Festool | DF 500 RQ-Plus DOMINO Joining Machine

The Festool DF 500 RQ-Plus DOMINO is a professional joining machine designed to create strong, accurate and reliable timber joints with remarkable speed and repeatability. It combines the precision of a round dowel with the flexibility of a flat dowel, using Festool's unique pendulum routing action to create clean elongated mortices for DOMINO dowels. Ideal for cabinetmaking, furniture production, joinery, frames, panels, mitres and small-section work, the DF 500 makes it easier to produce perfectly aligned joints that are stable, strong and secured against rotation from the very first DOMINO.

Product highlights

• Unique DOMINO joining system: Combines the strength of mortise-and-tenon joints with the speed and flexibility of dowel joining.
• Pendulum routing principle: The cutter rotates and swings at the same time to create a clean, accurate elongated mortice.
• Rotation-proof joints: The oval DOMINO shape secures the joint against twisting from the first dowel.
• Fast positioning: Four integrated stop pins help position repeat dowels quickly from a reference edge or previous mortice.
• Flexible mortice width: Route a first snug-fit mortice and wider follow-up mortices to allow easy alignment during assembly.
• Wide dowel compatibility: Suitable for DOMINO dowels from 4 x 20 mm to 10 x 50 mm.
• Adjustable routing angle: Routing angle can be adjusted from 0 - 90° for mitre joints and angled work.
• Dust extraction ready: 27 mm dust extraction connection helps clear chips from the mortice for more accurate work.

Features

• 420 W motor: Provides reliable mains-powered performance for accurate DOMINO mortising work.
• 25 500 min⁻¹ idle speed: High cutter speed supports clean mortice routing in suitable timber and board materials.
• Preset routing depths: Depth stops of 12, 15, 20, 25 and 28 mm are matched to common DOMINO dowel sizes and panel materials.
• DOMINO cutter range: Compatible with 4, 5, 6, 8 and 10 mm DOMINO groove cutters.
• Routing height adjustment: Adjustable from 5 - 30 mm for accurate positioning on different workpieces.
• Mitre routing: Fence angle can be adjusted from 0 - 90° for mitred frames, angled joints and furniture work.
• Plug-it cable system: Removable mains cable with safety lock for quick tool changeover and easier storage.
• FastFix cutter change: Makes changing DOMINO cutters quicker and more convenient.
• CLEANTEC connection: Integrated bayonet fitting for secure connection to compatible dust extraction.

Benefits

• Stronger furniture joints: DOMINO dowels create secure, stable and rotation-proof connections for furniture, frames and panels.
• Faster alignment: Built-in stop pins and preset routing depths reduce measuring time and make repeat work easier.
• Cleaner assembly: The first snug mortice positions the joint accurately, while wider follow-up mortices allow easier glue-up alignment.
• Versatile workshop use: Suitable for solid timber, board materials, frame joints, mitres and thin workpieces from 12 mm.
• Better dust removal: Dust extraction removes chips from the mortice, improving precision and helping the cutter work cleanly.
• Indoor and outdoor joining: Compatible with beech DOMINO dowels for interior use and sipo DOMINO dowels for exterior applications.
• Professional repeatability: The DOMINO system helps produce consistent joints across single pieces, batch work and fitted furniture projects.
