Lightweight, precise and thoughtfully engineered, with enough power to handle real-world woodworking tasks without feeling like a compromise compared to a corded model.
A good 1/4″ cordless trim router can be one of the most versatile tools in your shop. It’s my tool of choice for rounding over edges, cutting hinge mortises, trimming veneer, or doing light joinery. When selecting a trim router there are a few key things that you’ll want to pay attention to.
First and foremost is power and speed. Even though these compact routers are smaller than their full-size cousins, they should have enough torque to cut cleanly through hardwoods without bogging down. Look for variable speed control so you can match the bit speed to the material — slower for dense woods and faster for softwoods or laminate trimming.
Ergonomics also matter more than most people realize. A well-balanced router with a comfortable grip lets you guide the tool confidently along edges or templates. You want a router that has a smooth, precise depth adjustment and a clear sightline to the bit, so you can see exactly what’s happening as you work.
Runtime is another consideration. Modern lithium-ion batteries have made cordless routers a pleasure to use, but battery life still varies. Ideally, the router should have a brushless motor for better efficiency and longer life. Dust collection and baseplate visibility are also features that make a big difference in day-to-day use, especially if you work indoors or on finished surfaces.

I’ve recently been using the new Kreg 20V Ionic Drive Trim Router, and it’s a solid example of how far cordless technology has come. The router is powered by Kreg’s 20V Ionic Drive system, which consists of their 20-volt “Blue Ion” lithium batteries (nominally 18V), brushless motor, LED work lights, tool-less adjustments and ergonomic design. In use I found it maintains speed nicely when routing hardwood edges — a good sign that the motor and electronics are well-tuned.
I like that the lock and power buttons are sealed — it helps protect internal components from fine dust, extending the tool’s lifespan. The lock button also controls the LED light.
The 6 speed settings from 10,000 to 30,000 RPM offers plenty of flexibility to handle a wide variety of bits, materials and routing tasks. The low end is ideal when using larger diameter bits and routing harder woods. I keep the dial in the middle when I’m using small- to medium-size bits, when edge profiling and when trimming solid wood. I use the high speeds for small bits and light cuts, such as when trimming veneers or laminate edges.
The router comes with both 1/4″ and 6mm collets. All my small diameter bits have either 1/4″ or 8mm shanks. 6mm (around 7/32″) does seem an odd choice to include as an extra collet. To my knowledge, none of the major bit manufacturers make 6mm shanked bits.
The micro-adjustment dial and rack-and-pinion adjustment is a key feature that works well, enabling me to have precise and smooth control over bit depth — this is especially useful when I’m fine-tuning cuts such for dadoes, grooves or edge profiles.
As I’ve found on just about all small routers, the depth scale is difficult to read except in perfect lighting.
The scale is in 1mm (1/16″) increments. I typically set the routing depth using a set-up block, and if a fine adjustment is needed, use the micro-adjustment dial.
Removing the clear subbase is quick and easy — you need to do this to install the template guide. The guide only accepts bits up to 5/16″ diameter. Unfortunately the subbase doesn’t accept universal template guides.
The clear base and bright LED light make it easy to see your workpiece, which helps when following layout lines or working on detailed edges.
Comfort is another strength. The router’s compact form and soft-grip body make it comfortable to use one-handed, and the balance feels right whether you’re trimming a laminate edge or rounding over a tabletop.
Kreg also includes a dust port that connects to a small extractor — something that’s not always standard on trim routers but makes a noticeable difference in visibility and cleanup. The dust port, as on other Kreg power tools, is 1-1/4″ diameter. Unfortunately it doesn’t connect directly onto my Festool or Bosch hoses, so an adapter is necessary. But once connected, dust control overall is excellent and helps maintain visibility while routing.
Overall, the Kreg 20V Ionic Drive Trim Router feels like it was designed by people who actually use routers. It’s lightweight, precise and thoughtfully engineered, with enough power to handle real-world woodworking tasks without feeling like a compromise compared to a corded model.
