How to Install a Sawzall Blade
If you’re a DIY enthusiast or a professional contractor, you’ve likely encountered the need to use a Sawzall at some point. This powerful reciprocating saw is a versatile tool that can handle a wide range of cutting tasks. However, before you can start using your Sawzall, you’ll need to install a blade. In this article, we’ll provide step-by-step instructions on how to install a Sawzall blade in an old Craftsman model. Whether you’re new to using a Sawzall or just need a refresher, this guide will have you up and running in no time.
To begin, you’ll need to gather a few tools. You’ll need a hex key or Allen wrench that fits the bolt on the Sawzall’s blade clamp. In most cases, this will be a 3/16-inch hex key. You’ll also need a pair of safety glasses to protect your eyes from flying debris. Once you have your tools, you can start the installation process. First, make sure that the Sawzall is unplugged and the blade is not installed. Then, locate the blade clamp on the front of the Sawzall. The blade clamp is a U-shaped bracket that holds the blade in place. On old Craftsman Sawzalls, the blade clamp is typically held in place by a bolt with a hex head.
Next, insert the hex key into the bolt and turn it counterclockwise to loosen the bolt. Once the bolt is loose, you can remove the blade clamp by pulling it forward. With the blade clamp removed, you can now insert the Sawzall blade. Make sure that the blade is facing the correct direction. The teeth of the blade should be facing away from the motor. Once the blade is in place, you can reattach the blade clamp. To do this, simply slide the blade clamp back onto the Sawzall and tighten the bolt using the hex key. Finally, double-check that the blade is securely fastened before plugging in the Sawzall and starting to use it.
Select the Correct Blade for the Job
1. Metal Cutting Blades: These blades are made of high-speed steel (HSS) or bi-metal and are designed for cutting through metal, such as conduit, pipe, and sheet metal. They feature a fine tooth count (18-24 teeth per inch) and a hardened cutting edge. Choose a blade with a tooth count that matches the thickness of the metal you’ll be cutting.
2. Wood Cutting Blades: These blades are made of high-carbon steel or tungsten carbide and are designed for cutting through wood and other soft materials. They feature a larger tooth count (10-16 teeth per inch) and a sharper cutting edge. Choose a blade with a tooth count that matches the thickness of the wood you’ll be cutting.
3. Demolition Blades: These blades are made of hardened steel and are designed for heavy-duty demolition work, such as cutting through drywall, plaster, and wood with nails. They feature a coarse tooth count (6-10 teeth per inch) and a thick, reinforced body. Choose the longest blade that will fit your saw and can reach the area you need to cut.
4. Pruning Blades: These blades are made of hardened steel or carbide-tipped and are designed for cutting small branches, limbs, and roots. They feature a narrow blade profile and a sharp, pointed tip. Choose a blade with a tooth count that matches the diameter of the branches you’ll be cutting.
