Category: Pattern Router Bit Template Bits

Overview

This 1/2″ down-cut pattern bit is built for template-on-top routing with handheld trim routers and compact routers. The top bearing follows your template while the down-cut geometry helps press fibers down for a cleaner top edge.

Use this bit for pattern work, edge cleanup, shallow recesses, and controlled trimming after removing most of the waste. Keep the bearing fully supported by a clean, stable template edge and avoid forcing wide, full-width cuts.

For larger routers, router-table use, heavier trimming, or repeated production work, step up to a 1/2″ shank tool where appropriate.

The 3/4″ cutting length is useful when you need more depth than a shallow mortising bit but still want a compact, controlled pattern bit.

Carter F. ★★★★★

The down-cut design kept my trim router from lifting the veneer—huge relief. Cuts smooth and the coated bit shows no wear after several template runs.

Michael P. ★★★★★

Finally, a pattern bit that actually pulls the chips down instead of blowing them everywhere—the down-cut geometry makes a huge difference on my template jobs. The AstraHP coating seems to be holding up well after several uses, and the 1/2-inch shank keeps things nice and stable in my trim router.

John ★★★★★

The down-cut spiral really keeps the top edge clean—no fuzz or tear-out on the plywood template I ran it over. The bearing rides smoothly against the pattern, and the 3/4″ cutting depth handled my stack without bogging down the trim router.
