If you are cutting lengths of wood, sheets or boards use a combination blade. There are other attachments available to cut masonry, ceramic tiles and metal. Circular saws are suitable for cutting timber, plywood, MDF and blockboard. It is the ideal tool for accurate and quick straight line cuts. It is possible to buy a saw attachment to fit an electric drill.
Check the manufacturer’s guidelines, as often you can only fit attachments to the same brand named tool. Circular saws are competitively priced and can include varying cutting capacities, varying speeds, adjustable line of cut indicator, depth and angle adjustment, adjustable rip fence, remote lower guard lift lever, dust extraction facility, safety switch and saw blades.
If the wood is coated with melamine extra care must be taken to avoid chipping the surface. The cutting line should be marked on the right and wrong side, use a craft knife and score the melamine surface along the pencil line using the straight edge. For extra safety, try covering the scored melamine section with clear adhesive tape and saw through that along the cutting line.
The circular saw cutting is made as the blade rises under the wood, therefore the cleanest side of the cut is underneath. When using a circular saw, melamine and coated surfaces should be cut on the wrong side. Lay the coated surface on a bench and make sure that the area underneath the cutting section is clear, to avoid cutting anything supporting the wood. Always make sure the cable is out of the cutting region and wear a mask and safety goggles to prevent the fine dust entering the nose and eyes.
