Category: Flush Trim Router Bits

Overview

This 1/4″ up-cut spiral flush trim bit is built for clean, precise edge trimming with handheld trim routers and compact routers. The bottom bearing follows your template or reference edge while the up-cut spiral helps clear chips during controlled trimming passes.

Use this bit for template work, edge cleanup, and light flush trimming after rough-cutting close to the line. For heavier trimming, router-table use, or repeated production work, step up to a 1/2″ shank flush trim bit.

Customer Reviews (5.0 / 5 · 5 reviews)

Aurora ★★★★★

The up-cut spiral design shears through plywood like butter, leaving a glass-smooth edge on my template work. I used it on a curved laminate countertop and the bearing followed perfectly with zero burning or chatter.

Timothy V. ★★★★★

Bottom bearing tracked the template perfectly, no grab or chatter even on a curved edge. The up-cut spiral left a smooth finish that needed almost no sanding afterward.

Chloe ★★★★★

The up-cut spiral cleared chips so fast that I didn’t have to stop mid-pass on a long oak edge, and the bearing stayed true the whole cut. It’s a bit pricier than basic bits, but the finish left zero fuzz for a 5-star trim job.
