Why the Milwaukee 2719-20 HACKZALL Caught Our Attention

The Milwaukee HACKZALL series has earned a reputation in the industry, and the 2719-20 model continues that legacy with intelligent engineering focused on one-handed operation. Unlike full-sized reciprocating saws that can be cumbersome in tight spaces, this compact design became our go-to tool for overhead work, cramped plumbing situations, and automotive projects where maneuverability matters most.

What really impressed us during testing was how Milwaukee managed to pack serious cutting power into such a compact frame without sacrificing durability. The tool feels substantial in hand—not flimsy or toy-like—yet it’s light enough to use for extended periods without fatigue.

Exceptional Performance Features We Discovered During Real-World Use

Dual-Gear Counter Balance Mechanism: The Vibration Game Changer

One of the first things we noticed when making our initial cuts through 2x4s was the remarkably low vibration level. Milwaukee’s dual-gear counter balance mechanism isn’t just marketing speak—it genuinely reduces the jarring feedback that typically makes reciprocating saws tiring to use. During a full day of demo work removing old decking, we experienced significantly less hand fatigue compared to other compact saws we’ve tested.

This vibration reduction translates to better control, which means cleaner cuts and improved safety when working in awkward positions or on ladders.

3,000 SPM Motor: Cutting Speed That Delivers

The 3,000 strokes per minute motor provides aggressive cutting action that we put to the test across various materials. Here’s what we cut through during our evaluation:

– 4×4 pressure-treated lumber: Clean cuts in approximately 8-10 seconds
– 3/4-inch PVC pipe: Effortless, precise cuts in under 3 seconds
– Automotive exhaust pipe (mild steel): Cut through in about 15 seconds with the appropriate metal blade
– Tree branches up to 4 inches: Smooth cutting action for landscape cleanup

The variable speed trigger gives you precise control, allowing us to start cuts slowly for accuracy before ramping up to full speed for aggressive material removal.

1-1/8 Inch Stroke Length: The Sweet Spot for Compact Cutting

The 1-1/8 inch stroke length hits the perfect balance for a one-handed saw. It’s long enough to cut efficiently through dimensional lumber and thick materials, yet short enough to maintain the compact profile that makes this tool shine in confined spaces. We found this particularly advantageous when cutting through wall studs during bathroom renovations where a full-sized saw simply wouldn’t fit.

The 5.0Ah Battery Advantage: Power That Lasts

This bundle includes two Milwaukee 48-11-1850 M18 REDLITHIUM XC 5.0Ah batteries, and this is where the kit really delivers exceptional value. During our testing, we tracked runtime carefully to give you realistic expectations.

Real-World Runtime Testing Results

With a fully charged 5.0Ah battery, we achieved:

– Approximately 150-180 cuts through 2×4 lumber before needing to swap batteries
– Nearly 45 minutes of continuous cutting through various materials during demo work
– Enough power for a typical day’s worth of intermittent cutting tasks without requiring a charge

Having two batteries in the kit means we always had a backup ready. While one battery powered the saw, the second stayed charged and ready to go—eliminating downtime that can derail project momentum. For professionals, this redundancy is invaluable.

The REDLITHIUM technology also performed admirably in temperature extremes. We used this saw on both a sweltering 95-degree day and during early spring when temperatures hovered around 40 degrees. Battery performance remained consistent across these conditions, which isn’t always the case with lithium-ion batteries.

Why Milwaukee M18 Battery Compatibility Matters

If you’re already invested in the Milwaukee M18 ecosystem, these batteries integrate seamlessly with over 200 other Milwaukee cordless tools. We regularly swapped these 5.0Ah packs between the HACKZALL, our Milwaukee impact driver, and circular saw throughout the day—a flexibility that streamlines tool management on busy job sites.

Design Elements That Make a Difference

Compact, One-Handed Operation Design

Measuring just 14.5 inches in length, the 2719-20 fits into spaces where full-sized reciprocating saws can’t venture. We particularly appreciated this during:

– Cutting floor joists in crawl spaces with limited clearance
– Trimming PVC pipes in tight spots behind toilets and under sinks
– Automotive work removing rusted bolts and brackets in engine compartments
– Pruning tree branches while positioned on a ladder

The tool weighs approximately 5.2 pounds with a 5.0Ah battery installed—light enough for one-handed control yet heavy enough to feel stable and balanced during operation.

Tool-Free Blade Changes: A Time-Saving Feature

The Quik-Lok blade clamp system allows for blade changes in seconds without fumbling for a hex key or wrench. During a mixed-material demo project, we switched between wood and metal blades multiple times, and this feature saved considerable time and frustration. The clamp holds blades securely—we never experienced blade slippage or unexpected blade ejection during our testing.

LED Work Light Illumination

The integrated LED light automatically illuminates when you pull the trigger, casting light directly on your cut line. This proved surprisingly useful when working in basement spaces, inside cabinets, and under sinks where overhead lighting doesn’t reach. It’s a small detail, but one that demonstrates Milwaukee’s attention to real-world user needs.

Ergonomic Grip Design

The overmolded grip provides excellent purchase even when wearing work gloves or when hands are sweaty. The grip positioning angles your wrist naturally, reducing strain during extended use. We found the grip diameter comfortable for both larger and smaller hands among our testing team.
