A circular saw is either a hand held or table mounted tool used for cutting many types of materials such as wood, plastic, metal and masonry. All circular saws have a disc or blade with teeth on their edges.
Blade Types:Generally speaking there are four major categories of circular saw blades. Combination saw blades are designed to cut both rips and crosscuts and are the most common type of circular saw blades. Unless you have two circular saw blades available at all times, it would be more than a nuisance to switch from a rip to a crosscut blade every time you change the cutting direction.
If you want to know which blade to use for a specific project or are just looking for an overview of the types of blades that exist, here we have all the information you need about circular saw blade types. One of the most obvious features of any circular saw blade that will be immediately recognizable even to someone who has never used a circular saw in their life is the number of teeth. They are a good choice if you need one blade for a variety of uses, but if you need a blade for a more specific job, you’re better off buying a specialist blade for that application.
what is circular saw blade Related Question:
What is the difference between circular saw blades?
Teeth: The number of teeth indicates which type of cut it’s best for. Blades with fewer teeth (18 to 30) cut faster and cost less than higher-toothed options; they’re ideal for making rip cuts in wood. Blades with a higher tooth count (60 to 80) are better for crosscuts in wood because they produce a smoother edge.
What is a circular saw and what is it used for?
The circular saw is perhaps the most commonly used saw today, used extensively in both professional construction projects and DIY home improvement. This power tool uses a round metal blade edged with sharp teeth to cut an array of material such as woods, metals, cement block, brick, fiberglass, plastics and slate.
How do I identify a circular saw blade?
Most circular saw blades are carbide tipped, and the orientation of the teeth determines the blade’s primary use. Flat-top (FT) teeth are best for ripping hard and soft woods, while blades with alternating top beveled (ATB) teeth are better for crosscutting.
Can I use any circular saw blade?
Your saw manual should provide information on compatible blades, but here are some quick tips. Handheld circular saws typically accept blades 4-1/2 inches to 7-1/4 inches in diameter. The teeth are often carbide tipped to stay sharp longer. Tile saws most often use 7-inch or 10-inch diamond blades.
What type of blade is best for cutting wood?
For most construction work, a 24-tooth general use blade is sufficient. That blade is very aggressive and will help you rip and cross-cut lumber and sheet goods quickly and with a high degree of accuracy. With a 24-tooth demo blade, you’re getting work done quickly, but you won’t get a near-finished edge.
What can I cut with circular saw?
With the right blade, a circular saw can be used to cut framing lumber, sheet goods, roofing, metal, masonry, and more. A powerful saw can be a major time-saver during demolition as well. Once you get used to using your circular saw, you can even use it to cut curves, like I did on my backyard deck.
Can I use a jigsaw instead of a circular saw?
Although a jigsaw can be used for most of the tasks that a circular saw can perform, including straight cuts and cuts on a tilt, the jigsaw uses that really take advantage of the tool’s qualities are jobs such as kitchen fitting and joinery, with their frequent need for complex cuts.
How do you use a circular saw without a table?
Fit your circular saw with an edge guide. Set the depth of the blade accurately enough for it to go through the wood and not cut under the surface. Place the guide on base of the circular saw lines and markings you made earlier on the wood. Ensure that the saw is free to move, and the power cord is not entangled.
Do all circular saw blades fit all saws?
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.
What are the 3 basic types of circular saw blades?
They are: Rip Blades, Crosscut, Combination and Specialty blades. Ripping saw blades are designed primarily to achieve a smooth, clean and safe cut when ripping wood or cutting in the same direction as the wood grain.
What type of blade is best for circular saw?
Mostly, a 24-tooth circular saw blade is preferred by many people, especially if you have to cross-cut lumber and sheet materials. The 24-tooth blade is good enough for you if the diameter is 7¼”. However, as the diameter increases, you should also consider looking for circular saw blades with more teeth.
How many teeth should my saw blade have?
TPI is the number of teeth the blade has per inch. If you’re looking to cut wood or other soft materials, you’ll need a blade with a TPI of 6 up to 20. For harder materials like metal, a TPI between 14 up to 36 is more suitable. The number of teeth can be found on the blade.
Are Diablo blades worth it?
Diablo blades are available in a wide selection of sizes and styles and are easy to find online and locally at Home Depot. The consensus is that Diablo saw blades balance great quality with excellent value, and are a good choice when replacing or upgrading the OEM blades that are often bundled with new saws.
Is more teeth on a saw blade better?
More teeth means a smoother cut, fewer teeth means that the blade removes more material. Crosscut blades have more teeth and make smoother cuts across the grain of the material, rip blades have fewer teeth, are optimized to cut with the grain, and remove a lot more material.
Can I put a metal cutting blade on my circular saw?
Only blades and discs specified for cutting metal should be used. These professional circular saw blades are perfect for cutting through aluminium, copper, lead and other non-ferrous metals; while these diamond cutting discs will make light work of cutting through stainless steel.
