One To Avoid

Clarke CAT160 Professional 6" Dual Action Random Orbital Palm Sander

We've also put the Clarke CAT160 Professional 6" Dual Action Random Orbital Palm Sander to the test, and while it has some promising features, it ultimately falls short in key areas.

At first glance, the sander appears well-built with its rugged construction and adjustable speed control, offering durability and some level of versatility. The random orbit motion does help reduce swirl marks, and the 150mm hook and loop pad allow for quick sanding disc changes.

However, these positives are quickly overshadowed by its flaws. One of the biggest issues is air consumption. This sander requires 14.8 cfm at load, which means you’ll need a powerful air compressor to keep it running properly.

Many standard compressors will struggle to provide the necessary airflow, making it frustrating to use. Additionally, it is extremely noisy, and the vibration levels could be better controlled for improved handling.

The dust extraction system is another letdown. While it comes with a hose and bag, its effectiveness depends on how well it connects to your system, and it often falls short.

Overall, while the Clarke CAT160 may seem like a solid choice, the excessive air consumption, loud operation, and subpar dust collection make it one to avoid unless you’re willing to work around its many drawbacks.

How We Tested and Chose the Best Orbital Sanders

Finding the best orbital sander isn’t just about turning it on and sanding a piece of wood. We put each model through rigorous hands-on testing to evaluate its performance, durability, and usability across different surfaces and applications. Here’s how we did it.

Performance Testing

To assess how well each sander smooths surfaces, we tested them on a variety of materials. Softwood like pine and hardwood like oak and maple were used to measure efficiency and evenness. We checked how effectively the sander removed old paint and varnish without excessive clogging.

Plaster and drywall were sanded to determine how well each model prepped surfaces for painting. We also tested flexibility by sanding curved edges, corners, and rounded furniture pieces to see how well they handled uneven surfaces.

Power and Speed Evaluation

Power output plays a crucial role in sanding efficiency. For corded models, we measured motor wattage, while cordless units were tested for voltage. Each sander’s minimum and maximum orbit per minute (OPM) settings were evaluated to see how well they adjusted to different materials.

We ran each unit for extended periods to assess sustained performance, ensuring there was no overheating or power drop-off after 30 minutes of continuous use.

Ergonomics and User Comfort

A sander should be easy to control and comfortable during prolonged use. We evaluated grip comfort by checking how well the soft-grip handle reduced hand fatigue over time. Weight and balance were tested to determine ease of use, especially on vertical and overhead surfaces.

Vibration levels were analysed both subjectively and with a vibration meter to assess their impact on control and comfort. Noise levels were measured in decibels to compare which models operated more quietly.

Dust Collection Efficiency

Good dust collection is essential for maintaining a clean workspace and reducing airborne particles. We tested the efficiency of built-in dust bags, noting how quickly they filled up and how much dust they captured.

Each sander was attached to a shop vacuum to determine compatibility and effectiveness in reducing debris. MDF and drywall were used to measure how well each model controlled fine dust, ensuring that workspaces remained as clean as possible.

Durability and Build Quality

To evaluate long-term reliability, we examined the materials used in each sander. Plastic and metal components were compared for strength and wear resistance. We ran each sander at high speeds for extended periods to check for overheating and potential motor strain.

The longevity of sanding discs was also measured by testing how quickly different grit papers wore down across various surfaces.

Battery Life (Cordless Models Only)

For cordless sanders, battery efficiency is a major consideration. Each battery was fully charged and tested at maximum speed to determine runtime.

We measured how long it took for the battery to recharge and assessed whether the model was compatible with other tools in the same battery ecosystem, such as Milwaukee M18, DeWalt XR, or Makita LXT.

Value for Money

A sander’s price should reflect its performance, durability, and features. We compared the cost of each model against competitors in the same price range to determine whether it provided good value.

Included accessories, such as extra sanding discs, dust bags, or storage cases, were taken into account. Finally, warranty length and brand reputation were considered, with preference given to models backed by at least a two-year warranty and positive customer reviews.

Frequently Asked Questions

Is an Orbital Sander Worth It?

An orbital sander is worth it for anyone who frequently works with wood, drywall, or painted surfaces. It provides a smooth and even finish while reducing manual effort.

With its random orbit motion, it minimises swirl marks and delivers professional-quality results, making it an essential tool for both DIYers and professionals.

Should an Orbital Sander Be Fast or Slow?

An orbital sander should be adjusted based on the material and the desired finish. A slower speed is ideal for delicate surfaces and fine finishing, while a higher speed works best for removing material quickly. Using variable speed control ensures optimal performance depending on the task at hand.

What Grit Is Best for an Orbital Sander?

The best grit for an orbital sander depends on the project. Coarse grits (40-80) are ideal for removing paint or rough shaping, medium grits (100-150) work well for general sanding, and fine grits (180-220 and above) are best for finishing and preparing surfaces for staining or painting.

Should You Push Down on an Orbital Sander?

You should not push down on an orbital sander, as applying excessive pressure can reduce efficiency, cause uneven sanding, and wear out the motor faster. Instead, allow the sander’s weight and motion to do the work, keeping steady, light contact with the surface for the best results.

Is a Corded or Cordless Orbital Sander Better?

A corded orbital sander is better for continuous power and high-performance sanding, making it ideal for extended use. A cordless orbital sander offers greater mobility and convenience, making it perfect for on-site work or areas without power access.

Choosing between the two depends on the project's needs and work environment.

What Are the 5 Most Common Mistakes People Make With a Random Orbital Sander?

The five most common mistakes people make with a random orbital electric sander include:

1. Using the wrong grit: Selecting a grit that is too coarse or too fine can impact the quality of the finish.
2. Applying too much pressure: Pressing down too hard can cause uneven sanding, excessive wear on the motor, and surface damage.
3. Not changing the sanding disc frequently enough: Worn-out discs reduce efficiency and can leave inconsistent results.
4. Skipping dust collection measures: Failing to use a dust bag or vacuum attachment can lead to a messy workspace and airborne particles affecting health.
5. Sanding too aggressively in one spot: Holding the sander in one place for too long can create swirl marks and uneven surfaces.
