A circular saw blade consists of teeth by which cutting of different Material is being done using a spinning motion. They are fitted in various power saws depending on the material to be cut.
Here are a few basic things one should keep in mind before buying Circular saw Blades.
- Basically, to cut different materials, different sets of circular saws are available. You need to be sure of the material you are about to cut before choosing a type of circular saw blade. And you should also be sure that the blade must fit in your saw.
- As there are various types of circular saw blades and each of them is designed to cut material of different specifications, where also they have to work with particular power saws. There are few specifications you need to put a check on. Like you need to compare the blade diameters, blade type, and capability to fit in power saws. Here are few specifications in diameters, blade type and capacity to cut materials.
- Primarily Handheld circular saw uses smaller blades of 4 1/2 inches to 7 1/4 inches in diameter. And these blades are specifically carbide-tipped.
- The tile saw mostly uses 7-inch or 10-inch diamond blades.
- Compound meter saws use blades of 10 inches or 12 inches in diameter and when they are used for handheld, they are carbide tipped.
- The metal-cutting chop saws are also called abrasive saws or cutoff saws and are of 14-inch silicon carbide or aluminum oxide abrasive blades.
- Circular saws are known for making quick straight cuts across the boards or along the board length. And you can also use circular saws to have bevel cuts.
- Safety Precautions: This tool has only one serious drawback that it can be dangerous. So, all the models come with blade guard above the saw base, which protects you from material thrown from the sides and top of the tool at high speeds. Be careful while using a circular saw and wear proper ear, eye, and chest protection gear.
Types of circular saw blades for cutting different materials and their specifications one should know:
Standard circular saw blades are generally preferred to cut wood or wood composites. Number of teeth on the blade helps you to determine its speed, type, and finish of the cut. Blades with lesser teeth cut faster than the more ones, but those with more teeth give a better finish. It gives a straight cut, with less vibration.
- Rip-cut blades cutting with the woodgrain, generally have fewer teeth (16 to 40). Those teeth are designed to cut aggressively, and those deep gullets provide you good chip removal.
- Crosscut blades cutting across the woodgrain having between 40 and 80 teeth designed for specific clear cuts.
2) Turbo Rim Blade
Turbo-rim blades are basically diamond blades and are similar to continuous-rim blades but like a serrated rim that usually cuts materials, like brick and concrete. Turbo rim blade cuts more aggressively than those continuous-rim blades but doesn't usually give a clean finish. Some of them work for dry cutting only, while others are appropriate for both wet and dry usage.
3) Continuous Rim Blades
Continuous-rim blades are actually a type of diamond-edged blade and they are also known as diamond blades which are designed for materials like tile and slate. Diamonds are fixed on the edge of the blade which cuts through the material. These blades generally give a clean cut. Some of them are used for dry-cutting and some are used for wet-cutting and some of them work on both wet or dry usage.
4) Segmented Blades
The segmented blades also cut with diamond edges but they have a rim which is divided by the gullets similar to those of standard blade. These segments give the most aggressive kind of cut of the diamond blades. These blades usually cut more faster than those other types and can also handle very tough materials like bricks and concrete. It leaves a rough finish on the surfaces.
5) Abrasive Blades
Abrasive blades usually cut materials like concrete and bricks. And few abrasive blades are perfect for metal-grinding (cutting) applications. For example, diamond blades cut with abrasive materials instead of teeth (they don't have teeth).
6) Stacked Dado Blades
Stacked dado blade sets are actually wood-cutting accessories which include two circular saw blades, several chipper blades, and shims. Generally, by stacking the blades or making combinations of these blades, chippers, and shims, you can easily cut out grooves of different widths.
