Flex Tools
Flex has 5 tools on RankMyTool, priced from $159 to $299. The highest-rated Flex pick is the Flex 24V FX2141 Circular Saw at 4.8★. Compare the full lineup below.
Flex's 24V in-line sidewinder is one of the sleeper hits of the cordless saw world: 5,800 RPM, a 2-5/8 in depth of cut that clears 3x lumber in one pass, and Pro Tool Reviews' 9.5/10 'elite cutting performance' verdict. The balanced in-line design gives a clear view down both sides of the blade, and with a 10.0Ah Stacked Lithium pack Flex claims up to 610 cuts in 2x4 lumber. Magnesium footplate and guards keep it durable without the bulk.
The FX1371A is Flex's flagship 24V hex impact driver, released in early 2022 as part of the brand's Stacked Lithium generation. Its brushless motor produces 2,500 in-lbs of torque with three speed modes topping out at 4,000 RPM and 4,450 IPM, plus two self-tapping screw modes that detect torque changes and stop before stripping. The signature Quick Eject collet has an eject button above the trigger so bits can be inserted and released with one hand.
The FX1272T is Flex's second-generation 24V flagship hammer drill, replacing the FX1271T in 2026 after five years and raising output to 1,500 in-lbs, 3,000 RPM, and 48,000 BPM with its selectable Turbo mode engaged. It keeps a 1/2-inch all-metal ratcheting chuck with carbide teeth, anti-kickback protection, a 22-position clutch, and a pre-light/after-glow LED in a 6.96-inch body. Pro Tool Reviews scored it 9.8/10, measuring it 23-26% faster than the outgoing model - top of their speed charts and second only to Makita's GPH03 in torque. Sold kit-first in the US at $299 with two batteries; the price shown is the kit.
Flex's full-size flagship pairs a sensor-free 24V brushless motor with a long 1-1/4 in stroke at 3,000 SPM and selectable orbital action. Pro Tool Reviews scored it 9.2/10 and found it out-cut most of the cordless field, and Bob Vila named it the top pick of seven saws tested — with vibration damping that reviewers consistently single out as best-in-class.
Flex's flagship 24V grinder, part of the brand's 2021 North American relaunch. A sensor-free brushless motor spins 4-1/2 or 5-inch wheels at up to 10,000 RPM - the highest top speed in this roundup - with touch-control speed settings of 3,500/5,000/7,000/10,000 RPM. Anti-kickback sensing stops the motor on bind-up, guard adjustment is one-step tool-free, and the vibration-suppression side handle tames buzz. FX3171A is the no-lock paddle version; FX3181A is the side-switch sibling. THERMA-TECH heat management and 24V packs push it toward corded-class sustained output.
