Trim Router Circle Guide Kreg KRTCG100 For Precise Cuts

Trim Router Circle Guide Kreg KRTCG100 is a circle-cutting guide from Kreg Tool designed for trim routers, so it turns a standard handheld trim router into a controlled circle-cutting setup for woodworking projects. The guide is built to easily create clean, precise circles from 3-1/2-in to 52-in diameter, which lets you handle everything from small cutouts to large panels with the same tool setup. Pin holes on the guide allow both interior and exterior diameter cutting, so you can cut round blanks or circular openings while keeping the cut centered. The guide also provides extra stability and control for edge profiles when you are not cutting circles, helping the router track more consistently along workpiece edges. An integrated handle ensures a secure grip and reduces fatigue during extended use, which supports steadier control across longer routing passes.

Key Circle Cutting Details Woodworkers Rely On

• The ability to create circles from 3-1/2-in to 52-in diameter lets one setup cover small to large projects, so jigs for multiple sizes are not required and layout time on site or in the shop stays consistent.
• Pin holes that support both interior and exterior diameter cutting allow the same guide to cut circular openings or solid disks, which helps keep center alignment predictable for matching parts like lids and inserts.
• Extra stability and control for edge profiles mean the guide supports the router base as it follows edges, so profile bits track more smoothly and reduce the chance of wobble along visible edges.
• The integrated handle that ensures a secure grip and reduces fatigue during extended use gives hands a fixed reference point, which helps maintain steady feed pressure and smoother finishes on longer passes.
• The clear base made for improved visibility and control lets you see the bit and cut line as you move, which helps keep the cut on layout marks when working to tight dimensions.
• The construction from impact-resistant polymer gives the guide a durable body, so it stands up to normal jobsite or shop handling while keeping reference surfaces stable over repeated use.

Circle Guide Setup, Stability, And Router Fit

The trim router circle guide is compatible with most major trim routers, including Kreg's Ionic Drive 1/4-in Trim Router, so it supports common trim router platforms in cabinet and woodworking shops. This compatibility lets installers and woodworkers move between different trim routers while keeping the same circle cutting process, which simplifies workflow on mixed-tool jobs. The guide's clear base improves visibility and control around the bit, so alignment to layout lines during setup is more straightforward. The integrated handle gives an additional contact point during routing, which helps stabilize the router when starting cuts on a layout mark or when following a circle path.

Using The Trim Router Circle Guide In Woodworking

Where This Trim Router Circle Guide Works Best

This trim router circle guide from Kreg Tool is designed for routing tasks where controlled circular cuts or guided edge work are required in woodworking. The ability to easily create circles from 3-1/2-in to 52-in diameter supports jobs ranging from small access holes to larger table or panel cutouts, so one guide can cover a broad range of shop and installation work. Pin holes that allow both interior and exterior diameter cutting mean it can be used to cut circular openings in panels or to cut round blanks, making it useful for projects like speaker openings, round shelves, or decorative panels. The extra stability and control it provides for edge profiles helps when running bearing-guided or non-bearing bits along workpiece edges, so edge treatments stay consistent around visible parts. The clear base and integrated handle work together to support accurate tracing of layout lines because the operator can see the bit and hold the tool with consistent pressure as the cut follows the marked circle.

Why These Router Circle Guide Details Matter

The wide circle range from 3-1/2-in to 52-in diameter matters because it lets a single trim router circle guide handle repeated layouts across small and large parts, which helps keep jig changes off the critical path of a job. Impact-resistant polymer construction keeps the guide body stable under typical shop use, so reference points for circle radius do not shift over time and repeat cuts stay consistent. The clear base that is designed for improved visibility and control matters when working to existing layout lines or when matching parts, since you can track the bit against the mark throughout the cut for more accurate results. Pin holes for both interior and exterior diameter cutting give flexibility in how material is removed, which supports cutting either the inner waste or the outer waste depending on project needs. The integrated handle that ensures a secure grip and reduces fatigue during extended use helps keep hand positions steady around a full circle, supporting smoother cuts that require less sanding afterward.
