The Milwaukee M12 FUEL HACKZALL Reciprocating Saw is Milwaukee's compact 12V one-handed reciprocating saw for service work, punch-list tasks, and tight-space cutting. Milwaukee describes it as the fastest cutting and most powerful saw in its class, with a POWERSTATE Brushless motor, compact layout, and light weight that make overhead cuts easier to manage. Compared with the M18 HACKZALL, this model trades outright platform power for lower size and weight while staying within the M12 FUEL line. It is a practical choice for users who already own M12 batteries and want a more compact recip saw than a full-size two-handed SAWZALL.
Does the 2520-20 include a battery or charger?
No. The 2520-20 is the tool-only version, so M12 batteries and charger are sold separately.
How compact is the 2520-20?
Milwaukee lists it at 11 in. long, 7 in. high, 2.75 in. wide, and 3.2 lb. That makes it notably smaller and lighter than a full-size reciprocating saw.
Is the 2520-20 meant for one-handed use?
Yes. The HACKZALL format is designed around one-handed control and tighter-space access, which makes it useful for service and overhead cutting.
How does it compare with the M18 HACKZALL?
The M12 version is smaller and lighter, while the M18 version is the stronger platform for tougher cutting. The better choice depends on whether compact size or higher-output runtime matters more to you.
Is this part of the M12 FUEL platform?
Yes. It is an M12 FUEL tool using Milwaukee's POWERSTATE Brushless motor, and it is compatible with the M12 battery system.
Who is the 2520-20 best for?
It is a strong fit for technicians, remodelers, and homeowners who already own M12 batteries and want a compact recip saw for light demolition, trimming, and tight-space cuts.
