Festool MFT Bench Dog 20mm Hole Plugs

MFT Table Hole Plugs

I created a 4x8 MFT style workbench and added holes using the Parf Guide system at 96mm intervals in a grid.

While the table has been awesome, at times I don't want things to fall through the holes and would prefer a solid, flat, hole-free surface. I designed these plugs to drop into the chamfered 20mm holes providing a flush plug when needed. Each plug has a 6mm nut threaded onto the bottom which, combined with a magnet, allows the plugs to be easily removed when necessary. 

The holes can be chamfered using this tool which you attach to a drill. It makes a nice chamfer around the edge of the hole while it cleans out any glue and other materials that may have accumulated. It's a must-have tool for any MFT style bench  in my opinion.

Here's one that you can turn by hand.

There are knock-off version of this on Amazon but I haven't tested them so they may be a different size chamfer. I have on on order and will update this post if it turns out to be a good alternative.

There's a magnet embedded in a knurled holder to pull the plug from the hole. They use 12x3mm magnets which can be purchased here: https://amzn.to/4a2DaTc

Each plug has a steel nut screwed to the plastic threads inside the plug. I found some cheap nuts on Amazon.

Note many of the nuts shown on the site are Stainless Steel and they are not magnetic.
