Kreg Tool Trim Router Base Plate with Handle for Circle Cutting, Fits Most Trim Routers (KRTBP100)
Key Features
Overview
The Kreg KRTBP100 Trim Router Base Plate is an oversized router accessory built to improve control, stability, and accuracy when using a compact trim router. This is a trim router base plate designed for smoother edge routing, circle cutting, and detail work in woodworking projects. Model Number: KRTBP100. If your trim router feels a little twitchy on narrow stock or near an edge, this accessory fixes that by giving the tool a larger, more stable footprint.
The big benefit here is simple: more base contact means more control. Instead of balancing a small trim router on a compact factory base, you get a larger clear platform that rides more confidently on the work surface. That matters when you are following an edge, trimming laminate, breaking corners, or making shallow pattern-routing passes where even a little tip can show up in the finished cut.
Kreg also built in an integrated handle, which is a practical upgrade for anyone who has spent time guiding a trim router one-handed. The extra grip point helps keep the tool planted and gives you a more natural way to steer it through longer cuts. On repetitive routing jobs, that translates to less hand fatigue and better consistency from pass to pass.
The clear base is not just for looks. Being able to see more of the work surface helps with alignment and makes it easier to track layout lines, edges, and cut paths. That is especially useful in detailed woodworking, cabinetry, sign work, and other jobs where placement matters as much as finish quality.
One of the more useful features on the Kreg KRTBP100 Trim Router Base Plate is its circle-cutting capability. Integrated pin holes allow you to cut circles from 3-1/2 in. to 15 in. diameter, which gives a trim router a lot more versatility in the shop. For small round parts, speaker openings, decorative details, and other repeatable circular cuts, this is a cleaner setup than improvising with a shop-made jig every time.
Compatibility is another strong point. Kreg states that this base plate fits most major trim routers, including the Kreg 20V Ionic Drive 1/4 in. Trim Router. That makes it a useful upgrade for woodworkers who already own a trim router and want better control without stepping up to a larger fixed-base router for everyday work.
In practical terms, this accessory makes the most sense for woodworkers, cabinet installers, furniture builders, and serious DIY users who do detailed routing and want a steadier feel from a compact router. If your work includes edge profiling, template routing, light groove work, or circle cutting, this base plate adds real utility without complicating the setup.

Pro Tip
When you are cutting circles, make a light scoring pass first before going to full depth. The KRTBP100 stays more stable than a small factory base, and that first shallow pass helps the router track cleanly on the final cut.
