Festool Domino Joiner DF 500 RQ Set with 1066-Piece Tenon Assortment (Updated 2026 Model)

The Festool Domino Joiner DF 500 RQ Set w/ 1066-Piece Tenon Assortment (Updated 2026 Model) is a complete loose-tenon joinery kit for furniture makers, cabinet builders, and trim carpenters. This is a joiner designed for cutting elongated mortises that accept Domino tenons, plus the tenons and cutters to use it across a full range of stock thicknesses. Model Number 578544-576794 combines the 578544 DF 500 RQ Set with the 576794 tenon assortment Systainer3.

The Domino cutter spins and swings side to side at the same time. That pendulum action cuts a clean, slightly oval mortise in seconds, and the flat Domino tenon that drops into it can't rotate. You get the strength of a traditional mortise-and-tenon joint with the speed of a biscuit joiner, and parts stay aligned during glue-up instead of twisting under clamp pressure. The DF 500 is the Festool Domino joiner sized for everyday furniture and cabinet work, while the larger DF 700 XL handles heavier frames and doors.

The 2026 RQ update is all about the fence. Four built-in indexing pins let you register the joiner against the edge of a workpiece or drop a pin into a mortise you already cut, then cut the next one at an exact, repeatable spacing. On a run of face frames or drawer boxes, that means fewer layout marks, fewer test cuts, and opposing mortises that actually line up.

The adjustments cover the jobs you actually do. The fence pivots from 0 to 90 degrees with positive stops at 22.5, 45, and 67.5 degrees for miters. Routing height adjusts from 3/16" to 1-3/16" (5 to 30 mm), and the depth stop has presets at 1/2", 9/16", 13/16", 1", and 1-1/8" (12, 15, 20, 25, and 28 mm). Mortise width adjusts with the turn of a dial, which gives you a little play side to side when aligning panels for glue-up. The joiner handles stock as thin as 1/2" (12 mm), so drawer parts and narrow frames are no problem.

The bundled Domino DF 500 1,060-piece tenon assortment is what makes this the set to buy. You get solid beech tenons in 4 x 20 mm, 5 x 30 mm, 6 x 40 mm, 8 x 40 mm, 8 x 50 mm, and 10 x 50 mm, plus the 4, 5, 6, 8, and 10 mm cutters to match. The tenons are embossed to spread glue and run about 1/16" (2 mm) shorter than nominal, leaving room for glue in the mortise so the joint doesn't push apart as you clamp it.

The motor draws 420 W and spins at 25,500 RPM no-load, tuned for controlled, precise cutting in solid wood and sheet goods rather than raw force. At 7.72 lbs it's light enough to carry to the jobsite or work on parts clamped flat on the bench. The 13.1 ft (4 m) plug-it cord detaches for storage and swaps with other Festool corded tools.

Dust control matters more on a joiner than most people expect. Chips packed into a mortise make the tenon fit tight in the wrong places, and debris over your pencil lines costs you accuracy. Hooked to one of the Festool dust extractors, the DF 500 RQ keeps the cut clear and the bench clean while you batch parts.

Who should buy it? Furniture builders, cabinet shops, finish carpenters, and serious woodworkers who want strong, repeatable joints without dragging parts to a stationary mortiser. If you are buying your first Domino, this bundle is the easiest way in: the machine, every common tenon size, and every matching cutter, organized and ready to go.

The Festool Domino Joiner DF 500 RQ Set w/ 1066-Piece Tenon Assortment Is the Right Way to Start

Buy the joiner alone and you'll be ordering tenons and cutters within a week. This bundle gets you every common size on day one.

• Who it's for: Furniture and cabinet builders, trim carpenters, and woodworkers buying their first Domino or replacing an older DF 500.
• Why it stands out: The 2026 indexing-pin fence speeds up layout, and the assortment covers 4 mm through 10 mm tenons with matching cutters.
• Worth knowing: The DF 500 tops out at 10 x 50 mm tenons. If you build doors, beds, or timber-scale frames, look at the DF 700 XL instead.

• What changed on the 2026 DF 500 RQ? The fence was updated with four built-in indexing pins for spacing mortises off a reference edge or an existing mortise without measuring.
• Do DF 500 tenons fit the DF 700? No. The DF 500 and DF 700 XL use different cutters and tenon sizes.
• How thin can the stock be? The DF 500 RQ joins stock as thin as 1/2" (12 mm) using the 4 mm cutter and tenons.
