Peter Clothier reveals his top hints and tips for getting the best out of using rotary carving blades on grinders when used for woodcarvingError loading Partial View script (file: ~/Views/MacroPartials/cwsGalleryImages.cshtml)
Tip 1Arbortech cutters are designed to remove waste from green or dry timber, or manufactured timber materials quickly and safely e.g. for cutting profiles that cannot be cut with a bandsaw either for safety or reasons of bulk, or operating in inaccessible places, such as the centre of sheet timber materials
Tip 2There is a range of Arbortech cutters available. Most fit onto a 100mm or 115mm angle grinder. Depending on the material to be cut, there is a choice of edge materials, usually steel as in the original cutters, or tungsten toothed versions more recently on the market. The smallest cutters can be used on a rig that fits an angle grinder, or can be fitted to a Proxxon die grinder body.
Tip 3It is essential to follow safe practices, so use eye protection (face shield), dust mask and perhaps ear defenders if a long session of work is envisaged. I also recommend stout gloves as high-speed wood chips can sting, a good jacket such as a woodworker's smock, and stout shoes or boots.
I make it a personal rule that I always have both hands holding the angle grinder when it is running, and never put the tool down until the blade has completely stopped rotating. In my experience, accidents are most likely to happen when concentration is relaxed just as a job is finished.
Tip 4The Arbortech has a transparent guard which allows only the teeth cutting the wood to be exposed. It also doubles as a depth stop, allowing cuts of a set depth to be made, which gives great control over the depth of cut. The guard does restrict accessibility when the cutting face becomes deeper into the timber.
Cuts can be made straight or curved and also from side to side, giving a hollow section that can be made progressively deeper. The amount of blade projecting - with or without the plastic guard - and the bulk of the angle grinder body will have an effect on the amount of timber removed.
