There are a wide variety of coping saw blades available and sometimes it can be difficult to choose between them. Well, in the following article I'll tell you about the types of blades and what you're best off using them for. Armed with this knowledge you can be confident the next time you need to buy a new blade for your project.

There are two main factors to keep in mind when you're choosing which blade to use:
The material you will be cutting
The type of cut you want to make


Material:

Metal - This will need a high-carbon steel blade and will allow you to cut curves in thin metal. Although you may find that a hacksaw is more efficient for straight cuts.

Tile - A little more specialised, you'll need a tungsten carbide encrusted wire to cut ceramic tiles.

Plastic - This blade will have helical teeth and is capable of cutting in any direction. This means you can change the direction of your cut by applying pressure in that direction without having to rotate the blade.

Wood - Nothing special here, you'll want to choose your blade based on the teeth per inch (tpi) depending on the type of cut as you'll find out below.

Type of cut:

You can break this down into two options; are you cutting straight or in a curve. As a general rule of thumb, if it's a straight cut then you'll want a coarse blade which has fewer teeth per inch (tpi), this will cut quickly and help you stick to a straight line. If it's a curve then you want a fine blade with more teeth per inch, this will let you cut tight curves but it will be slower going.

For cutting wood this translates to less than 15 tpi being a coarse blade and more than 18 tpi for a fine blade.

A word of warning though; don't be tempted by blades that are billed as being able to cut any material, so called "general purpose" blades. They probably will cut any material, I won't deny that, but the quality of the cut will be substandard compared to using the correct blade for the material. It'll be up to you to decide whether the quality of the cut is worth spending just a couple extra dollars on a specific blade -they are really cheap, so I don't recommend skimping as you're not going to save a lot!
