Flex 24V Compact Router Review: A Surprisingly Well-Built Cordless Trim Router

Introduction

The Flex 24V compact router is one of the newest routers on the market, and it arrives with a few features that genuinely haven’t appeared on other routers before. It’s a cordless, 24V, compact-format tool that only accepts quarter-inch shank bits, so it’s aimed at edge work, round-overs, trim, and small detail routing rather than heavy table-mounted work.

If you follow cordless tools, you may notice the general shape resembles other compact routers from brands like DeWalt, Milwaukee, or Makita. That’s fair, but it’s also true of the whole category: impact wrenches look like other impact wrenches, drivers look like other drivers. What matters is what this one does differently, and Flex has packed in a few things worth knowing about.

Who This Product Is For

This is a router for woodworkers, trim carpenters, and DIY builders who want a powerful cordless option for edge profiling, hinge mortising, small dadoes, and general trim routing. Because it only accepts quarter-inch shank bits, it’s not the right pick if your workflow depends on half-inch shank bits.

It’s also a good fit for anyone already invested in Flex’s 24V battery platform. The router runs on the larger 5Ah stacked-lithium pack, which adds a bit of size, but smaller packs like the 3.5Ah make the whole setup more compact if you prefer to trade runtime for a smaller footprint.

Build Quality and In the Box

Right out of the box, this thing is beefy in the best sense. The rubber over-mold grip cups into your hand comfortably, and the overall construction feels extremely solid, which is consistent with how Flex tools are generally built. Once you lock the depth adjustment in, the router doesn’t move; the whole assembly feels planted.

The top of the motor barrel houses a variable speed dial for adjusting RPM, and instead of a traditional trigger-style switch, Flex uses a large digital power button positioned around the grip. It’s big enough that you can hit it without repositioning your hand mid-work, which is a small touch that makes a real difference during longer sessions.

The Included Accessories

Flex includes a genuinely useful kit here. You get an adjustable fence that Flex describes as heavy duty and legitimately easy to adjust, two different wrenches for bit changes, a dust collection shroud, and two different base plates: one conventional squared-off plate and one larger, rounder plate.

The dual base plates matter more than they might seem. Many more expensive brands ship compact routers with a very small base plate, which makes edge work feel precarious and can mar your workpiece. Having two sturdy plates included solves that.

The fence attachment system is the best of its kind here: there’s a small locking button and a notch on the underside of the fence. You drop it into place, flip a lever, and it locks solidly. Adjusting the offset takes seconds: pop it in, raise or lower it about an eighth or a quarter of an inch, tighten down, and it stays put.

A First We Haven’t Seen Before: The Centering Collar

The strangest and most interesting accessory is a small tapered collar. It took some figuring out, but its purpose is clever: you place it over the bit, tighten it, and it centers the bit perfectly in the base opening. When you swap base plates, the bit lines up automatically without any fuss.

No other router reviewed here has included anything like this. If you’ve ever fought with a bit that sits slightly off-center after a base swap, this feature alone is worth a look.

There’s also a dedicated lock and unlock switch for bit changes. On most compact routers you have to hold a spindle button down while wrestling the collet nut with a second hand. Here you just flip to lock, change the bit with both hands free, and unlock when you’re ready. Note again: quarter-inch shank bits only, no half-inch.

Performance in Use

Power is there. Testing with a genuine Diablo quarter-inch round-over bit, the router cut cleanly and confidently, and the speed dial gives you plenty of headroom if you want to push faster.

Vibration is minimal. Even running a larger 5Ah battery, the tool stays smooth and comfortable in hand, and the balance works with the grip rather than against it.

Dust collection performed well with a shop vacuum hooked into the shroud. Flex makes its own vacuum, but any brand’s vacuum should work with the port. During edge profiling, nearly all the dust was pulled away, with only a faint trace left behind that a quick reposition of the fence picked right back up.

Things to Consider Before Buying

A few practical points before you commit:

• It’s a compact router, so it accepts quarter-inch shank bits only. If half-inch bits dominate your collection, plan accordingly.
• With the 5Ah stacked-lithium battery attached, it’s noticeably heavier and bulkier. The smaller 3.5Ah pack trims that down if you want a more compact setup.
• Like any new platform tool, it makes most sense if you’re already in, or willing to join, the Flex 24V battery ecosystem.

What Stands Out

The centering collar is the headline feature: nothing else in the compact router class offers automatic bit centering across base plates. The lock/unlock switch for bit changes is the second standout, eliminating the awkward two-handed fumbling most routers demand. Add in the dual heavy-duty base plates, the excellent quick-lock fence, strong dust collection, low vibration, and genuinely premium build quality, and this router earns its professional-grade billing.

Buying Advice

If you’re shopping for a compact cordless router, this deserves a spot on your shortlist, especially if you already own Flex 24V batteries. The feature set punches above what the established brands include at this format, and the build quality holds up under real use. If you need half-inch shank capability or a full-size router for heavy stock removal, look elsewhere; this is a trim and detail specialist.

Conclusion

The Flex 24V Compact Router is powerful, extremely well built, and thoughtful in ways its competitors aren’t. The bit-centering collar and lock/unlock switch alone make it easier to live with than most compact routers, and the included accessories are better than what pricier brands typically supply. For edge work and trim routing on the Flex platform, it’s a strong recommendation.
