If you’re new to woodworking, finding the right blade can be confusing and expensive, both in the cost of the blade or destroyed wood. Below you can find the types of blades most commonly used on table saws. Each have specialized uses and may solve many of the problems you may run across, such as burning, rough edges, etc.
There are several types of table saw blade teeth. See below for the different types of blades, and their best uses.
On Flat Top (FT) blades, the teeth are not beveled, each faces the same direction. These are great for ripping hard or soft woods. These blades remove wood quickly, and are great for your starter pieces. If you are making joinery cuts with an all purpose blade or ATB blade for joinery, you may find that there is a lot of sanding to make smooth fittings. Try using an FT blade like the Forrest 2-Piece Finger Joint Set. It has flat teeth that make square fittings.
ATB Blades have alternative bevels and are great for cross cutting. There are more teeth so this blade will cut slower than FT blades, but the cut will be much cleaner, therefore you will have less finishing work. Both Freud and Forrest have excellent versions of ATB blades.
The combination blade has groups of four alternative top bevel and one flat top. This is great for general wood applications. Most work that you do, this blade will be very effective. Diablocomb blades are very good.
Hopefully this guide will help you choose the best blade for your projects. May you have success in all that you do.
