Circular saw blades are designed for use with miter saws, table saws, radial arm saws, cut-off saws and standard circular saws. Many circular blades can be used interchangeably between devices. This guide will help you choose the best circular saw blades for any project you're tackling.
Safety: Always wear eye and hand protection when using circular saws.
Circular Saw Blade Types & Applications
The circular saw blade you choose depends on what you're cutting and how you're cutting it. Most manufacturers offer blades designed for specific materials, such as laminate, aluminum and plywood. The recommended applications are usually printed on the saw blades for easy identification.
Specialized blades deliver better results for the recommended use than all-purpose blades, but you'll have to change blades more often.
Combination blades are popular because they minimize downtime due to blade changes. But the crosscuts and rips can be of a lower quality than if specialized blades were used for each cut.
Which Circular Saw Blade Do You Need?
Circular Saw Blade Features
Choose the number of teeth, the angle of the tooth hook and laser-cut features on your blade to match your project's needs.
Price: Circular saw blades vary widely in price. More expensive blades usually have features that extend the longevity of the blade while enhancing performance. Inexpensive blades may dull quickly or produce rougher cuts, so make sure you weigh the benefits of each blade in addition to the initial cost.
Teeth: Blades with more teeth yield a cleaner cut. Blades with fewer teeth deliver faster cuts with rougher edges. The number of teeth should always be considered in relation to the diameter of the blade. Fewer teeth create larger gullets, removing material quickly and reducing clogging, which is important for lengthwise cuts.
Tooth hook: The attack angle of the tooth (positive, neutral or negative). An aggressive positive hook produces faster cuts but tends to increase tear out.
Expansion slots: Slots in the blade that prevent warping by allowing the metal to expand and cool when it gets hot.
Laser-cut features: Laser-cutting delivers a more precise result than stamping, enhancing accuracy and performance. Look for laser-cut bodies, arbors and expansion slots on saw blades for higher quality cuts.
Coating: Some blades are coated to prevent corrosion, friction and/or gum up, extending blade life.
