A reciprocating saw — often called by the trademarked name "Sawzall" — is the demolition tool of choice for homeowners and contractors alike. Tearing out old drywall, cutting through nail-embedded framing, pruning tree branches, cutting metal pipe, removing rotted deck boards, breaking down pallets, cutting into walls to access plumbing — the reciprocating saw does everything no other saw can do well.
Where a circular saw makes precise straight cuts and a jigsaw handles curves, a reciprocating saw is built for aggressive cutting through mixed materials — often in awkward positions, tight spaces, or through fasteners that would destroy other saw blades.
This guide covers what makes a good reciprocating saw, what specs matter, and the Greenworks 24V POWERALL reciprocating saw built for real project work.
What a Reciprocating Saw Actually Does
A reciprocating saw uses a straight blade that moves rapidly back and forth (reciprocates). Unlike other saws with fixed blade angles or cutting patterns, the reciprocating saw cuts wherever you point it — with the right blade, it cuts almost anything:
- Demolition: Framing, drywall, plaster, subfloor, existing structures.
- Nail-embedded wood: Bi-metal blades cut through nails without damage.
- Metal cutting: Pipe, conduit, rebar, sheet metal (with appropriate blades).
- Tree pruning: Cutting live branches too thick for a hand saw but too small for a chainsaw.
- Awkward-position cutting: Overhead work, behind walls, in tight corners where no other saw fits.
- Plumbing / HVAC: Cutting into walls to access pipes; cutting old pipes for replacement.
You don't buy a reciprocating saw for precision — that's a jigsaw or circular saw. You buy one for the ability to cut aggressively through whatever's in front of you, often in situations where accessibility matters more than clean edges.
SPM (Strokes Per Minute) — The Cutting Speed Spec
Similar to jigsaws, reciprocating saws are measured in strokes per minute — how many times the blade cycles per 60 seconds. Higher SPM = faster cutting.
| SPM Range | Best Fit |
|---|---|
| Under 2,500 SPM | Light demolition. Slow on metal or thick stock. |
| 2,500–3,000 SPM | Residential standard. Handles most demolition and cutting. |
| 3,000+ SPM | Premium residential / prosumer. Fast cutting through mixed materials. |
Variable speed control matters as much as top-end SPM. A variable-speed trigger lets you dial down for precise cuts on metal (where too much speed generates heat and dulls blades), or dial up for fast demolition on wood.
Stroke Length: The Sleeper Spec
Stroke length is how far the blade travels per cycle. This matters more than most buyers realize:
- Under 3/4": Compact and lightweight but slow through thick material.
- 7/8"–1": Residential premium. Each stroke removes more material = faster cutting.
- 1-1/8"+: Contractor territory. Fastest cutting; bulkier tools.
A 1" stroke is the residential sweet spot. Enough to cut fast through 2× lumber, thick metal pipe, and demolition work — without the extra weight and size of contractor-grade saws.
Variable Speed and Trigger Control
All quality reciprocating saws have variable speed triggers, but the range and control differ:
- Wide range (0–3,000 SPM): Best. Delicate cuts at low speed, demolition at top speed.
- Narrow range (1,500–3,000): Compromise. Fine for demolition but harder to control on metal.
Look for variable speed from zero — this lets you start slow on a cut for accuracy, then accelerate once the blade is engaged.
Tool-Free Blade Change
You'll swap blades constantly — wood blade for framing, metal blade for pipe, coarse blade for rough demo. Tool-free blade change is non-negotiable on any serious reciprocating saw:
- Twist-lock or quick-release collar that grips the blade shank
- Change blade in under 5 seconds with no wrench or key
- Accepts universal 1/2" universal shank blades — available from every manufacturer
The Greenworks 24V reciprocating saw includes tool-free blade release and accepts universal blades — Milwaukee, DeWalt, Diablo, and every hardware store brand all work.
Brushless Motors: Standard for Serious Reciprocating Saws
Same rule as every cordless power tool:
- 30% more torque — noticeable when cutting metal or hardwood.
- 50% more runtime per charge (Greenworks' claim on this specific tool).
- 3–5x longer motor life.
- Cooler operation during continuous demolition work.

Lightweight compact design. Genuinely important for reciprocating saw work — you're often cutting overhead, in tight spaces, or in awkward positions. Compact tools reduce fatigue and improve accuracy.
50% more runtime vs previous generation. Manufacturer's claim, but the brushless motor efficiency is real. Meaningful for demolition sessions where blade time matters.
Tool-only pricing at $179. Best buy if you already own 24V POWERALL batteries. Full compatibility with all 200+ tools on the platform.
Reciprocating Saw vs Jigsaw vs Circular Saw
Quick clarification on when to use which:
| Job | Right Saw |
|---|---|
| Long straight cuts in lumber or plywood | Circular saw |
| Curved cuts or decorative shapes | Jigsaw |
| Precision cutouts (sink, outlet, etc.) | Jigsaw |
| Demolition and rough cutting | Reciprocating saw |
| Cutting nail-embedded wood | Reciprocating saw with bi-metal blade |
| Cutting metal pipe, conduit, rebar | Reciprocating saw with metal blade |
| Overhead or awkward-position cuts | Reciprocating saw |
| Tree branch pruning (3"–6") | Reciprocating saw with pruning blade |
Ideally, a serious homeowner shop has all three. The reciprocating saw fills the demolition and mixed-material gap that neither of the other saws handles well.
Reciprocating Saw Blade Basics
The right blade makes all the difference:
- Wood cutting (6 TPI): Fast rough cuts in framing lumber. Aggressive teeth.
- Wood + nails (10 TPI bi-metal): The demo blade. Cuts through nail-embedded wood without breaking.
- Metal (18–24 TPI): Cuts pipe, conduit, sheet metal. Fine teeth reduce heat buildup.
- Pruning (5 TPI): Aggressive tooth pattern designed for green wood.
- Carbide grit (no teeth): For masonry, tile, cast iron. Slow but effective.
Start with a variety pack (wood + bi-metal + metal) under $25. Add specialty blades as projects require. Blades are consumable — dull blades cost more time and money than replacement blades ever will.
Safety
Reciprocating saws are aggressive tools. Key rules:
- Wear safety glasses and gloves. Cutting demolition material sends chips, splinters, and metal fragments flying.
- Watch what's on the other side of your cut. Wires, plumbing, and structural elements often hide in walls. Kill the power to a room before cutting into walls.
- Keep both hands on the tool. One on the trigger, one on the front handle. Reciprocating saws produce significant vibration and torque reaction.
- Let the blade come to a stop before repositioning. Moving a running blade is how injuries happen.
- Change blades often. Dull blades force you to push harder — that's when the tool jerks unexpectedly.
FAQ
How does a reciprocating saw differ from a "Sawzall"?
"Sawzall" is Milwaukee's trademarked brand name for their reciprocating saws — like calling all tissues Kleenex. All Sawzalls are reciprocating saws; not all reciprocating saws are Sawzalls. The tool category is the same.
Can I use this saw to prune tree branches?
Yes, with a pruning blade. Reciprocating saws with pruning blades handle branches up to about 4–6" diameter effectively. Beyond that, use a chainsaw.
How long does a battery last per charge?
On a 2.0Ah battery, expect 30–45 minutes of continuous cutting or 60–90 minutes of intermittent demolition use.
Can I cut concrete or brick?
Only with carbide-grit blades, and only slowly. For serious masonry, use a dedicated masonry saw or angle grinder with a diamond blade.
Which blade should I buy first?
A variety pack including a 6 TPI wood blade, a 10 TPI bi-metal (for nail-embedded wood), and a 24 TPI metal blade. Total investment: about $20. Covers 90% of homeowner reciprocating saw uses.
Is the tool-only version enough for a first-time buyer?
Only if you already own 24V POWERALL batteries. If this is your first Greenworks 24V tool, start with the drill kit and add this tool-only afterward.
