It’s important to remember that each blade type is designed to make certain types of cuts for a reason. They are engineered specifically for that particular cut and may not work well to make other kinds of cuts in other types of material. For instance, a crosscutting blade shouldn’t be used to make rip cuts. It can be unsafe to use the incorrect blade for certain tasks, as the blade teeth and thickness may not be sufficient to cut certain materials and could cause problems during the cut. Always use the appropriate blade for each type of material.
Woodworking Circular Saw Blades
Woodworking saw blades are round circular saw blades that are designed to cut various types of wood, including lumber, plywood, softwood, hardwood, panels and laminates. They can be used in various applications, depending on the type of wood you are cutting and the kind of task you are performing. Blades come in a variety of sizes and can be made of various materials to accommodate different uses.
Types of Woodworking Circular Saw Blades
For cutting plywood. The blade has numerous fine teeth for a better, cleaner cut.
For cutting parallel to the wood grain. This blade has fewer teeth and a large gullet.
For cutting across the wood grain. This blade has more teeth and a small gullet for smoother cuts.
Combination Blade (All-Purpose Blade)
For cutting across or parallel to the wood grain. Great for all-purpose wood cutting. If you need a blade for general use, this is the best blade for you as it can be used for a majority of woodworking applications.
Fine-Tooth Finish Blade
For making extra smooth cuts.
Hollow Ground Blade
For making smooth cuts across the wood grain.
For making grooves, dadoes and rabbet cuts in lumber.
Thin Kerf Blade
For cutting dimensional lumber.
For cutting paneling, veneer, plywood, laminates and plastics
The DEWALT® 10" x 40 Tooth General Purpose Woodworking Saw Blade is quality made and carefully designed to take on a variety of woodworking applications. It features large, precision-ground C4 micro-grain carbide teeth with fine-grit diamond wheels so each tooth plane the wood for an exceptionally smooth finish. Works with circular saws.
Framing Saw Blade
Try the Freud Diablo 7-1/4" x 24 Tooth ATB Carbide Framing Saw Blade with Diamond Knockout Arbor for a blade that's tough enough to take on heavy duty construction and remodeling projects. Equipped with a thin kerf and PermaShield coating to prolong blade life, its laser-cut stabilizer vents reduce noise, vibration and heat build-up, allowing for more precise cuts. Works with portable and low-powered circular saws.
Finishing Saw Blade
Count on Freud's 7-1/4" x 40 Tooth ATB Finishing Saw Blade with Diamond Knockout and PermaShield Coating for lasting performance on construction and remodeling projects. This advanced laser-cut blade has a thin kerf, making it an ideal pick for portable and low powered saws. In addtions, the PermaShield Coating helps prevent gumming and corrosion, prolonging blade life and enhancing performance. Works with portable and low-powered circular saws.
General Purpose Blade
Opt for the Bosch 12" x 60 TIP General Purpose Woodworking Blade for a quality, all-purpose blade. Designed to produce clean cuts in a variety of operations, it's ideal for ripping or crosscutting soft and hard woods, along with wood products. Works with circular saws.
Chipboard/OSB Woodworking Blade
Bosch's 10" x 80 TPI Chipboard/OSB Woodworking Blade is designed to last. It's capable of fast sizing of chipboard/OSB sheets and stacked sheets. It's also useful for cutting laminates, plastics, PVC, acrylics, polyurethane and similar synthetics. Works with circular saws.
How thick a blade is. The thicker the blade is, the longer it lasts and the more it can be resharpened. Blades with a thin kerf tend to be sharper and cut faster. Thinner kerf blades require less work from your motor since they cut less wood. If your saw doesn’t pack a large amount of power, thinner kerf blades are the best choice. However, thin kerf blades tend to cut rougher edges than thicker kerf blades.
The sharp points on the blade. The more teeth a blade has, the cleaner the cut. Fewer teeth make for a rougher cut. The number of teeth depends on the blade. Some blades have only 24 teeth while others can contain up to 60 to 80 teeth.
- Flat Top: Used in ripping hard and soft woods
- Alternate Top Bevel: The teeth alternate between a right-handed and left-handed bevel. Perfect for smooth cuts during crosscutting of natural woods and veneered plywood
- Combination Tooth: Perfect for both crosscutting and ripping
- Triple Chip Grind: Cuts laminates, plastics, MDF and non-ferrous metal
- High Alternate Top Bevel: Used for extra-fine crosscutting
There are five types of teeth:
The curved area between two saw teeth. Serves as an area for chip removal while you are cutting. Ripping blades tend to have deeper gullets to accommodate the bigger chips that are produced while cutting. Crosscutting blades have a smaller gullet because they produce smaller and fewer chips.
A grooved area of the blade (typically on larger blades) designed to create an avenue for built-up heat on the blade.
The part of the blade behind the teeth that provides added support to the teeth.
Angle of the saw tooth in relation to the center of the blade. Blades can have a negative, positive or zero degree hook angle:
Negative Hook Angle:
Saw teeth tip away from the direction of the blade rotation. Blades with a negative hook angle slow the feed rate during the cut
Positive Hook Angle:
Saw teeth tip toward the direction of the blade rotation. Blades with a high positive hook angle cut aggressively and have a fast feed rate.
Zero Degree Hook Angle:
Saw teeth are in line with the center of the blade
Horizontal cut made in lumber.
A cut that is parallel to the wood grain.
Before You Buy
There are several things to consider before buying a woodworking circular saw blade. Always consider the diameter needed, the kerf, and the arbor size. The type of wood is also important (see the types of blades list above). Also think about if you want any sort of coating on your blade. Many blades are coated to prevent corrosion and wear while maximizing blade performance.
Are coated blades worth the extra money?
It depends. Do you care about what the wood looks like after cutting it? Many times, blades can leave burn marks if they are too hot and overheat while they are used to cut. If you want to avoid burn marks or you are concerned with the appearance of the wood, spend the extra money on a coated blade. The coating helps reduce friction and heat, which means the blade is less likely to leave burn marks on the wood. If not, stick with a regular blade without coating.
What kind of saw blade should I use?
It depends on the application. If you are making rough cuts, opt for a ripping blade. If you want a more precise, finer cut, go for a crosscutting blade. If you need a blade for various cutting applications, go for a combination blade. Also, there are blades designed for cutting certain types of wood, like plywood (plywood blade), lumber (dado blade), dimensional lumber (thin kerf blade).
