Your needs, this model
Does it fit your priorities?
Which saw is included in the 2625-21CT?
The exact manufacturer page lists the 2625-20 M18 HACKZALL. Its manual specifies 18-volt M18, 0–3,000 no-load SPM and a 3/4-inch stroke; CT marks a distinct package, not a new saw head.
Explore this need in the finder →What makes the 2625-21CT different from the 2625-21 kit?
The exact -21CT page lists compact M18 REDLITHIUM battery 48-11-1815. The exact -21 page lists XC extended-capacity battery 48-11-1828. Both pages list the same 2625-20 saw, 48-59-1812 charger and contractor bag; runtime is not inferred.
Does the compact-battery kit include a blade or hard case?
The exact -21CT In The Box list has four entries: saw, charger, compact battery and contractor bag. It does not list a blade or hard case, so confirm seller-added bundles separately.
Explore this need in the finder →Can the 2625-21CT satisfy a strict bare-tool weight limit?
The reviewed 2625-20 manual and manufacturer page do not state bare-tool weight. Compact format and a compact battery label are not numeric weight evidence for the saw.

Milwaukee's 2625-21CT is a distinct M18 HACKZALL kit built around the 2625-20 saw. The manufacturer page lists one saw, one M18/M12 multi-voltage charger, one M18 compact REDLITHIUM battery (48-11-1815) and one contractor bag. The related 2625-21 package instead lists an M18 XC extended-capacity battery (48-11-1828), while retaining the same saw, charger and bag. The model suffix is therefore a useful signal to verify before comparing package listings: two kits can share the saw while providing different battery families.
This page does not establish a specific runtime, number of cuts per charge or complete kit weight for either battery arrangement. “Compact” and “extended capacity” are Milwaukee's battery descriptions, and the part numbers identify what the official package page names. They do not justify a hands-on conclusion about how long the saw will run in wood, metal, PVC or overhead work. If the battery is the reason for choosing one SKU, confirm that the seller's written box list matches 2625-21CT and 48-11-1815.
The saw remains the 2625-20 HACKZALL
The included machine is not an updated cutting head: the exact page names the 2625-20. Milwaukee describes that model as a compact, one-handed reciprocating saw. Its operator manual lists an M18 18-volt supply, 0–3,000 no-load strokes per minute and a 3/4-inch stroke. Those specifications separate it from the full-size 2621-20, whose manual lists a 1-1/8-inch stroke, but they are not a controlled performance comparison. Tool format, blade geometry, stock and support all influence a real cut.
The manual describes a QUIK-LOK blade clamp for compatible 1/2-inch universal HACKZALL and SAWZALL blades, and the exact sources list an LED. Milwaukee describes a Dual Gear Anti-Vibration System, but no independent vibration or ergonomic test is available here. The exact model sources reviewed do not establish brushless motor type, a bare-tool weight, overall length, adjustable shoe, orbital mode or hang hook. The CT package changes the battery selection, not those saw-level facts.
Four items, with a soft bag
The official -21CT in-box list contains the 2625-20 saw, the 48-59-1812 charger, the 48-11-1815 compact M18 battery and a contractor bag. It does not list a hard case or a blade. That is different from the 2625-21's XC battery package, and it is different again from the 2625-20 tool-only SKU. A photo of a battery attached to the tool does not establish every item in the carton; the written itemized list and exact retail model are what settle the package record.
For someone who already has compatible M18 equipment, the practical question is whether the compact battery is useful as a second pack or whether the kit duplicates charger and battery equipment. For someone starting with no M18 components, the package includes both a battery and charger, but it still does not document a blade or hard case. No conclusion about total cost or retailer availability is made here; compare the actual SKU and box list rather than assume that a particular listing is current or complete.
Blade setup is still part of the decision
The manual instructs the user to remove the battery before changing the blade, confirm that the blade is locked, use a blade at least 3-1/2 inches long and keep the shoe flat against the work. It warns that the blade must project far enough beyond the shoe and workpiece for the stroke. These are specific instructions for the included 2625-20. A one-handed saw still needs secure workpiece support and a controlled grip; compact size does not make a difficult, unstable or overhead cut safe by itself.
Before a blind or plunge cut, the manual calls for checking for hidden wiring, gas lines and water pipes. Select a blade for the material and cut shape, secure the material, and use suitable eye and other protective equipment. The package's battery choice may change the user's preferred setup, but neither battery size nor the maker's anti-vibration label replaces safe blade contact and work support.
Choosing between 2625-21CT and 2625-21
The -21CT is a useful candidate when the buyer specifically wants the compact-battery HACKZALL kit and accepts a contractor bag rather than a hard case. The -21 offers a different documented battery family, while the -20 omits both battery and charger. Those facts support package comparison without implying that one option will cut faster, run for a known duration or feel lighter in use. Anyone who requires a measured tool weight, an adjustable pivot shoe, orbital action, a built-in hook or a blade in the box should not treat those fields as established.
Check the suffix carefully, and if package identity matters, verify the battery part number and the four listed items with the seller. This research-based evaluation uses the exact 2625-21CT product page and the exact 2625-20 manual. No saw was used, owned or independently tested, and no weight, vibration, runtime or cutting measurement is claimed.
