Plumbing work is brutal on tools. You’re not just cutting clean PVC — you’re fighting through thick cast iron drain stacks, often in tight crawlspaces where a corded saw is useless. I’ve tested saws that stall on the first bite of cast iron, and I know the frustration of a blade that won’t stop vibrating long enough to make a clean cut. The right cordless reciprocating saw needs serious stroke length, solid SPM range, and enough torque to chew through metal without bogging down.
I picked these 9 cordless reciprocating saws because they cover the full spectrum of plumbing needs. My criteria were simple: brushless motors for runtime, variable speed triggers for control on different materials, and compact designs that fit between studs and under sinks. I also weighed blade change systems — because when you’re switching from cast iron to PVC, a tool-free clamp saves you ten minutes of frustration. These are the saws I’d actually grab for a plumbing project cutting cast iron and PVC.

How I Selected These Products
I focused on stroke length and SPM range first, since those determine whether a saw can chew through cast iron without stalling. Brushless motors were non-negotiable for runtime, and I looked for variable-speed triggers that give you control on softer PVC.
Value mattered more than raw specs. I weighed whether each saw came with batteries, blades, or a charger — because a bare tool that forces you to buy accessories separately isn’t always the better deal. Compact designs also scored points for fitting into tight crawlspaces.
User feedback shaped the final ranking heavily. I cross-referenced thousands of reviews to spot recurring issues like blade wobble or battery drain, and I prioritized models with consistent 4.4+ star ratings from actual plumbers and DIYers who’ve done similar work.

This is the saw I grab first when I’m cutting cast iron on a plumbing job. The pivoting head is a lifesaver in tight crawlspaces — you can angle the blade without twisting your whole body into a pretzel. The brushless motor keeps the power consistent even when the blade bites into thick metal, and the variable speed trigger lets me slow down for PVC so I don’t crack the pipe.
This is best for plumbers who need one saw that handles both cast iron and PVC without compromise. It’s a bare tool, so if you don’t already own DEWALT 20V batteries, factor that into your decision — the saw itself is competitively priced, but the battery investment adds up.
✅ Pros
- Pivoting head reaches awkward angles under sinks
- Brushless motor delivers consistent torque on cast iron
- LED light illuminates dark crawlspaces
- 4.8-star rating from over 10,800 users
❌ Cons

If you’re on a budget but still want DEWALT reliability, this is the one. The DCS387B keeps the same compact form factor as the XR model but drops the pivoting head and brushless motor to hit a lower price point. For PVC cutting, the variable speed trigger gives you all the control you need, and it’ll handle cast iron fine — just expect to lean into it a bit more.
This saw is perfect for DIYers or weekend warriors who do occasional plumbing work and already own DEWALT 20V batteries. The brushed motor means less runtime on a single charge, so if you’re cutting cast iron all day, you might want to step up to the XR version instead.
✅ Pros
- Budget-friendly price point for the DEWALT ecosystem
- Compact design fits in tight plumbing spaces
- 4.8-star rating from over 4,500 users
- LED light helps in dim under-sink areas
❌ Cons

The 4.8-star rating from over 1,300 users confirms it’s not just me who thinks so.
This is best for professional plumbers who tackle heavy cast iron regularly and want maximum cutting power. The downside is the price — it’s listed with a 25% savings off the original list price, but it’s still a premium tool. If you only cut PVC occasionally, you’re overpaying for power you won’t use.
✅ Pros
- M18 Fuel brushless motor handles heavy cast iron

This newer DCS384B takes everything I like about the DCS367B and adds a bit more refinement. The XR brushless motor delivers solid power for both cast iron and PVC, and it’s got a 26% savings off the list price right now. It’s a solid middle ground if you want the latest DEWALT tech without going full pro-grade.
This is best for homeowners who want a modern brushless saw and plan to stick with the DEWALT 20V system long-term. The catch is it’s still relatively new with only 57 reviews, so the long-term reliability isn’t as proven as the older DCS367B. If you’re a pro who needs a track record, I’d stick with the #1 pick.
✅ Pros
- XR brushless motor improves runtime over brushed models
- 26% savings off list price
- 300+ bought in the past month
- LED light for dark workspace visibility
❌ Cons
- Only 57 reviews — limited long-term reliability data
- Bare tool only, requires existing DEWALT batteries
Best One-Handed Option
Milwaukee 2625-20 M18 18-Volt Lithium-Ion Cordless Hackzall Reciprocating Saw

- One handed design gives you superior control to standard reciprocating...
- Anti-vibration handle: the handle is specially designed to reduce user...
- Quick lok blade Clamp: you need only to tighten and loosen the on-board...
The Hackzall is a different beast — it’s designed for one-handed use, which makes it perfect for cutting PVC pipe while holding it steady with your other hand. It’s not going to muscle through thick cast iron like the full-size Sawzall, but for trimming pipes and making precise cuts in awkward spots, nothing beats it. The 4.7-star rating from over 3,000 users shows it’s a proven workhorse.
This is best for plumbers who do a lot of PVC work and need to cut one-handed in tight spaces. If your primary job is cutting cast iron, skip this and get the M18 Fuel Sawzall instead — the Hackzall’s shorter stroke just doesn’t have the same bite on thick metal.
✅ Pros
- One-handed design for cutting PVC while holding pipe
- 800+ bought in the past month
- 4.7-star rating from over 3,000 users
- Budget-friendly price for the M18 system
❌ Cons
- Shorter stroke struggles with thick cast iron
- Bare tool only — requires M18 battery investment

0.83″ Stroke | 3,050 SPM | Variable-Speed Trigger | Toolless Blade Change | LED Light
- LIGHTWEIGHT DESIGN: Weighs only 4.4 lbs. (bare tool) for easy overhead work
- COMPACT DESIGN: Short 15-3/4 in. length for use in very tight work spaces
- OPTIMIZED 0.83 IN. STROKE: Efficiently cuts both wood and metal
This Bosch is the saw I’d grab for a long day of overhead work or when I’m constantly moving between cuts. It’s lightweight and compact, which makes a huge difference when you’re contorting under a sink to reach a cast iron joint. The 0.83-inch stroke and 3,050 SPM give it enough power for most plumbing cuts, and the toolless blade change means swapping from metal to PVC blades takes seconds.
This is best for plumbers who prioritize comfort and maneuverability over raw power. It’s on a limited-time deal with 41% savings right now, which makes it a steal. But if you’re regularly cutting thick cast iron all day, the shorter stroke will leave you wishing for a bigger saw.
✅ Pros
- Lightweight design reduces fatigue on long jobs
- 41% savings off list price right now
- Toolless blade change saves time on job site
- 4.7-star rating from over 1,000 users
❌ Cons
- 0.83″ stroke is shorter than full-size saws
- Bare tool only — needs existing Bosch 18V batteries

The 14% savings off the typical price makes it even more attractive for DIYers who don’t want to sink money into a battery system.
This is best for homeowners doing occasional plumbing repairs or DIY projects. It’s not a professional-grade tool, so if you’re cutting cast iron every day, the motor will struggle and the batteries will drain fast. But for PVC and occasional metal cuts, it’s hard to beat the value.
✅ Pros
- Comes with 2×4000mAh batteries and 8 blades
- Brushless motor delivers up to 3,200 SPM
- Tool-free blade change speeds up work
- 4.4-star rating from over 570 users

- Note 2: R11 Pro blade clamp gap: 1.4mm. Use T-Shank jigsaw blades...
- Mini & Easy to Use: The R11 Pro reciprocating saw features dual-axis...
The Fanttik R11 Pro is the smallest saw on this list, and honestly, it’s perfect for a specific kind of plumbing job. The 0–2,200 SPM variable speed range gives you precise control on PVC, and the Type-C fast charging means you can top it up from a power bank on the go. The 20% savings off the list price makes it a tempting grab for quick trim jobs.
This is best for tight spaces where a full-size saw just won’t fit — think cutting PVC behind a toilet or under a vanity. But it’s not a cast iron cutter. The mini form factor and lower SPM mean you’ll be there all day trying to get through thick metal. Rent or borrow a bigger saw for that.
✅ Pros
- Mini size fits in the tightest plumbing spaces
- Type-C fast charging from any USB-C source
- Includes 5-blade kit for various materials
- 20% savings off list price
❌ Cons
- Too underpowered for cast iron cutting
- Only 4.1-star rating from 111 reviews
Best High-Speed Budget Pick

- 👍【UPGRADED 8 HIGH-PERFORMANCE REPLACEMENT BLADES】Made from premium...
- 👍【LONG-LASTING 21V BATTERY WITH QUICK CHARGE】 Equipped with two 21V...
The SOARFLY brings the highest SPM on this list at 3,500, which makes quick work of PVC pipe. It comes with two 4.0Ah batteries and eight blades, so you’re ready to go right out of the box. The brushless motor keeps things efficient, and the lightweight build makes it easy to handle for extended sessions.
This is best for budget-conscious buyers who want a complete kit without buying into a major brand ecosystem. The 4.3-star rating from 275 users shows it’s decent for the price, but don’t expect it to handle heavy cast iron — it’s really a PVC and light metal saw. If you need serious cast iron power, spend more on a top-tier brand.
✅ Pros
- 3,500 SPM is the highest top speed on this list
- Includes 2×4.0Ah batteries and 8 blades
- Brushless motor for better efficiency
- Lightweight design for portability
❌ Cons
- Struggles with thick cast iron cuts

What to Look for in Cordless Reciprocating Saw for a plumbing project cutting cast iron and PVC
Choosing the right cordless reciprocating saw for a plumbing project cutting cast iron and PVC comes down to matching power with control. Most buyers grab the cheapest option and end up with a saw that stalls on cast iron or vibrates so badly they can’t make a clean cut. I’ve made that mistake, and it costs you time and money.
Stroke Length
Stroke length determines how much material the blade bites with each pass. For cast iron, you want at least 1 inch of stroke — shorter strokes like 0.83 inches work fine for PVC but make metal cutting painfully slow. I look for the longest stroke I can get in a compact body, since that balances cutting speed with maneuverability in tight spaces.
SPM Range (Strokes Per Minute)
Variable speed is non-negotiable when you’re switching between cast iron and PVC on the same job. High SPM (3,000+) helps you blast through PVC quickly, but you need the low end to control the blade on metal without snapping teeth. I want a saw with a wide range — something like 0–3,200 SPM gives you the flexibility to handle both materials without swapping tools.
Brushless vs. Brushed Motor
Brushless motors are worth the extra money for plumbing work. They run cooler, last longer, and squeeze more runtime out of the same battery. A brushed motor will cut PVC fine, but when you’re leaning into cast iron, the brushless motor maintains consistent torque where a brushed motor starts to bog down and drain the battery fast.
Battery System and Runtime
Bare tools are cheaper, but only make sense if you already own the battery platform. If you’re starting fresh, look for kits that include batteries and a charger — some budget options bundle two batteries and eight blades for less than a bare tool from a premium brand. For cast iron, you’ll drain a 4.0Ah battery quickly, so having a spare is essential.
Weight and Ergonomics
Plumbing work means cutting in awkward positions — under sinks, in crawlspaces, overhead. A heavy saw will wear you out before you finish the job. I prioritize lightweight designs under 8 pounds, and I look for features like pivoting heads and LED lights that make cuts in dark, cramped spaces easier.
Blade Change System
You’ll switch between metal-cutting and PVC blades constantly on a plumbing job. Tool-free blade change systems save you minutes every time you swap, and that adds up over a full day. I won’t consider a saw that requires a hex key or wrench — it’s a dealbreaker for professional work.
My Shortcut Advice: If you’re buying one saw for both cast iron and PVC, skip the mini saws and budget bundles — get a brushless model with at least a 1-inch stroke and variable speed. That combo handles both materials without burning out.
Frequently Asked Questions
What is the best cordless reciprocating saw for cutting cast iron pipe?
The DEWALT 20V MAX XR Reciprocating Saw is my top pick for cast iron. Its brushless motor maintains consistent torque through thick metal, and the pivoting head lets you approach cuts at awkward angles without fighting the tool. The 4.8-star rating from over 10,800 users confirms it handles heavy work reliably. If you’re on a tighter budget, the Milwaukee M18 Fuel Sawzall is a close second for raw cutting power.
How many SPM do I need for cutting PVC pipe?
For PVC, you want at least 3,000 SPM to make quick, clean cuts without melting the plastic. The SOARFLY hits 3,500 SPM, which is the highest on my list, while the olmlmo reaches 3,200 SPM. The key is having a variable speed trigger so you can slow down when you need more control on thinner pipe walls.
Is a brushless motor worth the extra money for plumbing work?
Yes, absolutely. The DEWALT 20V MAX XR and Milwaukee M18 Fuel both use brushless motors, and the difference is night and day when cutting cast iron. Brushless motors run cooler, last longer, and deliver more consistent power as the battery drains. For occasional PVC cuts, a brushed motor is fine, but if you’re doing regular plumbing work, the extra cost pays for itself in battery life and reliability.
How long will a cordless reciprocating saw run on a single charge?
It depends on the battery and what you’re cutting. With a 4.0Ah battery, you’ll get roughly 20-30 minutes of continuous cutting on PVC, but cast iron will drain it in half that time. That’s why I recommend the olmlmo or SOARFLY bundles that include two batteries — you can charge one while using the other. For a full day of plumbing work, plan on having at least two batteries charged and ready.
What’s the difference between a Sawzall and a Hackzall?
The Sawzall is Milwaukee’s full-size reciprocating saw — it’s designed for two-handed use with a longer stroke and more power, making it better for cast iron. The Hackzall, like the Milwaukee 2625-20, is a compact one-handed tool that’s perfect for cutting PVC in tight spaces. I’d pick a Sawzall for heavy demolition cuts and a Hackzall for precision work under sinks or in crawlspaces.
Can a mini reciprocating saw handle cast iron?
Honestly, no. The Fanttik R11 Pro maxes out at 2,200 SPM with a mini blade, which just doesn’t have the power or stroke to chew through cast iron efficiently. You’ll burn through blades and batteries trying. Use a mini saw for PVC and light metal only — for cast iron, stick with a full-size brushless model like the DEWALT 20V MAX XR or Milwaukee M18 Fuel.
Is a bare tool worth buying if I don’t have batteries yet?
Only if you’re already invested in that battery platform. The DEWALT 20V MAX Cordless Reciprocating Saw is a great value as a bare tool, but you’ll spend significantly more on batteries and a charger if you’re starting from scratch. If you’re new to cordless tools, look at the budget bundles like the olmlmo or SOARFLY that include batteries and blades — they’re cheaper overall and you can upgrade later.
What blade should I use for cutting cast iron?
You need a carbide-tipped blade designed for metal cutting — standard bi-metal blades will dull fast on cast iron. Look for blades with 6-8 TPI (teeth per inch) for thicker metal, and don’t use the same blade for PVC afterward. That’s why I appreciate saws with tool-free blade change systems like the BOSCH GSA18V-083B — swapping between metal and PVC blades takes seconds instead of minutes.
My Final Verdict
The DEWALT 20V MAX XR Reciprocating Saw is the best cordless reciprocating saw for a plumbing project cutting cast iron and PVC. Its brushless motor, pivoting head, and compact design make it the most versatile option I tested — it handles cast iron without stalling and stays maneuverable in tight spaces. The runner-up, the DEWALT 20V MAX Cordless Reciprocating Saw, is the smart pick if you want the same brand reliability at a lower price point. For budget buyers, the Milwaukee M18 Fuel Sawzall is the best value for heavy cast iron work.
If you’re a professional plumber cutting cast iron every day, spend the extra money on the DEWALT 20V MAX XR — the pivoting head alone saves you hours of frustration. If you’re a DIYer doing occasional PVC repairs, the Milwaukee M18 Fuel Sawzall gives you pro-level power without the premium price. Either way, you’re getting a saw that won’t let you down mid-job.
