Combination Woodworking Machines: Planing, Sawing and Moulding in One Unit

The simplest models are 2-in-1 planer-thicknessers (jointer and thicknesser), while universal machines add a circular saw, spindle moulder, slot mortiser and sanding for up to 5–7 operations. Choose only the operations you really need, and for a single operation compare dedicated machines as well. Read how to choose a thicknesser and jointer and how to choose a table saw.

Household and semi-professional combination machines are usually rated at 1500–3000 W and run on 230 V, while workshop models deliver 3–5.5 kW or more, often on 380 V three-phase power or with a separate motor for each unit. Before buying, make sure your workshop supply can handle the starting current. See how to choose tool power (W) and connecting single-phase and three-phase motors: star, delta and capacitors.

Planing width sets the maximum board width: 200–260 mm on compact models and 300–410 mm on professional ones. Also check the maximum thicknessing height (usually 120–230 mm), the depth of cut per pass (2–3 mm) and the length of the jointer table, which determines how straight long workpieces come out.

The saw unit of a combination machine usually takes a 200–315 mm blade, giving a cutting depth of 50–100 mm. Pay attention to blade tilt, a sliding carriage table and the rip fence. For choosing a blade, read how to choose a circular saw blade.

Switching between modes means raising the jointer tables, moving guards or changing fixtures, which can take from 1 to 10 minutes. If you change operations often, choose models with quick clamps and tool-free changeover, while units with separate motors let you work without resetting the machine.

Cast-iron tables are heavy, damp vibration well and stay flat for a long time, while models with aluminium or steel tables are lighter and easier to move. A rigid steel or cast-iron frame and installation on a level base are important for accurate sawing and planing.

Planing and sawing produce a large volume of chips, so check the diameter of the extraction port (usually 100–120 mm) and connect it to a chip extractor or industrial vacuum. During dusty work, protect your airways as well. Read how to choose a vacuum cleaner: household, workshop, industrial and washing and how to choose a respirator.

Choose a model with guards over the blade and cutter block, a riving knife, motor brake, emergency stop button and no-volt release that prevents restarting on its own after a power cut. Connect the machine to an earthed socket through a circuit breaker and work with safety glasses and ear protection. See how to work safely with stationary machines, how to choose electrical protection and switching devices and how to choose personal protective equipment.

The cutter block usually holds 2–3 knives that are periodically sharpened or replaced, and some models use a helical cutter block with replaceable carbide inserts. Check the availability and sizes of knives, blades, cutters and belts in advance. Read how to choose mechanical and electrical spare parts for power tools.
