Category: Flush Trim Router Bits

Overview

This premium Whiteside pattern bit is built for premium template routing with larger handheld routers and router tables. Its compression-style cutting geometry helps produce clean top and bottom edges, making it a strong choice for pattern work, mortises, dados, rabbets, and other guided cuts where finish quality matters.

The top bearing follows your template or reference edge during router use, and the removable bearing gives you more setup flexibility where appropriate. Use this bit with stable workholding, a well-supported template, and multiple passes when cutting deeper profiles.

This is a heavier-duty 1/2″ shank pattern bit for larger routers and controlled setups. For smaller trim-router work, choose a 1/4″ shank pattern or flush trim bit instead.

Ruby N. ★★★★★

Picked this up for template routing on some hard maple, and the AstraHP coating really does help the bit glide through without gumming up. The 1-1/8″ cut depth handled my 3/4″ templates with zero tear-out on the top or bottom edges.

Natalie F. ★★★★★

Cut through a full 2x4 in a single pass with my router table, and the AstraHP coating still looks like new after a dozen uses — zero burn marks on the edge.

Samuel ★★★★★

Fired up the router table for some template work yesterday and this bit chewed through a full sheet of 3/4" ply without a hint of burning, that compression geometry really does keep both edges clean. The 1-1/8" cut depth meant I could run the whole pass in one go instead of stacking cuts, which save
