MFT 20mm Bench Dog Hole Router Jig

If you’re building or upgrading an MFT-style workbench, this jig makes it easy to route clean, accurate 20mm bench dog holes on a 96mm grid using a plunge router. It’s designed around the standard Festool-style layout, but works with any 20mm / 96mm hole pattern.

The template uses 1" guide holes paired with a 1" guide bushing and a 20mm router bit. Because the bit matches the final hole size, each hole can be cut with a single plunge. No spiraling out the cut. No extra cleanup passes. Just fast, clean, repeatable holes.

Recommended Bit

I’ve had good results with this 20mm bit:

These 7/8" OD bushings work well:

Instructions

1. Use double sided tape or clamps to position the jig.
2. The 1" guide bushing should fit snuggly into one of the 9 holes in the jig.
3. Cut as many of the 9 holes as possible depending on clamp placement
4. Use my 20mm bench dogs (my MFT 20mm Bench Dog Set – 96mm System) to index the jig. They’re designed for a snug fit in freshly routed holes, making it easy to reposition the template accurately as you move to the next section.
5. Cut the next set of holes.
6. Continue repositioning and routing until your full grid is complete.

If you're printing on a P1S, be sure to use the print profile specifically made for that printer. The original profile is slightly too large and encroaches into the physical exclusion zone.
