Table Saw Blade Information

bladeI always repeatedly talk about how useful table saws are and how much work they can do for you if you use them smartly. I’m going to assume you know what you’re doing and have decided on a particular type of table saw or maybe already have your own.

Changing your table saw blade is essential and I am going to guide you through what you need to know.

It’s crucial. This short article I put together should teach you what you need to know and what to avoid when buying a new blade for your power tools.

Blade Material

For cutting plywood and hardwood you’ll want metal blades, but if you want to cut through some even harder materials you’ll want different materials. The harder ones have a metal core but with a harder material on the outside.

For example, the teeth on blades that cut through wood are usually made out of steel or carbon steel, which helps their strength. There are also masonry blades, this type has diamond-tipped teeth, and then there is the types that are made to cut through steel and other metals. These blades have teeth that are made with hardened metal or tungsten carbide for strength.

Blade Adjustments

Newer saws allow the blade to be adjusted in different ways. It can be adjusted both vertically and by changing its axis.

If you expose more of the blade, this changes the depth of cut and is wat a vertical adjustment does. This is good for thick pieces of wood, as well as for other cuts. When adjusting the axis of the blade, you can make cuts at certain angles, including making bevel cuts.

Before deciding on the one for your saw, you need to consider several characteristics such as the diameter, what it’s made of, what it can cut, how many teeth, speed, and price. Of course, it needs to fit your table saw as well.

In the past, saw blades were meant to cut only wood, but they can cut through plastic, metal and other materials. Remember that most blades are still fabricated out of metal, but some also have special alloys and materials in the teeth and other materials in the body.

Blade Sizing

Table saw blades are sized in a few ways. Their outside diameter and the diameter of the mounting hole are the most common. Standard sized blades for table saws are 8-12 inches in diameter, but there are ones that are 3 3/8 inches in diameter, as well as larger ones that are 30 inches in diameter. The bigger sizes are designed for commercial use.

By far, the easiest way to know which one is best for your table saw would be to look in the instruction manual. There is a fixed amount of space inside the arbor, so you can only fit a certain size of the blade.

The central arbor hole on most blades for best rated table saws are 6/8 inches in diameter, but there are certainly other ones too. If the diameter and the arbor fit good, you are on the right track.

RPM

The max speed is usually measured in RPM (revolutions per minute). One thing you need to be aware of is that the speed of the table saw must never exceed the speed of the blade or there will be trouble. The blade to break apart due to centrifugal force if this is not followed.

Types

There are two basic types of table saw blades which are crosscut and rip blades. Rip blades have fewer teeth and larger gullets, this means there’s more room to get out the dust and shavings. These blades are designed to cut with the grain of the wood, although they cut faster and leave a rougher pattern.

If you want finer cuts, a crosscut blade is the better option. The cut will be much smoother because the teeth have less space for removing chips and because there are more teeth the rate is much slower.

Blade Teeth

The more teeth it has, the smoother the cut will be. Most blades have between 20-80 teeth, expect for blades that were made to cut through certain materials.

Should you go with fewer teeth or more? More teeth will ensure that the cut is smoother, but also means the cutting will be done slower. Fewer teeth make for faster cutting, but the cut will be rougher.
