DF 500 vs DF 700: Core Differences At a Glance
Festool only offers two Domino joiners in 2026, and they are not interchangeable. They use different cutters, different Domino tenons, and cover different stock thicknesses. Choosing by the thickness you build with most often prevents buying the wrong consumable system.
| Specification | Festool Domino DF 500 Q | Festool Domino XL DF 700 Q |
|---|---|---|
| Mortise Width (cutter diameter) | 4mm, 5mm, 6mm, 8mm, 10mm | 8mm, 10mm, 12mm, 14mm |
| Max Mortise Depth | 28mm | 70mm |
| Depth Adjustment Steps | 12mm, 15mm, 20mm, 25mm, 28mm | 15mm to 70mm, continuously variable with depth stop |
| Domino Tenon Range | 4x20mm to 10x50mm | 8x40mm to 14x140mm (14×140 requires double mortise technique) |
| Stock Thickness Range (recommended) | 12mm to 28mm | 25mm to 70mm+ |
| Mitre / Bevel Fence Range | 0-90 degrees with positive stops at 22.5, 45, 67.5 degrees | 0-90 degrees with positive stops, wider fence body |
| Cutter Speed | 25,500 RPM | 21,000 RPM |
| Weight (without systainer/accessories) | 3.2 kg (7.1 lbs) | 5.2 kg (11.5 lbs) |
| Dust Extraction Port | 27mm | 36mm / 27mm with adapter |
| Power | 420W, corded | 720W, corded |
The key takeaway is not power or weight, it is tenon scale. The DF 500 cuts the mortise sizes used for 3/4-inch cabinet plywood, face frames, rail-and-stile doors, and solid-wood furniture up to about 1-1/8 inch thick. The DF 700 cuts the mortise sizes used for workbench legs, thick slab tables, exterior doors, and timber framing details where a 6mm or 8mm tenon would be undersized.
How Mortise Capacity Affects Real Projects
Furniture and Cabinets: Where the DF 500 Excels
For stock between 12mm and 28mm, the DF 500 gives you five tenon diameters and a tighter mortise pitch. The 4mm and 5mm cutters are essential for drawer boxes, small boxes, and 1/2-inch plywood partitions where an 8mm cutter would blow out the side. The fence registers accurately on narrow stock down to about 36mm wide, and the retractable pins and clear sight window make alignment on 18mm Baltic birch or 19mm hardwood repeatable without marking every centerline.
You also get the full Domino width adjustment. The machine cuts a standard width mortise or a wider mortise (about 6mm wider than the tenon) to allow lateral float for panel glue-ups. This is how you keep a tabletop flat while accounting for small layout errors, and it is why the DF 500 is faster than a biscuit joiner for edge-to-edge glue-ups in 20mm to 28mm tops.
Large-Scale and Thick Stock: Where the DF 700 Is Required
Once stock passes 28mm, the DF 500 cannot center a tenon properly or provide enough glue surface. The DF 700 adds 12mm and 14mm cutters with depths to 70mm, which lets you place two or three 14x140mm tenons in a single 60mm thick leg-to-apron joint. The larger fence and heavier base plate reduce tipping when you plunge vertically into 40mm+ end grain, which is common for bed frames and entry doors.
The DF 700 can still cut 8mm and 10mm mortises, so it technically overlaps the top end of the DF 500. In practice, the added weight and larger fence make it cumbersome for frequent 12mm to 19mm work. If most of your work is under 28mm, the overlap does not justify using the larger machine daily.
Alignment Features That Change Accuracy and Speed
Both machines share the core Domino system: height-adjustable fence with scale, flip-down support feet, retractable cross-stop pins, and indexing against a previous mortise. The differences that matter for purchase decisions are:
- Fence stability on narrow stock: The DF 500 fence kit includes a narrow-stock adapter and trim stop. The DF 700 relies on its wider fence and optional XL trim and cross stops for similar work, but balancing the 5.2 kg body on 40mm trim requires two hands and a clamped workpiece.
- Sight window and pin spacing: Both use the same pin logic for rapid repeat mortises without measuring. The DF 500 pins index perfectly for 4mm to 10mm tenons at 37mm spacing. The DF 700 pins are spaced wider to match larger tenon separation for structural joints.
- Depth logic: The DF 500 uses preset depth stops, which is faster for cabinet batch work where you alternate between 15mm and 25mm depths. The DF 700 uses a variable depth stop with scale, which you need when tuning depth for 50mm, 60mm, or 70mm tenons in thick stock.
- Dust extraction dependency: Both require extraction to clear the mortise. Without it, chips pack in the cut and you get shallow or scorched mortises. If you work without a CT extractor, use a 36mm hose with a 27mm adapter and clean the mortise with a second plunge.
Consumable Cost: Tenons, Cutters, and Cost Per Joint
The Domino system locks you into proprietary beech or sipo Domino tenons and dedicated cutters. Generic dowels do not work. Beech is standard for interior furniture, sipo (mahogany-like) is for exterior or high-moisture exposure. Cutters are solid carbide spiral bits specific to each machine and diameter.
Market ranges in 2026 are fairly stable: Domino tenon assortments run about $90 to $180 for 500-1000 pieces depending on size, and individual cutter prices run $35 to $65 for DF 500 sizes and $55 to $90 for DF 700 XL sizes. Sipo tenons cost roughly 30 to 40 percent more than beech.
| Joint Example | Machine and Tenon | Typical Retail Cost Per Tenon (Beech) | Cost Per Joint (2 tenons + cutter wear) |
|---|---|---|---|
| Cabinet face frame, 19mm hardwood | DF 500, 5x30mm | $0.09 – $0.13 | $0.22 – $0.32 |
| Plywood carcass, 18mm | DF 500, 6x40mm | $0.11 – $0.15 | $0.26 – $0.38 |
| Solid wood table apron to leg, 40mm | DF 700, 10x50mm or 12x100mm | $0.18 – $0.28 (10mm), $0.45 – $0.65 (12mm) | $0.42 – $0.62 (10mm), $0.98 – $1.38 (12mm) |
| Exterior door rail, 45mm sipo | DF 700, 14x100mm sipo | $0.70 – $0.95 | $1.50 – $2.05 |
Worked calculation for a common shop scenario: A base cabinet with 4 face-frame joints, 8 carcass joints, and a 5-board top glue-up with 8 tenons uses 20 tenons total. With DF 500 5x30mm and 6x40mm beech tenons, consumable cost is about $2.20 to $3.10 per cabinet plus negligible cutter wear if extraction is used. A dining table with 4 legs, 8 apron joints using two 12x100mm tenons per joint (16 tenons) costs about $7.20 to $10.40 in tenons alone. Over a year at two tables per month, the DF 700 tenon cost is $175 to $250, which is why shops that build thick furniture buy tenons in bulk boxes of 750 to 1000 and reserve sipo only for exterior work.
Cutter life is the hidden consumable. With dust extraction and clean wood, a DF 500 carbide cutter lasts 800 to 1200 plunges in hardwood before the mortise starts to tighten or burn. In MDF, particleboard, or reclaimed wood with grit, life drops to 400 to 600 plunges. A dull cutter causes undersized mortises that require hammering the tenon and risk splitting the stock. Replace cutters when you feel increased resistance or see darkening in the mortise walls.
Decision Matrix: Which Setup Fits Your Situation
| Your Situation | Recommended Setup | Why |
|---|---|---|
| Small shop, 60-90 sq ft, mostly cabinets, bookcases, and trim under 28mm | DF 500 with 5mm, 6mm, 8mm cutters | Covers 90 percent of interior work, lighter to handle, lower consumable cost |
| Furniture maker building tables, beds, workbenches with 30mm to 60mm stock | DF 700 with 10mm, 12mm cutters | Needed tenon cross-section and depth for structural joints |
| Mixed shop doing both cabinets and occasional thick slabs | DF 500 as primary, add DF 700 later or rent/borrow for thick builds | Avoids daily handling of heavy machine for light stock; DF 500 tenons are cheaper for high-volume cabinet work |
| Trim and door installer, interior doors and jambs | DF 500 with trim stop and cross stop | Fast alignment on site, works with 18mm to 25mm casings and sills |
| Exterior door, gate, and pergola builder | DF 700 with sipo tenons and 12mm/14mm cutters | Weather-resistant tenons and deep mortises for 40mm+ stock |
| Tight budget, one machine only, stock rarely exceeds 30mm | DF 500 | General market range is lower for machine, cutters, and tenons; more versatile for thin stock |
Durability and Ownership Realities
Both machines are corded and built for site use, but they are not designed for open dust environments. What wears first is predictable.
- Fence slop: The height adjustment rack collects fine dust. If the fence drifts 0.2mm, tenons will not sit flush. Vacuum the rack after each session and wax the fence columns lightly. Check fence lock tension monthly.
- Plunge mechanism: Grit in the plunge rails causes a sticky return stroke. Blow out with filtered air and avoid silicone lubricants that attract dust. A slow return is a sign to clean, not to add oil.
- Cutter collet: The 8mm collet on the DF 500 and 12mm on the DF 700 must be cleaned with a brass brush. Resin buildup leads to runout and oval mortises. Replace collets if a cutter shows visible wobble.
- Common mistakes: Plunging too fast in hard maple burns the cutter and glazes the mortise, weakening glue bond. Plunging without extraction in MDF packs the mortise floor, resulting in a tenon that bottoms out 2mm short and leaves a gap. Always make a second light plunge to clear the cut.
- Storage: Domino tenons swell with humidity. Beech tenons stored open in a damp shop can expand 0.1mm to 0.2mm and will not fit a fresh mortise. Keep them in the systainer with the lid closed and add a small desiccant pack if your shop is not climate controlled.
Both tools use the same service logic as other Festool corded tools: carbon brushes are replaceable, and the motor housings are sealed against fine dust but not waterproof. If you cut a lot of MDF or HDF, clean the motor vents weekly to prevent heat buildup.
Which Accessories Actually Matter
For the DF 500, the cross stop and trim stop are the two accessories that change speed the most for cabinet work, because they let you register off the end of a rail without measuring. The 4mm cutter is worth owning only if you build drawers or small boxes regularly. For the DF 700, the support bracket and XL trim stop are more important than extra cutters, since the machine’s weight makes unsupported plunges inaccurate.
If you own both machines, do not try to adapt cutters between them. The shank diameter and rotation speed are different, and the mortise geometry will be incorrect.
FAQ
Can the DF 700 replace the DF 500 if I buy one machine?
Only if you rarely work under 25mm. The DF 700 can cut 8mm and 10mm mortises, but its weight, fence size, and minimum tenon size make it impractical for 12mm to 19mm drawers, thin face frames, and small boxes. Most shops that try to use only the DF 700 end up adding the DF 500 later.
Do I need sipo tenons for interior furniture?
No. Beech is stronger in interior conditions and costs less. Use sipo only for exterior, high-humidity, or treated-wood applications where beech would swell or decay.
Are Domino joints as strong as traditional mortise and tenon?
For furniture and cabinets, a double Domino joint with modern PVA or polyurethane glue tests comparably to a traditional mortise and tenon in the same stock thickness, because the glued face-grain surface area is similar. For large structural joints over 45mm thick, traditional long tenons or multiple 14mm Dominos with epoxy provide higher resistance to racking, which is why the DF 700 allows depths to 70mm.
