Power saws are fantastic machine tools, but they can be bewildering. There are so many different types of power saws in a variety of categories and subcategories that remembering what each one does becomes difficult. This article serves as a sort of “comprehensive guide” to explain the world of various types of power saws.

What Are Power Saws?

A power saw is a machine tool that makes use of a blade to cut through solid material. As adhesives and welding become more popular, there’s less need for blades in many applications, but there is still plenty of work for the classic “cutting machine.” Besides the classic “metal-cutting” power saw, there are also applications for wood- and plastic-cutting blades.

Types of Power Saws

Different types of power saws can be grouped into six categories: woodworking power saws, metal-cutting power saws, abrasive-cutting saws, water-cutting power saws, and pipe-cutting power saws.

Woodworking Power Saws

Woodworking tools are the best known in the world, and there is a wide range of machines available. Each one works with a particular material and cuts the material in a particular way. Here’s a look at some woodworking power saws:

Chainsaws: Chainsaws are the most common power saw available. They’re powered by an internal combustion engine and use a thin blade to cut the wood into smaller, more manageable pieces. Chainsaw blades can be dangerous if used incorrectly or with inadequate safety gear, but they’re relatively easy to control when used correctly.

Panel Saws: These are the most common woodworking power saw. These use circular or band blades that rotate at a high speed, and the blade is drawn through a piece of material to cut it into thin slices. In other words, this machine uses a sort of “meat cleaver” approach to cutting instead of a slicing motion.

Circular Saw: This is a handheld machine that spins a thin blade vertically around an arbor so cutting can be done from left to right. It has a corded electric motor that runs at a high rate of speed. Cordless circular saws are also available, but they run on batteries and can’t match the power output of their wired counterparts.

Jigsaw: Much like a handheld circular saw the jigsaw uses a thin blade to cut through the wood in a left to the right direction. Jigsaws are traditionally stand-mounted and might be handheld at times, but they’re always electrically powered and spin the blade at a high speed.

Band Saw: A band saw has a horizontal or tilted work table that allows the material to move into the cutting area. The blade runs horizontally back and forth across the material. Band saws are typically used for cutting curves or bowls into the wood.

Table Saws: This machine sits on a work table and, as the name implies, is generally operated from above. It’s much larger than other saws and spins a large blade at high speed. The blade doesn’t move left to right as it does with other saws; instead, it moves up and down.

Miter Saw: A miter saw is a table saw with an adjustable worktable that can hold material at angles other than 90 degrees, making it easy to cut pieces for framing or roofing purposes. Miter saws are very common in the construction world, and many people prefer them over table saws because they’re more compact and have a smaller learning curve.

Metal-Cutting Power Saws

There are several types of power saws that cut metal, but the basic idea is to spin a blade at a high rate of speed so it can pass through a material with less resistance. Here’s how they work:

Band Saw: Similar to the band saw used for cutting wood, a band saw that cuts metal is typically even more rugged. Materials such as structural steel and iron can be cut using a metal-cutting band saw.

Chop Saw: Chop saws are capable of making very accurate cuts, but the blade is small and rotates at a very high speed. The end result is very clean-cut, making this an excellent choice for home repair work.

Cut-Off Saw: The cut-off saw is commonly mounted to the floor or benchtop and can make cuts of up to ¾ inches thick in steel. The solid cutting wheel spins at 3600 RPM, but there are also chop saws that have smaller blades that rotate at high speeds.

Turret Punch: A turret punch machine uses a very small saw blade to cut through the metal, which is mounted on an adjustable turret. The process allows for precise cutting in a short amount of time.

Abrasive-Cutting Saw

Sanding belts are the most common type of abrasive cutting saw, but there are also wire brushes and diamond tools available for wet and dry cutting. These machines are typically used for metalworking, but they’re also capable of cutting ceramic materials and hardwoods.

Water-Cutting Power Saws

Also known as waterjet cutter saws, these saws use a pressurized stream of water to cut the material at very high speeds. This process is perfect for cutting glass, metal, stone, and other hard materials.

Pipe-Cutting Power Saws

Pipe-cutting saws are similar to wire-cut machines in that they use a circular saw blade to cut through the material. However, pipe-cutting saws spin at a much higher speed and can make very precise cuts when needed. This makes them perfect for anyone who needs to cut tubing down to size on a regular basis. Typically, pipe-cutting saws are large and extremely powerful.

Final Thoughts

As you can see, there is a power saw to suit every job requirement. Each machine has a specific function in the woodshop or on the building site, whether it is for cutting metal or making precise cuts in hardwoods. The purchase of a few different types of power saws will not only save you money on replacement blades but will also make it easier for you to accomplish your next project.

After learning more about how all of these machines operate and what they’re used for, you’ll be better prepared to make an informed purchasing decision when it comes time to add one to your tool collection.

Saw Teeth: How To Choose The Right Saw Blade

Changing the saw blades on time is necessary for ensuring that your tool cuts correctly without damaging the workpiece, and it minimizes the danger of injury to the user. If you’re shopping for replacement blades for your saws, you’ll need to think about the kind of saw you have and the sorts of cutting jobs and applications that it will be used for. Do you intend to utilize saw teeth for ripping or crosscutting?

Continue reading this article to find out about saw teeth and how can you choose one before buying!

What Are Saw Teeth?

The teeth on a saw blade are designed to cut through materials by removing small pieces of the material as it is moved forward. They do their work even if they aren’t aligned like those on a handsaw, but make sure you choose blades with closely spaced teeth for crosscut and coarse-tooth blades for rips; otherwise, your saw will not cut correctly.

What Type Of Saw Blades Are There?

Parallel grind

The “teeth” of a parallel-ground blade are ground to an angle of around 20 degrees so that the thickness of the blade remains the same along its entire length. If you need a smooth, ultra-clean cut, multiple ATB teeth alternate with comparatively larger gullets to remove sawdust without interfering with the cutting action.

Hook tooth

These blades are used on a table saw, miter saw, or radial-arm saw to make cuts with the grain. The hook angle on this type of blade is increased so that it can push the wood up and out without chipping or splintering when it leaves the cut.

Raker tooth

A raker tooth has fewer teeth than an ATB blade but they’re set to the same angle. That means that there are large spaces between each raker to remove sawdust quickly. These are designed for cutting end grain or short cuts on a table saw, miter saw, or radial-arm saw.

What You’ll Want To Evaluate When Choosing The Right Saw Blade

1.    The number of teeth on the blade: Blades with more teeth do a much better job at cutting and reducing your materials to pieces, but they will also cost you more money;

2.    The pitch of the blade: The pitch is the measurement between each group of two consecutive teeth; for example, a 10-inch blade with 8–10 inches per inch (PI) has 5.5 teeth in every PI. A larger pitch allows you to cut through dense materials more easily;

3.    The shape of the tooth: The most common tooth shape is the “ATB” which stands for “Alternate Top Bevel” and means that one side is flat while the other has a sharp angle. It’s a good choice for both crosscutting and ripping because it can cut with or against the grain of your material. You should also select blades based on their gullets. The gullets are the vital spaces between teeth that allow for effective sawdust removal and decrease the blade binding.

4.    Recommended uses: Different saw blades will last longer and cut better if they’re used for specific purposes; for instance, 14-inch wood cutting bandsaws require a very narrow thickness of kerf (the size or width of the slot or cut made by a saw on a workpiece), so they need to use thin and flexible blades with fewer teeth.

5.    Blade type: There are three types of saw blades that you can choose from – parallel grind, hook tooth, and raker tooth – depending on the material that they’re used for cutting; these three types are explained here.

6.    The cost of the blade: You can spend anywhere from $2 to over $100 for a saw blade, depending on what type you’re looking for and how long it will last, but consider that the more expensive blades offer faster cutting speeds and longer life.

7.    Blade compatibility: Some blades are made for specific saws and can’t be used on others. Make sure that the blade you’re considering is compatible with your machine. In addition, look into finding a blade type that will fit or replace the current one of your saw, as this saves you from having to spend more money on a completely new tool.

8.   Soft-start motor: If you’re using your saw on materials with higher densities, such as plywood and MDF, a soft starting blade will save you time by preventing the blade from grabbing the material right away.

9.    Blade safety features: Some safety features to look for in a blade include an automatic brake that stops the blade as soon as the saw comes out of your material, and a riving knife or kickback pawl to stop unintentional contact with the blade.

Why You Should Buy Saw Teeth?

  • Get the job done quickly: Saw teeth are designed to cut materials down in size, so they make it much easier for you to complete your projects;
  • Protect your fingers and hands: There are lots of blades that have safety features that prevent injuries if you accidentally come into contact with them while operating machinery. Furthermore, manufacturers now put technology into the saw teeth, such as a soft-starting motor and a system that triggers an automatic brake if your finger comes too close to the blade;
  • Save money: Saw teeth will last for years – they only get duller if you don’t maintain them – so it’s safer and more economical to buy new ones instead of buying a whole new saw.
  • All in all, having the right saw teeth for your machine will work wonders at getting the job done quickly and safely. Investing in better-quality blades can really help to boost your productivity so you’ll get through tasks much quicker without hurting yourself or damaging the equipment.

Final Thoughts

Saw teeth are definitely worth your money. Also, the right saw teeth will save you time and keep your fingers intact. If you’re looking to buy some new saw teeth, look into how they work with your specific material type, what kind of safety features they have, and what sort of a price you’re looking to spend.

In addition, if you have an existing saw but the teeth need replacing, check to see whether you can buy new blades made exactly for your machine, or if it would be better to simply find an upgrade that will fit on the one that you currently own.

Look into all this information when shopping around for a new blade so that you get the right tool for the job!
