Key Features
Fast One-Handed CuttingThe Milwaukee 2719-21 M18 FUEL HACKZALL Reciprocating Saw Kit is built to cut faster than typical one-handed reciprocating saws. Its 7/8 in. stroke length removes more material per pass, which helps you finish demo and rough-in cuts quicker. Lower Vibration ControlThe dual gear counter balance system cuts vibration by up to 4x versus traditional reciprocating saws. That means smoother cut starts in metal and better control when you are working one-handed or overhead. M18 System FitThis kit runs on the Milwaukee M18 battery platform and includes a 5.0Ah battery and multi-voltage charger. If you are already on M18, it drops right into the system and keeps your cordless setup simple.
Overview
The Milwaukee 2719-21 M18 FUEL HACKZALL Reciprocating Saw Kit is a cordless one-handed reciprocating saw kit built for fast demolition, rough-in cutting, and tight-space work. This is a reciprocating saw designed for one-handed cutting in wood, metal, and overhead applications. Model Number 2719-21. If you need a saw that is easier to control than a full-size reciprocating saw but still has real cutting speed, this is the one Milwaukee built for that job.
What makes this saw matter on the job is how it balances speed with control. Milwaukee pairs a POWERSTATE brushless motor with a 7/8 in. stroke length, and that combination is why it cuts aggressively for a compact saw. The longer stroke removes more material with each pass, so when you are trimming studs, cutting pipe, or making quick service cuts, you spend less time leaning on the trigger waiting for the blade to catch up.
The one-handed design is not just about convenience. It changes where and how you can work. In wall cavities, between studs, above shoulder height, or anywhere a full-size saw feels clumsy, the HACKZALL format gives you better access and better balance. Milwaukee specifically calls out easier cutting in tight spaces and overhead applications, and the compact body backs that up. For electricians, plumbers, remodelers, and service crews, that is the difference between getting the cut done cleanly or wrestling the tool the whole time.
Milwaukee also built this M18 FUEL HACKZALL around lower vibration, which is a bigger deal than it sounds on a reciprocating saw. The dual gear counter balance mechanism is designed to deliver up to 4x lower vibration than traditional reciprocating saws. In plain terms, that means smoother cut starts, less bucking when the blade first hits the material, and less fatigue when you are making repeated cuts through pipe, nail-embedded wood, or framing members.
Jobsite durability and electronics are part of the package here too. REDLINK PLUS intelligence manages communication between the tool, battery, and charger to optimize performance and protect against overload, overheating, and over-discharge. Milwaukee also calls out a rubber seal and weep holes for added protection against water and debris. That matters for anyone using a cordless reciprocating saw in dusty remodel spaces, damp service environments, or outdoor punch-list work where tools do not stay clean for long.
As a kit, this setup gives you a practical starting point or an easy add-on to an existing cordless platform. It includes one M18 XC5.0 REDLITHIUM battery pack, an M18/M12 multi-voltage charger, and a contractor bag. The saw is part of the Milwaukee M18 battery system, so it fits into a large cordless lineup if you already run M18 tools. That platform compatibility is a real advantage for crews trying to keep batteries, chargers, and trucks organized.
From a size and weight standpoint, the numbers are right where you want them for a compact cutting tool. The saw weighs 4.07 lbs without the battery and 5.57 lbs with the battery installed, with an overall length of 16.3 in. That keeps it portable enough for service work and overhead cuts without giving up the runtime benefit of the included 5.0Ah pack.
Who should buy it? If you want a compact reciprocating saw for demolition, pipe cutting, framing cut-ins, and tight access work, this kit makes a lot of sense. It is especially well suited for plumbers, electricians, remodelers, HVAC techs, punch-out crews, and general contractors who need a cordless saw that is easy to grab, easy to control, and fast enough that it does not feel like a compromise.
Milwaukee 2719-21 M18 FUEL HACKZALL Reciprocating Saw Kit in Tight Framing Spaces
This is where a one-handed reciprocating saw earns its keep. The compact body gives you the control to work between studs and around existing rough-ins without dragging a larger saw into the opening.
- Compact design is built for tight spaces
- One-handed layout improves access in framed walls and service openings
Smoother Starts Overhead
Overhead cuts get tiring fast if the saw bucks around. Milwaukee’s lower-vibration design helps the blade start cleaner and keeps the tool more manageable when you are reaching up into joists, rafters, or blocking.
- Up to 4x lower vibration than traditional reciprocating saws
- Designed for smoother cut starts and reduced fatigue
Built for Fast Rough-In and Demo Cuts
For pipe, conduit, and general demolition work, speed matters. The brushless motor and 7/8 in. stroke length help the saw cut aggressively without giving up the compact feel that makes the HACKZALL platform useful.
- POWERSTATE brushless motor is built for cutting speed and power
- 7/8 in. stroke length removes more material with each stroke
