Buying Guide

At first glance, it may seem like all there is to reciprocating saws is a handle, a trigger, and a blade. But as you’re probably already aware, there are several different types and brands, each with its own pros and cons. The features you should look for in a reciprocating saw will depend on what you plan on using it for, but for most people, a lightweight saw with a blade that’s around 10-inches long will be the best option.

Reciprocating saws are a fairly common tool that can be found in most toolboxes. Whether they are being used in construction or remodeling, they are a useful tool to have on hand. One of the main parts of the reciprocating saw is the blade, which is a very important component of the tool. Different blades can be used for specific jobs, so knowing the different types of blades is very important.

i. High Carbon Steel Blade

Whether you are cutting through the base of a steel support beam, or a giant tree stump, a reciprocating saw is a great tool to have on hand if you don’t have access to power tools. However, picking out the right blade is the most important step in getting the job done right. Never use a dull blade, or you will be forced to apply so much pressure that you risk breaking the blade or the blade guard.

ii. High-Speed Steel

People who work with a reciprocating saw will find that the blades are more important than the saw itself. Some blades are made of high carbon steel, which is too hard to bend and too brittle to hold its edge. (It’s like trying to cut butter with a hammer!) Other blades are made of high-speed steel (HSS), which is much more flexible and much harder than carbon steel. HSS blades feature diamond or carbide tips that stay sharper longer.

iii. Bi-Metal

A reciprocating saw is a powerful tool that makes it easy to cut through hard surfaces with maximum efficiency. However, it requires the right blade to deliver quality results. A bi-metal blade is a popular choice, as it gives you a fast start and an even finish. You can use it to cut through wood, metal, or any other material for that matter. The blade is made of a combination of two types of metal to offer versatility, durability, and strength. The metal is usually a combination of high carbon steel, which is tough and durable, and alloy steel, which is flexible and helps the blade reach its maximum potential.

iv. Diamond

The diamond blade is a reciprocating saw blade used to cut through hard materials such as stone, tile, and steel. It is very efficient and can cut through materials quickly and effectively, making it a popular choice for a variety of applications. There are many different types of diamond blades on the market. They can range from four inches to nine inches in length. The depth of the diamond also differs from one blade to the next.
“This is an excellent tool to have if you are a carpenter, construction worker, or simply a handyman. This blade is durable because the teeth of the blade are made of carbide. It is also lightweight, flexible, and easy to use.

You’ll want to make sure you have the right size blade for your reciprocating saw, as using a too small or too large one can cause the saw to run poorly or not at all. Generally speaking, the length of a blade usually determines the size of the hole it can bore, while the width is used to cut through the tubing and other materials. For instance, using a blade with a size of 3-1/4″ wide and a size of 2-1/2″ long will work well for many jobs.


The ideal length of the blade for reciprocating saw depends on the application, and as is the case with most tools, the bigger the blade the better. An 8-inch blade is a good all-around length for home improvement jobs, but if you need to cut through masonry, pipes, or other hard materials, you might need a blade as much as 10 inches long.
The most common reciprocating saw blade width is 7-1/8 inches. These blades are available in several different back designs, which determine the thickness of the blade and the amount of the blade that protrudes beyond the saw’s body.

In the case of a reciprocating saw, one of the most important tools for cutting through wood, metal, concrete, and even drywall is the reciprocating saw blade.

Reciprocating saw blades come in all shapes and sizes, and each size and shape has its own special use. You may be surprised to learn that the shape of a saw blade is not strictly dependent on its function. Many blades that are designed for high-speed woodcutting, for example, may look different than those designed


What do you mean by the speed of the blade?

A reciprocating saw is a common power tool used for cutting wood, metal, plastic, and other common materials. The saw blade is attached to a high-speed motor that spins, and it is lowered onto the material to be cut, creating a sawing action. The speed of the blade can be adjusted, and it is usually adjustable from between 0 to 1,500 strokes per minute.

What determines the amount of control when you are using a reciprocating saw?

The speed and power of the motor determine the amount of control you have when cutting with the saw, and is one of the most important features that you’ll want to consider when choosing a reciprocating saw.

What is the ideal size of the blade?

According to experts, using a blade with a size of 3-1/4″ wide and a size of 2-1/2″ long will work well for many jobs.

Why most carpenters prefer HSS blades?

Other blades are made of high-speed steel (HSS), which is much more flexible and much harder than carbon steel.

What is the ideal width of the reciprocating saw blade?

The most common reciprocating saw blade width is 7-1/8 inches.
