Key Features
Overview
The Festool 578121 Cordless 18V Domino Joiner DFC 500 E, Tool Only is the battery-powered version of Festool's DF 500 Domino, built for furniture makers, cabinet installers, and finish carpenters who want loose-tenon joinery anywhere on the job. This is a joiner designed for cutting elongated mortises that accept Domino tenons in solid wood and sheet goods. Model Number 578121 ships as a bare tool with a 5 mm cutter, support bracket, wrench, and Systainer3 case. Battery and charger are sold separately.
The Domino cutter spins and swings side to side at the same time. That pendulum motion cuts a clean, slightly elongated mortise in seconds, and the flat Domino tenon that goes into it can't rotate. You get the strength of a mortise-and-tenon joint with the speed of a biscuit joiner, and rails, stiles, and panels stay aligned at glue-up instead of twisting under clamp pressure. Among cordless joiners, it's the one that cuts true loose-tenon mortises, which is what you want when there's no outlet nearby or a cord keeps catching on the work.
The adjustments cover the work most shops actually do. Routing height adjusts from 3/16" to 1-3/16" (5 to 30 mm), the fence tilts from 0 to 90 degrees for miter joints, 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). The DFC 500 accepts the full range of DF 500 cutters in 4, 5, 6, 8, and 10 mm, so the same machine handles thin drawer parts and 1" face frames.
The motor spins the cutter at 18,500 RPM no-load, which is tuned for controlled, accurate plunges rather than brute speed. A spade-style D-handle gives you a firm grip for straight plunges, and the tool weighs 7.5 lbs (3.4 kg) without a battery. That's light enough to work on parts clamped flat on the bench or hold against the side of an installed cabinet.
The included 5 mm cutter gets you started, but most buyers add tenons and cutters right away. The Domino DF 500 1,060-piece tenon assortment covers six tenon sizes from 4 x 20 mm to 10 x 50 mm and includes all five matching cutters in one organized Systainer3.
Chips packed in a mortise make tenons bind in the wrong places, and dust over your layout marks costs accuracy. The 1-1/16" (27 mm) extraction port connects to a Festool hose, so the cut stays clear while you work through a stack of parts.
Power comes from the Festool 18V battery system. If you already run Festool cordless drills, sanders, or saws, your packs and chargers work here. If you're starting fresh, the Festool 18V 5.0Ah Battery 2-Pack and TCL 6 Charger Energy Set gives you two packs to rotate through a long day of joinery.
Who should buy it? Cabinet installers, trim carpenters, and furniture builders who join parts on site or move between bench, assembly table, and install location. If all your joinery happens at one bench next to an outlet, the corded DF 500 does the same cutting without the battery investment. If you're already on Festool 18V, the cordless model is the easy call.
Joinery That Goes to the Work
With no cord to manage, you can work around a large panel or a cabinet that's already installed without stopping to reposition a power cord or extension.
- 18V cordless operation
- 7.5 lbs (3.4 kg) tool weight without battery
Set the Depth Once
The depth stop presets match common Domino tenon lengths, so switching from 5 x 30 mm to 8 x 40 mm tenons is a quick turn instead of a test cut.
- Depth presets: 1/2", 9/16", 13/16", 1", 1-1/8" (12, 15, 20, 25, 28 mm)
- Routing height 3/16" to 1-3/16" (5 to 30 mm)
Clean Mortises, Visible Lines
Connected to one of the Festool dust extractors, the port pulls chips out of the mortise while the cutter works, so tenons seat fully and you aren't blowing out each slot before glue-up.
- 1-1/16" (27 mm) extraction port
- Keeps layout lines visible during the cut
Index Off What You Already Cut
The indexing pins let you register the joiner against the edge of a board or drop into the previous mortise, which keeps spacing consistent across a run of drawer boxes or face frames.
- Built-in indexing pins for repeat placement
- Fence angle 0 to 90 degrees

Pro Tip
Mark a reference face on every part and keep the fence on that face for every cut. Mating parts then come out flush even if your stock thickness varies a little from board to board.

Tool Nut's Take
The Festool 578121 Cordless 18V Domino Joiner DFC 500 E Takes the Domino to the Install
Same Domino joinery that made the DF 500 a shop staple, now without the cord, which matters most when the cabinet is already on the wall.
- Who it's for: Cabinet installers, trim carpenters, and furniture builders already on Festool 18V, or ready to buy in.
- Why it stands out: Cordless freedom with the same cutter range, depth presets, and indexing pins as the corded DF 500.
- Worth knowing: Bare tool with one 5 mm cutter and no tenons. Budget for batteries, a charger, and a tenon assortment, and step up to the Domino Joiner XL DF 700 EQ if you build doors, beds, or heavy frames.
Common Questions
- Does it come with a battery? No. This is tool only. It runs on Festool 18V batteries, sold separately along with a charger.
- Does it use the same tenons as the corded DF 500? Yes. It takes DF 500 cutters from 4 to 10 mm and the matching DF 500 Domino tenons.
- How deep can it cut? Maximum routing depth is 1-1/8" (28 mm), with presets at 12, 15, 20, 25, and 28 mm.
