A Sawzall saw is a brand name for a type of reciprocating saw. This powerful power tool for cutting moves its blade back and forth very fast. People often call any reciprocating saw a Sawzall, even if it is made by another company. It is best known as a demolition saw because it is great for taking things apart quickly.
Deciphering the Sawzall: More Than Just a Name
The term “Sawzall” is actually a registered trademark owned by the Milwaukee Tool company. However, like “Kleenex” for tissues or “Band-Aid” for adhesive bandages, the name has become a common, generic term for this specific type of saw.
What Makes a Reciprocating Saw Unique?
The key feature of a Sawzall is its cutting action. Unlike a circular saw that spins, this tool uses a piston-like motion. The blade pushes forward and pulls back repeatedly. This rapid back-and-forth movement is called reciprocation.
This action makes the reciprocating saw very versatile. It can cut through many different materials. It is a staple for construction workers, remodelers, and even homeowners doing tough cleanup jobs. It acts as a true portable demolition tool.
Key Components of a Sawzall
To grasp how a Sawzall works, look at its main parts:
- Motor Housing: Contains the powerful motor. Models come in corded or cordless versions (the cordless reciprocating saw offers great freedom).
- Grip and Handle: Designed for holding the tool firmly, often with vibration dampening.
- Blade Clamp: This mechanism securely holds the cutting blade in place.
- Shoe (or Blade Support): A metal plate at the front that rests against the material being cut. This helps keep the cut straight and controls the depth.
- Trigger and Speed Control: Allows the user to control the reciprocating saw speed to match the material.
Primary Uses of the Sawzall Saw
The Sawzall excels in situations where precision cutting is less important than speed and brute force. Its ability to cut in tight spaces where a circular saw cannot reach adds to its appeal.
Demolition Work
This is where the Sawzall truly shines. It is the go-to demolition saw for tearing down structures or old fixtures.
- Taking Down Walls: Cutting through studs, drywall, and old nails quickly.
- Plumbing and HVAC: Cutting through old pipes made of copper, plastic, or cast iron.
- Removing Fixtures: Cutting apart old sinks, cabinets, or door frames embedded with fasteners.
Remodeling and Renovation
When modifying an existing structure, the Sawzall becomes indispensable.
- Cutting Openings: Making rough cuts for new windows or doors in existing framing.
- Trimming Branches: With the right blade, it can prune large, thick tree limbs too big for loppers.
- Exposed Nail Removal: Cutting off the heads of stubborn, set-in nails when separating wood pieces.
Utility and Emergency Work
Firefighters and rescue teams often carry powerful reciprocating saws. They are fast and effective for gaining access in emergency situations.
- Vehicle Extraction: Specialized blades can cut through car frames quickly.
- Emergency Entry: Breaching doors or thin walls when time is critical.
Exploring Features: What to Look For in a Buyer’s Guide
Choosing the right Sawzall depends on what you plan to cut and how often you plan to use it. Modern tools offer features that greatly affect performance and comfort.
Corded vs. Cordless Operation
This is the first big decision when selecting your power tool for cutting.
| Feature | Corded Model | Cordless Model (Cordless Reciprocating Saw) |
|---|---|---|
| Power Supply | Wall outlet (AC Power) | Rechargeable battery (DC Power) |
| Power Output | Generally more consistent and higher sustained power. | Power can drop as the battery drains. Modern lithium-ion batteries are very strong. |
| Mobility | Limited by cord length and need for power access. | Excellent mobility for remote jobs or high-up work. |
| Weight | Often lighter, as they lack a heavy battery pack. | Heavier due to the battery, though balanced well. |
| Best For | Continuous, heavy-duty work in a shop setting. | On-site demolition, remote locations, or intermittent use. |
Stroke Rate and Stroke Length
These two factors determine how fast and how deeply the saw can cut.
Reciprocating Saw Speed (Stroke Rate)
This is measured in Strokes Per Minute (SPM). Higher SPM means faster cutting, especially in softer materials like wood. Many quality saws allow you to adjust the reciprocating saw speed with the trigger.
- Low Speed (0–1500 SPM): Best for metal, thick plastic, or when starting a cut precisely.
- High Speed (2000+ SPM): Ideal for fast cutting through wood or drywall.
Stroke Length
This is how far the blade travels back and forth in one cycle.
- Longer Stroke Length (e.g., 1 1/8 inches): Removes more material with each stroke. This is preferred for fast demolition saw work in wood.
- Shorter Stroke Length (e.g., 3/4 inch): Offers better control and is better for cutting metal or working in tight spaces.
Orbital Action Saw Feature
Some advanced models offer an orbital action saw setting. This is a key differentiator.
When a reciprocating saw is set to orbital action, the blade moves slightly forward on the cutting stroke rather than just straight back and forth. This adds a small scooping or tearing motion.
- Benefit: Significantly speeds up cutting in wood by chewing through fibers faster.
- Drawback: It creates a rougher cut finish and increases vibration. It is generally not used for fine work or cutting metal.
Blade Changes and Shoe Adjustment
Look for a tool with a tool-less blade change system. You should be able to swap blades quickly without needing an Allen wrench, especially important on a job site.
The shoe should also be adjustable. Being able to pivot the shoe allows the saw to maintain better contact with the material, which stabilizes the cut and reduces vibration transferred to the user.
Blade Types for Sawzall: The Real Key to Versatility
A Sawzall is only as good as the blade attached to it. Since this tool is designed to cut everything from wood and nails to tile and cast iron, you need specialized blade types for Sawzall.
Using the wrong blade can damage the tool, waste time, or be dangerous.
Wood Cutting Blades
These blades are thick and designed to handle high speeds and resist breakage when hitting embedded screws or nails.
- Standard Wood: Coarse teeth for fast, rough removal.
- Wood with Nails: Feature fewer, tougher teeth made from bimetal or carbide-tipped material. These are essential for demolition work.
Metal Cutting Blades
These blades have much finer teeth and are often made of high-speed steel (HSS) or bimetal (a combination of flexible metal and a harder cutting edge).
- Thin Sheet Metal: High TPI (Teeth Per Inch) blade to prevent snagging.
- Thick Pipe/Steel Bar: Lower TPI blade to allow for better chip removal and prevent overheating.
Specialty Blades
For jobs outside of standard wood and metal, specialized blades are necessary:
- Carbide-Tipped Blades: The toughest option. They use small pieces of super-hard carbide brazed onto the steel body. These are necessary for cutting brick, mortar, cement board, and even some cast iron. They last much longer but cut slower than standard bi-metal blades.
- Reciprocating Tile Blades: Often diamond-coated. Used for cutting ceramic or porcelain tile during plumbing or bathroom renovations.
Understanding TPI (Teeth Per Inch)
TPI directly affects the cut:
- Low TPI (6–10 TPI): Faster cutting, rougher finish. Best for soft materials or demolition.
- High TPI (14–32 TPI): Slower cutting, smoother finish. Best for thin metals or precision work.
Power and Performance: Focusing on Brands
While many companies make great reciprocating saws, the name Milwaukee Sawzall holds a special place due to its long history and reputation for durability.
The Legacy of Milwaukee Sawzall
Milwaukee pioneered this tool category. Their commitment to heavy-duty design means their tools are often built to withstand the daily abuse of professional job sites. Modern Milwaukee Sawzall models frequently feature brushless motors, which increase efficiency and battery life in their cordless reciprocating saw lines. They often set the benchmark for maximum stroke length and power delivery.
Other Top Contenders
While Milwaukee dominates the branding, other companies offer excellent performance:
- DeWalt: Known for rugged construction and good battery integration across their tool platforms.
- Makita: Often praised for lightweight design and excellent ergonomics, which reduces fatigue during long use.
- Bosch: Offers innovative features, sometimes including anti-vibration technology, making extended use more comfortable.
When comparing, always check the quoted SPM and stroke length against the expected workload. A high-powered saw is necessary if you plan to use it as a primary demolition saw regularly.
Operation Tips for Safety and Efficiency
Handling a Sawzall safely is crucial because of its high power and aggressive action. It generates significant vibration and torque.
Safety First
- Wear Protection: Always wear safety glasses. Debris flies everywhere when operating a power tool for cutting. Gloves help manage vibration.
- Secure Your Material: Never try to hold the material with one hand while cutting with the Sawzall in the other. Use clamps or vises to secure the workpiece firmly. If the material binds, the tool can kick back violently.
- Use Both Hands: Grip the tool firmly with both hands whenever possible to control the vibration and torque, especially when starting a cut or using orbital action saw settings.
- Let the Tool Do the Work: Do not force the saw. Pushing too hard overheats the motor and dulls the blade quickly. Allow the tool’s weight and speed to guide the cut.
Starting Cuts Cleanly
Starting a cut requires finesse, especially on hard surfaces like metal or when you need precision.
- For Metal or Plastic: Use a low reciprocating saw speed. Start the saw just touching the material and slowly move the trigger to increase speed until the blade bites.
- Using the Shoe: Rest the shoe firmly on the surface before engaging the trigger. This stabilizes the blade and prevents “walking” or skittering across the surface.
- Plunge Cutting: For cutting a hole in the middle of a sheet (like drywall or plywood), start the saw at an angle before slowly bringing the blade flat onto the surface to begin the plunge cut.
Maintenance for Longevity
A well-maintained Sawzall will last much longer and perform better.
Blade Care
Blades are disposable, but extending their life is important:
- Clean Blades: After cutting materials that leave residue (like asphalt shingles or sticky plastics), wipe the blade clean.
- Replace Dull Blades: A dull blade forces the motor to work harder, leading to overheating and poor performance. Never hesitate to swap out a blade that feels like it is struggling.
Tool Maintenance
- Check the Shoe: Ensure the shoe is free of dents or deep scratches that could impede smooth contact with the work surface.
- Lubrication Points: Check your manual for any lubrication points, though most modern tools are largely sealed.
- Battery Health (For Cordless): Store cordless reciprocating saw batteries in a climate-controlled area, not in extreme heat or cold, to maximize lifespan.
Frequently Asked Questions (FAQ)
Can I use a Sawzall to cut concrete?
Yes, but you must use a specialized, heavy-duty carbide-tipped or diamond-grit blade. Standard wood or metal blades will break instantly and are dangerous to use on masonry. Concrete cutting is very demanding on the saw motor.
What is the difference between a Sawzall and a jigsaw?
A jigsaw moves its blade up and down in a straight line for fine, curved cuts in thin wood or plastic. A Sawzall (reciprocating saw) moves its blade back and forth aggressively over a longer distance, designed for heavy-duty, rough cutting in demolition.
Why does my reciprocating saw vibrate so much?
Vibration is inherent to reciprocating motion. However, excessive vibration usually points to:
1. A low-quality or worn-out blade.
2. Improper technique (pushing too hard).
3. Worn internal components (especially if it’s an older tool). Look for tools advertising advanced anti-vibration features if this is a major concern.
How do I adjust the orbital action saw setting?
The control for orbital action is usually a separate switch or dial near the blade collar or trigger assembly, often marked with symbols representing straight cutting and orbital cutting. Consult your specific tool’s manual to locate this feature.
What is the ideal reciprocating saw speed for cutting PVC pipe?
For PVC pipe, a medium to high reciprocating saw speed (around 2,000 SPM) works well with a coarse-toothed wood blade. This allows the blade to quickly chew through the plastic without melting it excessively, which can happen at very high speeds.
