Milwaukee Random Orbit Sander

The Milwaukee Random Orbit Sander, model 6125, has been an intriguing addition to my workshop. This corded sander boasts a 10,000 orbits per minute (OPM) speed and a 5/32 inch orbit diameter, which promises efficient material removal and smooth sanding results. Having spent considerable time with this tool, I've come to appreciate its strengths and identify some areas where it falls short.

Performance and Power

One of the standout features of this Milwaukee sander is its power. The 5.5-amp motor provides a robust performance that can handle various sanding tasks with ease. Whether I'm working on softwood or tackling hardwood projects, the sander maintains consistent speed and doesn't bog down under pressure. This is particularly beneficial when using lower grit pads to remove large amounts of material quickly.

The variable speed control is another highlight. It allows me to adjust the speed to suit different tasks, from delicate finishing work to aggressive material removal. The soft start feature is a nice touch, preventing the tool from jerking when it first powers up, which helps in controlling the sander right from the get-go.

Comfort and Usability

Comfort during prolonged use is crucial, and this sander manages to deliver a relatively comfortable experience. The three-position side handle is a thoughtful addition, allowing me to adjust the grip based on the task at hand. The sander is well-balanced, which reduces hand fatigue and makes it easier to control, even during extended periods of use. The low vibration levels are also commendable, as they minimize the strain on my hands and arms.

However, the tool is a bit on the heavier side, weighing in at 5.0 lbs. While this isn't a deal-breaker, it does become noticeable during longer sanding sessions. The cord length, at 8 feet, is adequate for most situations, but I've found myself needing an extension cord for larger workspaces.

Dust Collection

Dust collection is a mixed bag with this sander. While the pressure-sensitive adhesive sanding discs are convenient for quick changes, the dust collection system itself leaves much to be desired. The included filter box does an okay job, but it fills up quickly and can be challenging to clean. The box is difficult to open and close, and dust often gets trapped in the grooves, making it a hassle to maintain.

Connecting the sander to a shop vac significantly improves dust collection efficiency, but the vacuum adapter isn't the best fit. It tends to fall off easily, which disrupts the workflow and can lead to a dusty mess. This is a major drawback, especially for those who prioritize a clean working environment.

Durability and Build Quality

Durability is where this Milwaukee sander struggles. While the tool performs admirably when it's working, I've encountered several issues that raise concerns about its long-term reliability. The hook and loop pad on the sander itself wore out faster than I expected, leading to problems with discs flying off during use. Additionally, the motor experienced issues with overspeeding, which affected the sander's performance and control.

Another significant issue is the internal components. The bearing cap metal wore out prematurely, and the screws stripped out, rendering the tool unusable. This happened despite regular and careful maintenance. Given these problems, it's hard to have confidence in the sander's longevity, especially for professional use or heavy-duty applications.

Noise Level

Noise levels are relatively moderate for a tool of this type. It's not the quietest sander I've used, but it's also not excessively loud. The noise is manageable with proper hearing protection, and it's not a significant factor in my overall assessment of the tool.

Recommendations

Despite its powerful performance and comfortable handling, the Milwaukee Random Orbit Sander, model 6125, has several shortcomings that make it hard to recommend wholeheartedly. The inconsistent dust collection system, durability issues, and occasional performance glitches are significant drawbacks.

For hobbyists or those who need a sander for occasional use, this tool might still be a worthwhile investment due to its powerful motor and adjustable speed settings. However, for professionals or those who require a reliable sander for heavy-duty or frequent use, the durability concerns and dust collection issues make it a less appealing choice.

In conclusion, the Milwaukee Random Orbit Sander has its merits but falls short in critical areas that affect long-term usability and reliability. If Milwaukee addresses these issues in future iterations, this sander has the potential to be a top contender in its category. For now, I would recommend exploring other options, especially for those needing a sander that can withstand rigorous and frequent use.
