The Festool DF500 is a machine for cutting mortices for loose tenon joints.

A loose tenon joint is similar to a mortice and tenon joint, except both work pieces have a mortice and a separate loose tenon joins the two pieces.

At Makespace we have a DF500 with 4, 5, 6, 8, and 10mm cutters.

Festool makes pre-cut tenons, referred to as Dominos, which are available for purchase from Makespace.

When to use a Domino Joiner

  • The DF500 is a machine for quickly and accurately cutting mortices for loose tenon joints.

  • You can use the Domino Joiner to create Rail to Post, End to End, Edge to Edge, Edge to Face and Mitre Joints.

  • Domino joints can be load bearing or structural joints, multiple Dominos can be cut for a single joint for extra strength.

  • Dominos can also be used for alignment, even in cases where a tenon is not really required for strength, such as a table top glue up.

How Good is a Domino Joint

  • Despite the name, Loose Tenon Joints are every bit a strong as a Mortice and Tenon.

  • As long as you have a good long grain to long grain surface bond, either between the joined components or between the Domino and the mortice, you should achieve a strong joint.

  • Mortice & Tenon joints and a Domino joints are both strongest in the axis perpendicular to the tenon.

  • Domino joints can be cut in places where a Mortice and Tenon would be impractical such as the corner of a cabinet formed from MDF or Ply.

  • Dominos are useful for alignment e.g. to locate the end of a leg to a table top.

  • Domino joints can be cut very quickly and accurately, with little marking up which makes them very efficient to use.

What other tools/equipment can be used instead?

Mortice and Tenon Joints can be cut with a chisel, saw and shoulder plane.

Decorative effects such as Dovetails can be cut by hand.

Mortices can be cut with a Router using a jig.
