How to Put a Blade in a Reciprocating Saw

Are you someone who works on important jobs that involve cutting through tough objects such as metal or hardwood?

Reciprocating saws are your best bet. These saws move back and forth instead of moving in a circular motion and are pointed to a certain extent. This means that they can get into tight corners (not possible with other saws).

Different kinds of blades can be attached to a reciprocating saw, depending on the material you are working with. The added back-and-forth function allows you to cut through objects in much less time using lesser force and energy.

Make sure you learn how to use a reciprocating saw before you attempt to change its blade. Following instructions will ensure your machine lasts much longer than it would if you did not take proper care of it.

Using a Reciprocating Saw.

Before learning how to put a blade in a reciprocating saw, we need to understand signs that show that a blade needs changing.

When To Change a Blade In a Reciprocating Saw

Knowing when to change a blade in a saw elongates the machine’s life. You do not want to hack away at objects using a blunt blade. This can put pressure on the machine, causing it to malfunction. It can even harm the teeth of the blade.

1. Partially Sharp Blade

Often, the blade itself has not been affected. However, the teeth are subjected to damage and have thus become blunt with time. Noticing the dullness and getting it fixed can lead to less investment in the future. It also means better craftsmanship and neater cuts.

2. Dull Blade

Does the blade look worn out? Can you see most or all of the teeth bent out of shape? This means that the blade is not sharp anymore and needs to be replaced. Blades often get blunt due to excessive use or simply lying around, gaining rust.

3. Sounds

Knowing what your reciprocating saw sounds like is beneficial for various reasons. One of these is that the moment your saw starts to work overtime, you will learn something is wrong. This is the last resort, a final warning for you to replace your blade.
