Well, it may be because you’ve failed to outfit your radial saw with the appropriate blade. It will be good to note that radial arm saws necessitate a different type of blade than the table saw. So, it will be helpful to be clear about that. 

A radial arm saw, of course, is a very versatile tool. Woodworkers love this tool for it is effective in cutting different types of materials. Equipped with the right blade, you can effectively use the radial arm saw for crosscutting as well as for making bevel, miter, and rip cuts.   

Essential Factors to Consider When Selecting a Blade for Radial Arm Saw

To zero in on the ideal radial arm saw blade, you need to be cognizant of some essential factors that would lead you to the right blade. Below are these crucial factors that can help you zero in on the right blade for your radial arm saw:

Blade Size

The market is awash with different types of blades. You will find blades of different sizes likewise. So, you need to know which size is appropriate for your radial arm saw. Smaller radial arm saws, of course, necessitate smaller diameter blades. The size range of radial arm saw blades is from 8 inches to 12 inches. So, make sure that you choose a blade that suits your saw well.

Blade Teeth

When choosing a blade, it will also help to look at the blade teeth. Remember that the blade’s effectiveness in cutting will likewise depend on which type of material you will cut. Moreover, radial arm saws are used for cutting woods and metals. Ideally, a blade with 40 to 60 teeth can manage to cut smoothly and efficiently. But it will be advisable to settle for blades with more teeth to ensure that you can do the cutting work well.

Arbor Size

The arbor size of the blade should also match the saw’s size. Besides, the standard arbor size is 5/8 inches. The arbor is the shaft that protrudes from the saw assembly. It is the motor shaft that allows for the blade mounting. The arbor hole, of course, is the center hole of the blade. Hence, when you choose a blade, you need to know the shaft’s diameter so that the blade you are going to buy will fit perfectly with the shaft.

Material You Will Cut

Of course, when cutting materials, the hardness of the materials will affect the effectiveness of the radial saw in cutting through the material. It will be good to note that every material has its specific molecular structure. Hence, it is but logical that different materials need different blades. 

Blades come in different hardness, thickness, and teeth number likewise. So, when cutting through hardwood, you will need an appropriate blade for the type of material you are working on. More hard materials, moreover, require blades with fewer teeth. You can also go for a universal blade that is engineered to cut through all types of materials.

Arbor Hole Size

Most radial arm saws have a standard arbor size which is usually 5/8 inches. So, you will usually buy a blade with an arbor hole of 5/8 inches to fit the shaft of the standard radial arm saw. The arbor hole is in the middle of the blade. If the arbor hole is beyond or smaller than the standard, chances are, it will not fit into the shaft of the radial arm saw. 

You can also buy blades that feature a reduction ring so that you can adjust the standard hole to a smaller diameter shaft. Hence, if the blade has a larger arbor hole, you can still use it if it has a reduction ring.

What Kind of Cut Would You Like to Achieve?

When cutting materials, you can either opt to make a precise cut or a rough cut. To achieve the type of cut you would like to have, you should be mindful of the number of teeth of the blade. Remember that the greater the number of the teeth of the blade has, the cleaner and more precise the outcome of the cut will be. If you are sawing against the grain, you might as well use a 24-toothed blade. 

If you want a neat cut result, you should go for blades whose number of teeth ranges from 48 to 72. Another rule when cutting is that you should keep at least three of the blade’s teeth biting onto the wood or material you are cutting. You can adjust the radial arm saw’s depth if you notice that fewer than three teeth strike or hit the workpiece.

Depth and Width of the Cut

Another thing you must consider when choosing a blade is the depth and width of the cut that you would like to achieve. The cut depth, of course, depends on the material’s thickness. So, before you choose a blade, it will help to determine the deepest cut that you will make on the material.

If you want to cut window frames, then you can go for 65-mm depth. But if you need more depth, you need a blade capable of more range. You will need a larger diameter blade for your radial arm saw. 

The thing is, radial arm saw can only fit one specific blade size. So, it is impossible to utilize different saw blades. Moreover, the radial arm saw has a fixed maximum cutting width.
