Bosch PROFACTOR 18V GSA18V-126 Reciprocating Saw
Bosch's current 18V flagship recip (it superseded the older GSA18V-125 Multi-Grip, which was pre-PROFACTOR). The GSA18V-126 pairs a BITURBO brushless motor with a 1-1/4 in stroke at up to 3,000 SPM, and layers on an electronics suite nobody else matches at this price: KickBack Control that halts the blade when it binds, adaptive speed control, end-of-cut detection, six speed settings, and a switchable orbital mode. Pro Tool Reviews scored it 9.3/10 and ranked it third of 11 saws tested.
Specifications
Features
Pros
- ✓Genuinely fast — placed third of 11 saws in Pro Tool Reviews' head-to-head cutting tests (9.46 s clean wood, 3.62 s PVC), right behind the class leaders.
- ✓KickBack Control stops the blade the instant it detects binding — a real safety edge over rivals when a blade catches overhead or in pipe.
- ✓Switchable orbital action speeds up wood demolition, while inline mode keeps metal cuts smooth — plus six speed settings to match the material.
- ✓Dual vibration dampening system earns praise for low fatigue in extended demo sessions.
- ✓Adaptive speed control and end-of-cut detection tame the saw at cut breakthrough, reducing blade whip.
- ✓Tool-free quarter-turn blade release and an adjustable shoe make blade swaps and depth management quick.
- ✓Folding rafter hook and LED work light are standard.
- ✓5-year warranty (with registration) is among the longest in the category, and it runs on any Bosch 18V/AMPShare pack.
Cons
- ✗No kit option in the US — bare tool only, so newcomers to Bosch 18V must buy CORE18V batteries and charger separately.
- ✗Needs high-output CORE18V (8.0Ah+) packs to unlock full BITURBO performance — older slim packs leave power on the table.
- ✗At 8.1 lbs bare / 10.25 lbs with an 8.0Ah battery, it's as heavy as some dual-battery 36V saws.
- ✗Street price of $279-$295 in mid-2026 is more than faster-selling rivals' bare tools.
- ✗Bosch's 18V ecosystem is much smaller at US home centers than DeWalt/Milwaukee/Makita, so batteries and deals are harder to find.
- ✗Very thin retailer review base (a handful of reviews at Lowe's) since its 2025 launch — long-term durability is unproven.
- ✗Electronics-heavy design (kickback, adaptive, end-of-cut sensors) is more that can go wrong out of warranty.
- ✗18.5 in length is on the long side for between-stud and tight-quarters work.

DeWalt's FlexVolt Advantage recip saw: it runs on any 20V Max battery but unlocks up to 50% more power when you snap on a FlexVolt pack. Tool Connect chip support adds jobsite asset tracking for fleets.

Makita's flagship LXT recip saw is an X2 tool: it gangs two 18V LXT packs for 36V of power (hence voltage listed as 36 — it still lives on the 18V LXT platform with no new charger or batteries needed). The 2-speed brushless motor drives a long 1-1/4 in stroke at up to 3,000 SPM, and a refined crank mechanism keeps vibration and blade deflection unusually low. Tool-less blade change, electric brake, XPT weather sealing, and an LED with preglow/afterglow round it out.

Makita's full-size 40V XGT recip saw, rated for 145 cuts in 2x10 SPF per 4.0Ah charge. Two speed ranges, an electric brake, and Makita's crank-balanced drivetrain aimed at all-day demolition.
