Changing a Cutting Wheel on Dewalt Angle Grinder

Only 4 Steps Needed to Change the Cutting Wheel

This step-by-step guide will help you understand the cutting wheel replacement without running into loading, flange, or spindle lock issues.

You’ll find out the easiest way to replace an angle grinder wheel, how to remove your old blade, and secure nuts without failing.

After understanding these factors, you’ll be able to change an old cutting wheel to a new one, saving your efforts and time.

Step 1: Unplug the Grinder from the Power Source

Safety is an integral part of the machine’s operation that you should not take for granted. You need to put items like goggles, leather gloves, earplugs, and necessary protective items in place before commencing operations.

Before you consider changing or replacing cutting wheels in the machine, your first task is disconnecting the tool from power.

If you’re using a corded angle grinder, unplug from the power source to prevent unexpected accidents. But if you have a cordless machine, the handling and mode of operations are different.

Your first task with a cordless device is removing the battery. When you remove the battery from the device, it becomes lighter and easy to place a cutting wheel for efficient performance.

Tap and hold the spindle lock on the machine’s stem. You will find this lock between the wheel protector and the body. It’s time to swing your hands into action.

Use your hand to rotate the wheel until it falls into position for optimal performance.

Step 2: Unscrew Old Disc

After getting your protective gear in place and unplugging the machine from the power source, it’s time to remove your old disc from the machine.

When you purchase a new grinder, it usually comes with two wrenches to serve various purposes.

The first one looks like a regular wrench, while the other looks similar to a long fork. Both wrenches are ideal tools for removing cutting wheels from the machine and are integral in this process.

If you’re wondering how to use a wrench to remove cutting wheels from Dewalt angle grinders, firstly mark out the hole between the disk and motor.

After marking the holes, it’s time to insert the prongs before using the wrench spanner to bolt the bottom of the cutting wheel. Many people make mistakes in this section by fixing the blade the wrong way.

If your disc arrow faces one direction, the pronged spanner should face the opposite. It will be best to turn the pronged spanner in the other direction of the blade arrow.

Remember that you need to bold the nut until you can see the disc on display from the grinder. Secure the wheel and ensure it spins anticlockwise with the wrench before moving to the next step.

If the original wrench is missing, consider using the regular one.

Step 3: Remove the Disc

Now that you can loosen necessary bolds, it’s time to focus on removing the old cutting wheel before replacing it with a new one.

If you want to drive the bolt efficiently, make sure the vice grip holds the disk bolt tightly before starting operations.

The vice grip keeps the cutting wheel in position and prevents unnecessary spinning that may derail your project or cause injuries.

The concepts involved in putting a cutting wheel in a Dewalt grinder seem tedious for beginners but straightforward for experts. It’s time to call your screwdriver into action.

Use the tool to unscrew the bolts between the disc and motor before turning it in the opposite direction.

The process should loosen the old disk, and you can begin the extraction process. If the case is different and the disc fails to loosen, bring your hammer into the fold.

Forcefully use it to turn the screwdriver before removing the backer plate and old wheel from the machine’s stem.

Step 4: Insert the Cutting Wheel

After completing the first three steps, your old disc should be easy to remove. Remove the cutting wheel with your hands and clean the surface with a rag.

It is advisable to clean the surface to remove debris or dirt that can cause unexpected damage.

Now that you can remove the old disc, it’s time to replace it with a new cutting wheel. Place the wheel into the machine’s drive bolt and ensure you put it correctly for optimal performance.

It would be best if you used the right disc for your Dewalt machine.

If identifying the right disc for your machine becomes a problem, consider talking to the attendant at the store. Use your hand to tighten the disc in the opposite direction, similarly to the old one.

Let the hump rest on the wheel’s top inside the backing plate. Bold the nuts to the stem until it starts to spin. Ensure you hold the spindle lock while using the wrench to bold the nuts.
