Key Features to Look For in a Sawzall

Beyond the corded/cordless and M12/M18 distinctions, several features significantly impact a Sawzall’s performance, comfort, and versatility.

Ignoring these is like buying a car without checking the engine or safety features.

Stroke Length and Strokes Per Minute SPM

These two metrics are fundamental to a Sawzall’s cutting efficiency.

• Stroke Length: This refers to how far the blade moves back and forth with each stroke.
  • Impact: A longer stroke length e.g., 1-1/8 inches to 1-1/4 inches means the blade removes more material with each pass. This translates to faster cutting, especially in thicker materials like dimensional lumber, pipes, or layered demolition. Shorter stroke lengths e.g., 1/2 inch to 3/4 inch found on some compact models are often preferred for finer cuts, metal cutting where blade heat needs to be managed, or in very tight spaces where a long stroke might bind.
  • Milwaukee Example: The M18 FUEL SAWZALLs 2720-20, 2821-20 boast a full 1-1/4 inch stroke length, contributing significantly to their aggressive cutting speed. M12 HACKZALLs might have a shorter 1/2 or 5/8 inch stroke.
• Strokes Per Minute SPM: This is the speed at which the blade moves back and forth.
  • Impact: Higher SPM e.g., 0-3,000 SPM generally means faster cutting, particularly in softer materials or for making quick, rough cuts. However, for certain applications like cutting metal, a lower SPM with controlled pressure can be more effective to prevent overheating the blade and extending its life. Variable speed triggers are crucial here.
  • Milwaukee Example: Most Milwaukee Sawzalls offer a variable speed trigger, allowing you to match the SPM to the material. The M18 FUEL models typically top out around 3,000 SPM.

Vibration Control and Ergonomics

Cutting through tough materials with a powerful reciprocating saw can generate significant vibration, leading to user fatigue and reduced control.

Milwaukee has invested heavily in technologies to mitigate this.

• Anti-Vibration Technology:
  • How it Works: Often involves counterbalancing mechanisms, internal dampeners, or isolated motor/gearbox designs that absorb or redirect vibrations before they reach your hands.
  • Impact: Less vibration means less fatigue, allowing you to work longer and more comfortably. It also translates to better control over the tool, leading to more accurate cuts and reduced kickback.
  • Milwaukee Example: The M18 FUEL SAWZALLs, especially the newer Milwaukee M18 FUEL SAWZALL Reciprocating Saw 2821-20, incorporate advanced vibration reduction. The 2821-20 specifically features a “geared anti-vibration mechanism” that delivers what Milwaukee claims is the lowest vibration in its class.
• Ergonomics:
  • Design: This includes the grip design rubber overmold for comfort and slip resistance, weight distribution, and overall balance of the tool. A well-balanced Sawzall feels lighter and is easier to maneuver, especially during extended use or overhead work.
  • Impact: Good ergonomics reduce strain on your hands, wrists, and arms, preventing muscle fatigue and making the tool feel like an extension of your body, rather than a wrestling partner.
  • Milwaukee Example: Milwaukee’s Sawzalls typically feature excellent overmolding and designs that aim for balance. The compact nature of the M12 HACKZALLs contributes to their superior ergonomics for one-handed use.

Motor Technology Brushed vs. Brushless vs. FUEL

The type of motor is a significant differentiator in modern power tools, especially cordless ones.

• Brushed Motors:
  • Characteristics: Older technology, uses carbon brushes that wear down over time and create friction/heat.
  • Impact: Less efficient, generates more heat, requires brush replacement, and delivers less power relative to their size. Found on entry-level or older models.
  • Milwaukee Example: The older Milwaukee M18 SAWZALL 2621-20 and Milwaukee M12 HACKZALL 2420-20 use brushed motors. Still capable, but not optimized for peak performance or longevity compared to brushless.
• Brushless Motors:
  • Characteristics: No carbon brushes, uses electronic commutators to reverse magnetic fields.
  • Impact: Significantly more efficient, runs cooler, longer motor life, and delivers more power and run time per battery charge.
  • Milwaukee Example: This is the core of Milwaukee’s “FUEL” technology.
• Milwaukee FUEL Technology:
  • Characteristics: This isn’t just a brushless motor. it’s a system that integrates three key components:
    1. POWERSTATE™ Brushless Motor: Designed and built by Milwaukee, these are purpose-built for each tool, maximizing power and efficiency.
    2. REDLINK PLUS™ Intelligence: Advanced electronics that provide optimal performance and overload protection, communicating constantly between the tool, battery, and charger. This is the “brain” that optimizes everything.
    3. REDLITHIUM™ Battery Pack: Milwaukee’s proprietary battery technology, optimized for performance, run time, and durability in harsh conditions.
  • Impact: The synergy of these three components delivers what Milwaukee calls “corded performance in a cordless tool.” This means faster cutting, longer run times, and extended tool life compared to standard brushed or even basic brushless tools.
  • Milwaukee Example: The Milwaukee M18 FUEL SAWZALL 2720-20 and Milwaukee M18 FUEL SAWZALL 2821-20 are prime examples of FUEL technology at work, offering industry-leading performance.

When choosing, prioritizing a FUEL model, especially for M18, is a no-brainer if performance and longevity are important to you.

It’s an investment that pays dividends in productivity and durability, much like investing in a high-quality education or a robust business strategy.

It’s like having a dedicated tool for every step of a complex project, rather than trying to hammer a screw.

Effective Cutting Techniques

Even with the best Sawzall and blade, technique plays a crucial role in safety, speed, and blade longevity.

• Maintain Firm Grip and Stance: Always hold the tool with both hands unless using a HACKZALL designed for one-handed use and maintain a stable, balanced stance. This helps control kickback and ensures a straight cut.
• Let the Tool Do the Work: Don’t force the saw. Excessive downward pressure not only exhausts you but also binds the blade, generates heat, and drastically reduces blade life. Allow the tool’s power and the blade’s teeth to cut. Push only enough to keep the teeth engaged.
• Orbital Action if available: Some high-end Sawzalls like the corded SUPER SAWZALL have an orbital action setting. This moves the blade slightly forward on the cutting stroke and back on the return stroke, making for faster, more aggressive cuts in wood and soft materials. Turn it off for metal or precision cuts.
• Vary Blade Depth/Angle: When cutting through thick material, don’t try to go straight through in one go. Rock the saw slightly, or use a “plunge cut” technique where you start on the edge and then pivot into the material to get the blade started. Adjust the shoe depth to expose fresh teeth on the blade and maximize blade life.
• Manage Heat:
  • Metal Cutting: When cutting metal, especially thicker pieces, apply cutting fluid or oil to cool the blade and workpiece. This prevents premature blade dulling and workpiece discoloration.
  • Avoid Overheating: If you see smoke or the blade turns blue, you’re generating too much heat. Ease up on pressure, consider a different blade, or allow the blade to cool.
• Secure Your Workpiece: Always clamp or secure the material you’re cutting. A moving workpiece is dangerous and leads to poor cuts. Use clamps, vises, or even your foot if safe and necessary.
• Flush Cutting: For cutting pipes or nails flush with a surface, invert the blade so the teeth face upwards, and use the shoe as a guide against the surface. Milwaukee also makes dedicated flush-cut blades.
• Safety First: Always wear appropriate Personal Protective Equipment PPE, including safety glasses, hearing protection, and gloves. Be aware of your surroundings, especially what’s behind your cut. Reciprocating saws are powerful and can cause significant damage if used carelessly.

By mastering blade selection and cutting techniques, you transform your Milwaukee Sawzall into an even more efficient and indispensable tool, ensuring you get the most out of your investment.

• Proper Storage: Store your Sawzall in a dry, cool place, away from direct sunlight and extreme temperatures. Using a tool bag or case not only keeps it clean but also protects it from impacts. For cordless models, store batteries partially charged around 50% for long-term storage to maximize their lifespan, and avoid storing them in extreme heat or cold.

Blade Clamp and Shoe Maintenance

These are critical components that directly impact cutting performance and safety.

• Blade Clamp Inspection: Regularly inspect the blade clamp mechanism. Ensure it’s clean and free of rust or stuck debris. A faulty blade clamp can cause blades to wobble, break, or even fly out, which is extremely dangerous. If the mechanism feels stiff or sticky, a small amount of dry lubricant like PTFE spray can help, but avoid grease which can attract dust.
• Shoe Adjustment: The adjustable shoe is designed to maximize blade life by allowing you to use different sections of the blade’s teeth. Ensure the adjustment mechanism moves freely and locks securely in place. Keep the shoe itself clean, as debris can build up underneath and hinder smooth gliding.
• Blade Condition: Always use sharp, undamaged blades. A dull blade forces the saw to work harder, drains batteries faster, and increases vibration and heat. A bent or chipped blade can cause dangerous kickback. Dispose of worn blades responsibly.

Motor and Gearbox Care

While these are largely sealed units on modern Milwaukee Sawzalls, there are still best practices.

• Avoid Overloading: Don’t continuously push the tool beyond its limits. If the motor sounds strained or the tool heats up excessively, ease off. Overloading can lead to premature motor wear and failure.
• Listen for Unusual Noises: Grinding, whining, or rattling sounds can indicate issues with the gears, bearings, or motor. If you hear unusual noises, stop using the tool and have it inspected by a Milwaukee authorized service center. Trying to fix complex internal issues yourself without proper training can lead to further damage or unsafe operation.
• Battery Health Cordless Models: Use genuine Milwaukee REDLITHIUM batteries and chargers. Counterfeit or off-brand batteries can damage your tool, provide sub-par performance, and pose safety risks. Follow recommended charging practices – don’t overcharge or deep discharge frequently.

By following these maintenance tips, your Milwaukee Sawzall, whether it’s a mighty corded SUPER SAWZALL or a nimble M12 HACKZALL, will remain a reliable and powerful tool for years to come. It’s all about respecting your tools.

• Dust Mask/Respirator: When cutting dusty materials drywall, wood, concrete, a dust mask or respirator is crucial to protect your lungs from airborne particles.
• Appropriate Clothing: Wear close-fitting clothing. Avoid loose sleeves, jewelry, or anything that could get snagged by the blade or moving parts. Sturdy, closed-toe shoes with good grip are also advisable.

Workpiece Security

This is perhaps the most critical safety tip outside of PPE.

A workpiece that moves unexpectedly can cause serious injury or damage.

• Clamp It Down: Whenever possible, secure the material you’re cutting with clamps, vises, or other fastening devices.
• Stable Surface: Ensure your workpiece is on a stable, level surface that won’t shift or collapse during the cut.
• Identify Pinch Points: Before cutting, identify potential pinch points where the material might bind or collapse, trapping the blade. Adjust your cut strategy accordingly.

Tool Control and Awareness

The Sawzall is powerful. you need to be in control at all times.

• Two-Handed Grip: Always use a firm, two-handed grip on the Sawzall unless it’s a compact HACKZALL designed for one-handed use. This provides maximum control and helps manage kickback.
• Proper Stance: Maintain a balanced, stable stance with your feet shoulder-width apart. Avoid awkward positions.
• Let the Blade Stop: Never set the tool down until the blade has come to a complete stop.
• Identify Hidden Obstacles: Before cutting into walls, floors, or ceilings, always check for hidden electrical wires, plumbing pipes, gas lines, or other utilities. Use a stud finder with metal detection capabilities or consult blueprints. Cutting into live electrical wires or gas lines can be catastrophic.
• Beware of Kickback: Kickback occurs when the blade binds in the material, causing the saw to unexpectedly jump back towards the user.
  • Prevention: Use sharp blades, avoid forcing the cut, maintain a firm grip, and ensure the workpiece is secure.
  • Recovery: If kickback occurs, maintain your grip and control, and release the trigger immediately.
• Mind the Blade Path: Always be aware of where the blade will exit the material and what’s behind it. Ensure there are no people, sensitive materials, or power lines in the blade’s path.

Electrical Safety Corded Models

For corded Sawzalls, electrical safety is paramount.

• Inspect Cord: Before each use, check the power cord for any damage cuts, abrasions, exposed wires. If damaged, do not use the tool. have it professionally repaired.
• Use GFCI Outlets: Always plug corded tools into a Ground Fault Circuit Interrupter GFCI outlet, especially when working in damp or outdoor conditions.
• Extension Cords: If using an extension cord, ensure it’s rated for outdoor use if applicable and has the correct gauge for the tool’s amperage to prevent voltage drop and overheating.

By internalizing these safety practices, you not only protect yourself but also everyone around you on the job site.

A safe worker is an efficient worker, and it’s a testament to your professionalism.
