Cutting Metal With A Circular Saw

Cutting MetalIf you are using a circular saw you will need to use the right blade for whatever material you are cutting. As well as using different blades for cutting metal and wood, you might even need a different saw entirely – many wood cutting circular saws have an open motor housing. By comparison, a saw designed to cut metal has a collection bin which stops metal chips from getting into the machinery. If you don’t have the means to get hold of a specialist metal cutting saw and need to use a wood saw to cut metal, only ever use a 7.25 inch blade, ideally a worm drive one which will give you extra torque. Remember that although most saw blades are installed with visible labels, worm drives are actually mounted on the opposite side.

You actually need different blades to cut different types of metal. A carbide tipped abrasive cutoff wheel will do for copper or brass, or any other non-ferrous metal like lead or aluminium. Carbide tipped blades also last up to ten times longer than ordinary steel. You’ll also want to vary the pitch and design of your blade depending on the metal thickness. For thin metals you need a higher tooth count than for thick metal sheets. The packaging of the blade will specify the material and thickness which the blade can cut – if in doubt it is better to contact the manufacturer to be sure.

A lot of home improvement stores only carry circular saw blades which are suitable for cutting wood, so you might need to have a look online or visit a specialty tool store. Don’t automatically go for the cheapest option – quality tells and you might end up with shoddy results. Alternatively, you can buy metal online from various companies who already have the specialist equipment needed to handle it. Some metal suppliers will also allow you to order specific metals cut to a given size and shape which saves on you having to do this yourself.
