Woodwork multi-tool buying guide

- Tenoning trolley
Why a multi-tool, and what can I do with one?
- 2/3 function multi-tool, e.g. planer + thicknesser + mortiser or table saw + router;
- 5/6 function multi-tool, e.g. planer, thicknesser, table saw, router and tenoner.
- Planing, i.e. making two faces of a piece of wood perfectly flush;
- Thicknessing, or cutting a piece of wood of a desired cross-section, after planing;
- Dimensioning, or cutting precisely sized panels or pieces of wood;
- Routing, to profile pieces of wood with a rotating tool on a vertical shaft.
- Tenoning trolley, a tool designed for creating tenons in bulk;
- Mortising machine, also for serial assembly work;
- Circular saw with scoring machine, ideal for cutting melamine or panels intended to be visible without the risk of producing splinters. Great for professional results!
- In terms of bulk, a fully extended multi-tool bench may exceed 3m in length, while the smallest models can be under 90cm;
- Smaller models weigh around 50kg but the professional machines can exceed 1 tonne.
What types of power source are there?
- Synchronous (electronically commutated);
- Asynchronous (conventional, less noisy).
How does power relate to function in a woodwork multi-tool?
- Planing / thicknessing: power dictates the machine's ability to remove material from a piece of wood easily and smoothly; this characteristic is referred to as height of pass. In addition, it affects the speed at which workpieces are processed via guide rollers onto the planing irons.
- Sawing: the more powerful the machine, the thicker the pieces you can cut - and the easier it is to cut hardwoods such as oak. Be careful not to overestimate the cutting capacity of your machine!
- Routing: again, power is everything! A more powerful router can remove more material and reduce the number of passes required to achieve the same result. A speed selector (in rpm) may be included on mid- to high-spec models, depending on the type of work (rough planing versus finishing, tool type, etc.)
- Tenoning and mortising: Ditto, power equals possibilities... greater cross-sections, mortiser speed range, tenoner cutting capacity etc.!
What info should I consider for each tool function?
Planing / thicknessing
The most important factor here is the table width. This dictates your ability to plane pieces of wood of large widths. Widths range from 150mm to over 410mm for professional machines.
Here you need to know the maximum sawing height as well as the blade diameter. Table length influences ease of cutting longer pieces of wood, but be careful that the overall size doesn't become untenable!
Routing / tenoning
There are two types of router, those which use routing cutters of different diameters (typically on smaller multi-tools) and those with a conventional shaft (30 or 50mm); the type dictates the range of tool heads you can use on your machine.
Make sure you're aware of the mandrel clamping strength so you can establish what type of mortice bits to use. A broad diameter makes for quicker mortising work.
Finally, think about how your mortising table is fitted and removed from the multi-tool, as this can be a laborious task in itself.
Comfort and convenience: a word of advice?
What about optional accessories?
- A manouevring device, very practical for putting your machine away without damaging your back!
- Servants, to process longer pieces of wood with minimal risk;
- A vacuum cleaner, a real help for the lungs and to avoid constant cleaning of your workshop;
- A shaft working kit, for the router function, to enable you to cut curved shapes etc. Sometimes it comes with the machine;
- An automatic guide, again for routing, which drives your workpieces along without you needing to push - perfect for large-volume work in safety!
