless Reciprocating Saw for Home Mechanics (2026): 5 Kits Compared

Compare the picks

Specifications are manufacturer rated, as published on each listing and collected 21 October 2026.

How we scored them

Each saw is scored on performance, build, value, safety and warranty, using only what the listing publishes. Stated speed, stroke, battery capacity and included kit earn the most; nothing stated on safety or warranty means no points there.

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.

What the listings tell you

Five cordless saws, all with tool-free blade changes and rectangular blades. Speeds run from 3,000 spm to 3,500 SPM. Strokes run from 7/8 in to 15 cm across the listings. Four come with batteries: the TaskStar with 2 4.0Ah, the two FULLYEAs with 2 2.0Ah each, and the DEWALT with a 5.0Ah pack; the BLACK+DECKER is the tool only. Blade counts run from 1 to 8. Two listings state a warranty: 3 years on the DEWALT and 2 years on the BLACK+DECKER. Three listings name a safety feature: a safety lock on the TaskStar, an electric brake on the BLACK+DECKER and a safety protection switch on the blue FULLYEA. Blade counts and kit extras are where the listings diverge most: from a single blade and no battery to 8 blades with gloves, glasses and a bag.

Buying guide: best cordless reciprocating saw for home mechanics

Battery platform and what is included

Four of the five are kits. The TaskStar brings 2 4.0Ah batteries, the biggest capacity here; the two FULLYEAs bring 2 2.0Ah each; the DEWALT brings one 5.0Ah pack with a charger and a kit box. The BLACK+DECKER is the bare tool: battery not included, so it only makes sense if you already own the 20V POWERCONNECT system. The yellow FULLYEA also states compatibility with Makita batteries, which is a real plus for an existing Makita owner. And the BLACK+DECKER only makes sense on the POWERCONNECT platform, since buying into a new battery system for one bare tool is false economy.

Stroke length and speed

Stroke length decides how much material each pass removes. The TaskStar lists a 15 cm stroke, the longest here; the DEWALT lists 1-1/8 in; the BLACK+DECKER lists 7/8 in; both FULLYEAs list 28 mm. Speeds are 3,500 SPM on the TaskStar and both FULLYEAs, and 3,000 spm on the DEWALT and BLACK+DECKER. For cutting capacity, the TaskStar lists wood 50 mm, plastic 130 mm and metal 20 mm; the yellow FULLYEA lists 80 mm plastic, 50 mm wood and 20 mm metal. Those two are the only listings that state cutting depths, so the other three are scored on speed and stroke alone.

Blade changing and extras

Every saw here has tool-free blade change, so the difference is what comes in the box. The TaskStar includes 8 blades, a storage bag, gloves and safety glasses; the yellow FULLYEA includes 4 blades (3 wood, 1 metal) and a portable tool box; the blue FULLYEA includes 4 blades; the DEWALT includes a kit box; the BLACK+DECKER includes 1 blade. Both FULLYEAs and the TaskStar add an LED work light, which matters under a car or in a dim garage. The TaskStar goes further with gloves and safety glasses in the box, the only listing here that bundles PPE with the saw.

Safety features and warranty

Three listings name safety features: the TaskStar has a safety lock to prevent accidental starts, the BLACK+DECKER has an electric brake for enhanced safety, and the blue FULLYEA has a safety protection switch. On warranty, the DEWALT states 3 years limited and the BLACK+DECKER states 2 years limited; the other three state no concrete term. A stated warranty is the only promise that survives the purchase, so it counts. Note the gap: the two FULLYEAs and the TaskStar, the three highest-spec saws on paper, are also the three with no stated warranty term.

Frequently Asked Questions

Do any of these saws come with batteries?

Four do. The TaskStar includes 2 4.0Ah batteries, the DEWALT includes a 5.0Ah battery and charger, and both FULLYEAs include 2 2.0Ah batteries. The BLACK+DECKER is the tool only: battery not included. It runs on the 20V POWERCONNECT system, so it is a buy only for owners of that platform.

What are the stroke lengths?

The TaskStar lists a 15 cm stroke, the DEWALT lists 1-1/8 in, the BLACK+DECKER lists 7/8 in, and both FULLYEAs list 28 mm. Longer strokes remove more material per pass, which is why stroke length sits beside speed in the scoring.

Which saw has the longest warranty?

The DEWALT states a 3 year limited warranty, the longest here. The BLACK+DECKER states a 2 year limited warranty. The TaskStar and both FULLYEAs state no concrete warranty term.

Can these saws cut metal?

All five list metal among their uses. The TaskStar lists a 20 mm metal cutting capacity and the yellow FULLYEA lists 20 mm in metal as well. For exhaust work and rusted fasteners, pair the saw with a metal blade; the yellow FULLYEA includes one.

What is the difference between the two FULLYEA saws?

The yellow one (FSS103-004A) states 21V, includes a portable tool box and states Makita battery compatibility. The blue one (FRS101-006A) states a pure copper motor and a safety protection switch but lists no voltage. Both run 0-3,500 SPM with a 28 mm stroke and 2 2.0Ah batteries. The yellow adds the tool box and Makita compatibility; the blue adds the safety protection switch and the copper motor claim.
