It is better suited to construction and framing work than fine carpentry but can be used for both. It is a good choice for rip cuts. This blade fits a 10 inch saw with a 5/8 inch arbor. It has a nonstick coating that helps the blade run cooler and last longer.

  • General carpentry

Ryobi Circular Saw Blades – D150 x 1.5MM

This is a case where matching the blade brand to the saw brand pays off. Ryobi’s 5 ½ inch circular saw has a 10MM arbor. Since few saws sold in this country use this size blade and arbor, looking for Ryobi 5 ½ inch circular saw blades can save you headaches. This particular blade has 18 teeth, ideal for framing and rip cutting.

Best for cutting:

  • With Ryobi 5 ½ inch circular saws
  • 2x lumber
  • Framing work where speed is needed

Best for cutting:

  • Sheet steel roofing products
  • Light angle iron
  • Other thin or light gauge metal

What we don’t like:

  • Not a blade for wood
  • Blade life isn’t excellent
  • Not as good as a dedicated chop saw if you cut lots of metal

Blade Size

First, what size saw do you have? Common circular saws include 5 ½, 6 ½, 7 ¼, and 10 ¼ inch blades. Always use the correct size blade. Using a different sized blade is a great way to spend some time in the emergency room.

Arbor Diameter

Once you know what size blade you need, check the arbor diameter. The arbor is the mounting screw on the saw that serves as the axle for the blade to rotate around. The most common arbor sizes are 5/8 inch round or diamond-shaped, but there are other sizes. Use blades that fit your arbor or your blade can wiggle, causing poor performance or accidents.

Many circular saw blades have a 5/8 inch circular hole with perforations that allow you to punch out the middle to fit a diamond arbor. If you have an odd sized arbor, it may be worth it to locate a bushing that will let you adapt your saw’s arbor to fit common sizes.


The final number you need to know is the number of teeth. Using a blade with the correct tooth count for your job will produce much better results.

Blades with fewer teeth cut faster but leave a rougher edge. The fastest cutters are 24 tooth framing blades. Blades with more teeth are slower but leave a smoother cut with less splintering. For finish work on high grade plywood, look for a blade with as many as one hundred teeth per inch.

Specialty blades are also available to cut materials other than wood. Abrasive blades are made to cut metal stock. Diamond grit blades are used for cutting tile, masonry, and concrete. There are even blades designed to cut plexiglass and plastic.


You may be wondering if you should saw blades that are the same brand as the saw. You don’t have to, but it is sometimes a good idea. For example, Ryobi 5 ½ inch circular saws have a 10MM arbor. This size is uncommon in America, and blades can be hard to find. Buying Ryobi blades guarantees you have the correct arbor size.

On the other hand, companies like Freud and Irwin specialize in making saw blades. They don’t have to worry about making motors and housings and safety guards; they just make blades. These companies only do one thing, and they do it very well.
