Perfect for cordless trim routers and router tables, our 1/4″ Compression Flush Trim Router Bit is built to tackle tight curves and intricate profiles with ease.

Category: Flush Trim Router Bits

Overview

This 1/4″ compression spiral flush trim bit is built for clean, controlled trimming with handheld trim routers and compact routers. The compression geometry helps produce crisp top and bottom edges, while the top and bottom bearings give you flexibility to follow a template or reference edge from either side of the workpiece.

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

Customer Reviews (4.4 / 5 · 5 reviews)

Lily ★★★★★

Used this bit today to flush-trim some walnut veneer and it left a glass-smooth edge with no tear-out on either the top or bottom. The spiral cut cleared chips quickly even with my small trim router.

Charlotte X. ★★★★★

The compression geometry really does its job—the top and bottom edges came out clean on both sides of my plywood without any tear-out. I ran it through a tight curve with my trim router and it tracked smoothly without wandering.

Alexander ★★★★☆

After using this bit on a few projects, the clean finish it leaves on both top and bottom edges is a noticeable upgrade. The AstraHP coating seems to help it slide through the wood without burning. Just wish the cut length was a tad longer for deeper passes.
