Used Circular Saws For Sale
Buying a new circular saw doesn’t have to be difficult. The way that circular saws are designed and built means that they have the tendency to last for very long periods of time. If you are looking for a new circular saw, you may want to take the time to track down used circular saws for sale that may still have quite a bit of life left in them, and end up costing you substantially less than a new model will. Go over some of the different areas, listed below, that you’ll need to think about when buying and using a circular saw.
Electric Brake – An electric brake is essential on any circular saw, and any tool that you are considering for purchase must contain one. The electric brake works to slow down the speed of the blade whenever you release power to the motor. This simply means that instead of continually spinning after the power has been cut off, the blade will come to a halt, making it much safer to operate.
Blade Size Capacity – Most circular saws are built to hold a few different sizes of blades. Ranging from the typical 7 1/4” blades that you will find in most applications, down to 6 ½” models that are designed for specific situations such as cutting tile, or metal materials.
Blade Shaft Locks – A blade shaft lock is a pin that goes through the a hole in the saw blade when you push the button. The pin helps to hold the blade in place so you can remove the bolt holding it on, making it much easier to change out the blades than holding the teeth with your fingers.
Types Of Circular Saw Blades
Steel – Steel saw blades are the most common type of blades that you will come across, because of their cost effectiveness. They are incredibly cheap, and work extremely well in soft woods. However, as the density of the material increases, you are going to find that the teeth begin to dull very rapidly.
Carbide – Carbide blades, and carbide toothed blades are slightly more expensive, but on average will last up to twice as long as a common steel blade. These blades can run over nails without worrying about destroying the teeth, where a steel blade will bend the teeth, and possibly warp from the excess heat.
Tile – A tile saw blade usually contain teeth that are tipped with diamonds, which helps them cut through a wide variety of tile materials with ease. They are some of the most expensive blades that you will come across, though, because of their design and the materials that they are manufactured from.
Masonry – Masonry blades are designed for cutting concrete, cinder blocks, brick, mortar, and other concrete materials. They are heavily abrasive which helps to dissipate some of the dust that you will be working around while cutting hard materials.
Types Of Circular Saws
Cordless – Cordless circular saws are finding their way onto a lot of jobsites because of their efficiency. As long as the battery stays charged, and holds a charge for long periods of time, you can easily get quite a few cuts made with a cordless saw, without having to drag out the electrical cords.
Wired – Wired saws, however, have their place in quite a few more applications because of the heavy duty nature of most construction type jobs. If you are going to be using the saw very often, you will want to go with a wired circular saw over a cordless saw.
Circular Saw Safety Tips
Tip #1: Avoid Hitting Nails In The Wood – If you suspect there may be nails in the wood that you are cutting, you want to take the time to remove them, or you run the risk of damaging your saw blade, and shooting hot pieces of shrapnel out of the wood when the blade hits them.
Tip #2: Allow The Saw To Get To Full Speed – You can avoid kickback by allowing the saw blade to get up to its maximum speed before beginning your cut into the material that you are working with.
Tip #3: Never Chuck The Guard Back – Chucking the guard back refers to inserting a block of wood into the guard, making it easy to move from material to material very quickly, but you run the risk of cutting yourself open very easily with the saw in this arrangement.
Tip #4: Do Not Force The Blade Through – If you are trying to power the blade through the material, you run the risk of having the blade slow down and kick the saw back out at you, creating a very dangerous situation for anyone around you.
