Best Reciprocating Saw for Exhaust Work (2026)

Compare the picks

*Power, stroke rate, weight and warranty are the figures each listing states; “Not stated” means the listing gives no figure. 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, with the weights published on the How We Pick page. A stated safety certification earns safety points, and none of these listings states one. Warranty points need a concrete term on the listing.

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

Four saws and one blade set were compared. Three of the saws run on batteries and one runs on a cord. Two listings state a stroke rate, two state a weight, and two state a warranty term. The blade set is the only pick that fully describes its teeth, length and the pipe sizes it handles, which is more cutting detail than most of the saws give about blades. Compatibility is spelled out only on the blade set, which names Bosch, DeWalt, Milwaukee, Makita and other brands its 1/2 in shank fits.

Buying guide: the best reciprocating saw for exhaust work

Exhaust pipe is thin-wall steel that rusts, so the setup matters as much as the saw: enough power, a blade made for metal, and a body that fits where the pipe runs. The sections below follow only what the listings publish.

Corded or cordless

Three picks here run on batteries and one on a cord. The corded Bosch lists 14 amps and 1680 watts, the strongest power figure in the group, but it needs an outlet within reach of the car. The 18V Milwaukee is a bare tool and the 18V RYOBI is tool only, so each needs a battery and charger bought separately unless one is already on the shelf. The Fanttik carries its own 14.8 Wh battery and charges over Type-C. The Bosch is the only pick that lists both its voltage, 120 volts, and its draw, 1680 watts, in the spec table. Under a car, cordless wins on movement; corded wins on sustained power.

Stroke rate and control

Two listings state a stroke rate: the RYOBI at up to 3,000 strokes per minute and the Fanttik at 0 to 2200 SPM with variable speed. A higher stroke rate cuts faster in thin metal, and variable speed helps start the cut without the blade skating across the pipe. One-handed designs like the Milwaukee and the RYOBI trade leverage for control in tight spots. The Milwaukee lists an anti-vibration handle and the Bosch lists a counterbalance vibration control system. Where a listing states no figure, this guide does not guess one.

Blade choice for exhaust pipe

The blade does the cutting. The TOLESA set is the only pick that describes its blades in full: 9-inch, 14 TPI, bi-metal with an 8% cobalt edge and a 0.9 mm thin wall, rated for sheet metal from 0.1 to 0.3 in and solid pipe under 7 in in diameter. Fine teeth like 14 TPI suit thin-wall exhaust tubing, and the set teeth with the thin wall are made to keep heat down. Its 1/2 in shank fits the saws from Bosch, DeWalt, Milwaukee, Makita and the other brands the listing names, which covers every saw here except the Fanttik. The Fanttik clamp takes T-shank jigsaw blades instead of standard reciprocating saw blades, which narrows blade choice for metal work.

Blade changes

Under a car, a blade change should take seconds and no tools. The Milwaukee quick-lock clamp and the RYOBI rapid blade change system are both described as tool-free, and the Fanttik is tool-free as well. The Bosch listing does not describe its blade change, so no claim is made for it. The Fanttik clamp gap is 1.4 mm and takes blades 3 to 4 in long, worth checking before buying blades for it.

Weight and reach

Two listings state a weight: the RYOBI at 3.8 lb and the Bosch at 8.7 lb in its spec table, 8 lb in its bullets. A lighter saw is easier to hold overhead, which is the position exhaust work often demands; a heavier saw leans into the cut, which suits steady work on a removed section. Stated lengths run from 8.92 in on the Fanttik to 18.4 in on the Bosch, so measure the space around the section to cut before choosing.

Garage Fit Check

• Space: the Fanttik measures 8.92 by 2.4 by 1 in and the Milwaukee and RYOBI are one-handed and compact, all suited to tight spots; the Bosch is a full-size saw at 18.4 by 4 by 6.3 in.
• Power: the Milwaukee is a bare tool and the RYOBI is tool only, so plan on an 18V battery and charger for each; the Bosch needs a 120V outlet; the Fanttik charges over Type-C with its built-in 14.8 Wh battery.
• Storage: the Bosch and the Fanttik both include a bag, while the other listings describe no case.
• Before the first cut: match the blade to the clamp, 1/2 in shank blades for the standard clamps and T-shank jigsaw blades 3 to 4 in long for the Fanttik, and choose a metal blade such as the 14 TPI set for exhaust pipe.

Frequently Asked Questions

What blade should I use to cut exhaust pipe?

A bi-metal blade with fine teeth made for metal, like the 14 TPI set here: 9-inch blades with an 8% cobalt edge and a 0.9 mm thin wall, rated for pipe under 7 in in diameter. The 1/2 in shank fits the standard clamps on the saws in this guide except the Fanttik, which takes T-shank jigsaw blades.

Is a cordless reciprocating saw strong enough for exhaust work?

For thin-wall exhaust tubing, yes. The 18V Milwaukee and RYOBI saws are brushless and compact, and the RYOBI lists up to 3,000 strokes per minute. The corded Bosch lists 14 amps and 1680 watts for heavier or badly rusted sections where sustained power helps. No listing states a cutting capacity for exhaust pipe, so match the saw to the thickest section expected.

How heavy are these saws?

The RYOBI lists 3.8 lb and the Bosch lists 8.7 lb in its spec table, 8 lb in its bullets. The Milwaukee and Fanttik listings state no weight figure. Lighter saws are easier to hold overhead; heavier saws sit steadier for straight cuts.

Do these saws come with batteries and blades?

The Milwaukee is a bare tool and the RYOBI is tool only, so both need a battery and charger bought separately. The Fanttik has a built-in 14.8 Wh battery and ships with five 4-inch blades. The Bosch listing includes a bag, and neither the Bosch nor the RYOBI listing describes an included blade.

What warranties do these picks carry?

The Milwaukee listing states a 5-year tool warranty, and the Bosch states a 1-year warranty with a 30-day money-back guarantee. The TOLESA, RYOBI and Fanttik listings state no warranty term.
