Milwaukee Sawzall Blades: What are they?
The Milwaukee sawzall blades are used to cut through metal. They have been around since the late 1800’s. There were several types of sawzalls made before the invention of the modern Milwaukee sawzall blade in 1891 by Charles Lutz. These sawzalls were made from different materials such as steel, brass, bronze, aluminum and even wood. Some sawzalls had multiple teeth while others only had one or two. The Milwaukee sawzall blade was patented in 1892 by Charles Lutz and it became very popular among carpenters because of its durability and ease of use. Today, there are many types of sawzalls available. However, most carpenters prefer the Milwaukee sawzall blade due to its reliability and ability to cut through thick pieces of sheetrock without breaking them.
Types of Sawzalls
There are three main types of sawzalls:
1) Heavy duty sawzall blades which have a hardness between 60 and 70 HRC (hardness rating).
They can easily cut through sheetrock, bricks and soft metals such as aluminum.
2) General purpose sawzall blades which have a hardness between 45 and 60 HRC.
They are not as strong as the heavy duty ones and are prone to bending and breaking. They are great for cutting wood, sheetrock, thin metal and plastics.
3) Wood cutting sawzall blades which have a low hardness of between 20 and 45 HRC.
They are usually made of tungsten carbide. They can be used on soft and hard woods, plastics, rubber and fiberglass.
What to Look for in a Good Sawzall Blade?
There are several factors that you should consider when buying sawzall blades such as the brand, the size, the type and the number of teeth. These factors all have different importance depending on what you are going to use it for.
Are you using it for wood or metal? How thick are the materials that you are going to cut? What is your experience level?
The answers to these questions will help determine which sawzall blade is right for you.
The most important factor to consider when buying any sawzall blade is the quality of the material that it is made out of because this directly affects its durability and sharpness. In general, the higher the carbon content in the metal, the better quality it is. Most blades have a carbon content of about 0.4% however the best ones on the market have up to 1.2%.
If you are using your sawzall blades to cut through wood and plastics then you might not need the best quality because these materials do not put much wear and tear on the blade. However, if you are cutting metals, you should get the best quality one that you can afford because it will retain its sharpness for much longer.
The size and number of teeth of the blade are also very important. The size is usually measured in millimeters and the more teeth a blade has, the more cuts it can make before it needs to be replaced. The size of the blade affects how deep it can cut. Blades that are 40mm and below are usually for wood and plastics. 41-50mm are for electrical applications and trim work.
51-60mm are medium duty blades that can handle most materials. Finally, those that are 61mm and above are heavy-duty blades that can chop through brick, concrete and metals. The number of teeth on a blade affects the smoothness of the cut as well as how fast it cuts through material. As a rule of thumb, the more teeth a blade has, the smoother the cut and the slower it is.
Sawsall blades are also classified as either regular blades or breakthrough blades. Breakthrough blades have more teeth and less space between them which makes them capable of cutting through thicker materials. Regular blades, on the other hand, provide a smoother finish but are not good for thick metals and other tough materials.
What is the Best Sawzall Blade Brand?
When it comes to buying sawzall blades there are several popular brands that you might run into. While there are others that are good quality, these are the most well-known ones and usually the easiest to find:
CMT is one of the top brands when it comes to sawzall blades and other metal cutting tools. They are designed for both industrial and professional use and are very durable. They are a good buy for professionals who will be using their tools regularly.
Bosch is another popular brand and they make both regular and breakthrough blades in a wide range of sizes and thicknesses. They are top quality blades that are very durable and made to last. They are a little more expensive than other brands but are well worth the money.
Makita has been making excellent sawzall blades for years as well as all kinds of other power tools. Their breakthrough blades are some of the best on the market and their prices are fair.
Do I Need a Special Breakthrough Blade?
Breakthrough sawzall blades are made with thicker metal and have more teeth than regular blades. This enables them to cut through much thicker materials with a smoother finish than regular blades. Most of the time, you won’t even need to change the blade or sharpen it until it is so worn down that it can no longer make a smooth cut. If you work on projects that involve cutting through metals and other thick materials then you should definitely consider buying a breakthrough blade. They are much more durable and will save you time and effort in the long run.
How Do I Choose the Right Blade for My Needs?
To choose the right blade for your needs, you should consider several different factors. These include:
The material you will be cutting
Whether or not you need a breakthrough blade
The size of the blade teeth
Whether or not you want a regular blade of breakthrough blade
What is the purpose of the sawzall blade?
The material that you will be cutting is one of the main factors because different materials require different sawzall blades. While there are some blades that can handle several different kinds of materials there are others that do a much better job with just one or two. For example, a general purpose blade can handle wood, plastic and soft metals but won’t be good for concrete or stone. There are also blades that are much better for wood than metal.
Along with the type of material you will be working with, you also need to consider if you need a breakthrough blade or not. As we’ve already discussed, breakthrough blades are designed for tougher materials and can cut through many different kinds of materials, including brick and concrete. They can also save you a lot of time when cutting through thick materials because they have more teeth and a thicker metal blade. Regular blades, on the other hand, are designed more for softer and easier to cut materials such as wood and soft metals. While you can cut through harder materials with them, it just takes much longer.
The size of the blade teeth will also play a factor in what you need because different materials require different sized teeth to make a cleaner cut. Some blades have large teeth for wood and plastic while others have very small teeth for thin metal sheeting.
