Saw blades with less teeth move the wood faster furthermore blade with more teeth offer a smoother cut. For example, a 10" blade considered for ripping wood usually has fewer than 25 teeth plus are intended to the move the material quickly through the machine with the grain of the wood, this way you don't have a lot of tearout or none at all.
Alternatively a crosscut blade is well thought-out to give you a even cut and crossways against the grain of the wood without any tearing or splintering. Between 60 and 80 teeth are found on the crosscut blade. Remember, moving less material, each tooth comes in contact with the wood less and this means a crosscut sharp edge makes numerous additional single and smoother cuts than the tipping blades. A polished finish will appear on the wood if using a good quality crosscut cutting edge.
The Hook Angle
Ed's Custom Woodcrafts
The hook angle refers to the angle at which the teeth will engage the material being cut. A high or positive hook angle means the outermost tip of each tooth will engage very aggressively, whereas a low or negative hook angle causes each tooth to take a less aggressive bite.
The space missing from the blade plate in front of each tooth, which allows for chip removal, is called the gullet. In the crosscutting blade, the chips are fewer and smaller per tooth so the gullet is much smaller. In the ripping blade blades the rate is much faster than the crosscutting action and the chips are bigger so therefore the gullet needs to be bigger to accommodate the larger amount of material coming through it.
Amount of Teeth
VARIOUS STYLES OF SAWBLADE
Choosing the correct sawblade
Its not all that complicated, really. In order to put together a top rate saw blade collection of oyur own, you are required to identify a small amount about what diverse blades do and what distinguished the top-quality from the cheaper ones. Once you figure this out, you'll be able to decide the blade that is best for the type of woodworking you will be doing and the budget you can afford.
There are blades that are intended to do a number of things. Some blades are for crosscutting wood, ripping wood, cutting veneered panels and plywood, cutting melamine, cutting non-ferrous metals and cutting plastics and laminates. Combination blades and general purpose, these blades are for using two or additional kinds of cuts. The amount of teeth, the gullet, the hook angles and the tooth configuration all determines how good the saw blade is. (See images above).
There are many things to consider when choosing a saw blade - making safe, smooth cuts with your radial arm saw, table saw; compound miter saw or chop saw depends on having the correct blade for the tool and, for the kind of cut you would like yo make. Performance varies from blade to blade and presently, not a lack of them in the stores today, so choose wisely.
