Milwaukee Random Orbital Sander Replacement Pad: A Comprehensive Guide
When it comes to woodworking, sanding is a crucial step that ensures a smooth, professional finish. Milwaukee's random orbital sanders are renowned for their performance and durability, but even the best tools require maintenance and replacement parts. One of the most common components that need replacing is the sanding pad. This guide will walk you through the process of selecting and replacing the pad on your Milwaukee random orbital sander.
Understanding Your Milwaukee Random Orbital Sander
Before we dive into the replacement process, let's briefly discuss Milwaukee's random orbital sanders. These tools feature a unique sanding motion that combines random orbit action with a circular motion. This dual action helps eliminate swirl marks and provides a smoother finish. The sanding pad, also known as the backing pad, is the component that holds the sandpaper and facilitates this motion.
Signs It's Time to Replace Your Sanding Pad
- Worn Out Sandpaper: If you're finding it difficult to get a smooth finish despite using new sandpaper, it might be due to a worn-out pad.
- Vibrations: Excessive vibrations can indicate that the pad is no longer securely attached to the tool.
- Noise: A loose or damaged pad can cause unusual noises when the sander is in use.
Choosing the Right Replacement Pad
Milwaukee offers a range of sanding pads designed to fit specific models of their random orbital sanders. When selecting a replacement pad, ensure you choose the one compatible with your tool. Here's a quick guide to help you:
| Milwaukee Random Orbital Sander Model | Recommended Pad Size |
|---|---|
| 2648-20 M18 | 5/8" Hook & Loop |
| 2649-20 M18 | 6" Hook & Loop |

Replacing the Sanding Pad: A Step-by-Step Guide
Now that you've selected the right pad, let's proceed with the replacement process. Here's a step-by-step guide:
-
Safety First
Before you begin, ensure the sander is unplugged and the dust collection bag is removed. Also, wear appropriate safety gear, including safety glasses and a dust mask.
Removing the Old Pad
Locate the pad release lever on the bottom of the sander. Pull the lever towards you to release the pad. You should now be able to slide the old pad off the tool.

Installing the New Pad
Align the new pad with the tool's spindle and slide it onto the sander. Ensure the pad is properly seated and the hook and loop surface is facing out.
Securing the New Pad
Push the pad release lever back into place to secure the new pad. You should hear a click, indicating that the pad is locked into position.
Proper Care and Maintenance of Your Sanding Pad
Regular maintenance can extend the life of your sanding pad. Here are some tips to keep your pad in good condition:
- Regular Cleaning: Remove dust and debris from the pad after each use to prevent clogging and ensure optimal performance.
- Store Properly: When not in use, store your sander with the pad removed to prevent warping or damage from prolonged pressure.
- Use the Right Sandpaper: Always use sandpaper that's compatible with your pad to avoid damaging the hook and loop surface.
Replacing the sanding pad on your Milwaukee random orbital sander is a straightforward process that can help you maintain the tool's performance and extend its lifespan. By following this guide and practicing proper care and maintenance, you can ensure that your sander continues to deliver smooth, professional results for years to come.
