While I was looking for a Random Orbit sander, I considered Bosch ROS20VSC vs Dewalt DWE6423K. Having used both brands for years. I combined that with information gathered through experience and research to add value to the debate. Features worth comparing include speed, cost, dust collection system, weight, design, and weight. Matching these features with your expectations will point to your top pick.
Overview of the ROS20VSC
It is a Random Orbital sander that makes smooth wood surfaces. You will not have swirl marks on your surface due to the pad dampening system removing marks on either flat or contoured surfaces. The hook and loop disc attachment system keeps the pad in place. They have durable material. It performs the duty of the Velcro adhesion material.
The sander has a speed variance of 7,500 OPM up to 12,000OPM. The 2.5 Amp motor allows the speed to change depending on the material it is working on. The sander has a microfilter dust canister that traps dust particles. The package includes a sanding pad, case, dampening ring, sanding disc, dust canister, and a vacuum adapter. The installation process is easy.
The eight holes are inside the ring of the pad. There is a space between the sanding pad and the disc that has to be closed. The ROS20VSC runs smoothly, and that makes it a low vibration tool. The dampening brake system also makes it smooth. The vibration rate is controllable. There are no extra tools you have to look for. All the accessories you need come inside the package.
- Smooth finish
- Easy disc attachment
- Speed variance
- Dust collection feature
- Extended palm
- The lid bin is difficult to close
- The dust filter could have been more efficient
Key Features of the ROS20VSC
The ROS20VSC comes with a variable speed control system. That means you have the power to adjust your speed and set your preferred speed as you cut through materials. The tool runs at 7,500 OPM up to 12,000OPM. Low speed is ideal for simple areas and high speeds for rough materials.
The sanding disc is easy to install. You need to match its holes with the eight holes inside the ring pad and press. Little effort is required to close the space between the pad and the disc.
The pad dampening system eliminates swirl marks on flat and contoured surfaces. The disc attachment is easy to run. It uses a Hook and Loop disc system that sticks sanding pads to the sander. It is like a Velcro adhesion material.
Dust collection system
The sander features a microfilter dust canister that traps dust and other particles that are as small as ½ micron in diameter. The canister lasts longer since it is of quality materials. The canister shows dust level. When you are working on dust-free tasks, you can easily detach the canister. When you want to empty the dust container, you twist it. The same applies when you want to attach it.
Overview of the Dewalt DWE6423k
The DWE6423k has a 3 amp motor that spins from 8,000 to 12,000 OPM. The height draws you closer to the machine no matter how tall or short you are. That will relieve you from the strain that comes with reaching out to sanding machines. The counterweight design is noticeable at the top of the works as a shock absorber.
You do not feel vibrations and that improves the comfort of the machine. The rubber over-mold takes care of tough areas of the sanding machine. The dust collection system keeps you safe from sawdust and makes your tool last longer. It comes with a dust bag handled using one hand. The bag does not require you to empty it in a short period. The dust port fits directly to the DWV010 or the DWV012 dust collectors. The sander weighs up to 4 pounds.
The package includes the sander, dust bag, owner’s card, and a carrying bag. It is ideal for DIY enthusiasts since it is easy to use and connects to the vacuum. The sander is smooth and easy to maneuver. It is not difficult to use on tricky parts of an item. You need to make sure that you have lined up the holes at the bottom perfectly so that changing the sanding pads will not be difficult.
- Low vibration
- Light and ergonomic
- High quality
- An adaptor for the shop vac is required
- The dust bag could be bigger
Key features of the Dewalt DWE6423k
Dust collection system
The improved dust-sealed switch protects you from dust ingestion that makes your machine last longer. The dust collection system keeps your workshop dust-free. The dust bag is a one-handed locking bag that is easy to use. The dust port fits perfectly into the DWV0110 or DWV012. You can add an adapter if you wish to use a shop vac. You can have your machine connected to a universal Quick Connector DWV9000.
Safety features are there to ensure that you have a safe workplace. Rubberized handles prevent your hands from slipping. It protects your tool from damage on hard surfaces and the ergonomic design protects you from electrical shock. The dust-sealed switch makes you safe from just sawing. The vacuum locking system allows you to have a secure dust bag attachment.
The handle makes the tool handy when operating. The Dewalt sander has a large palm grip just above the sander. The handles are rubberized, and that is very comfortable to hold. The handles give better sanding in tricky areas. Your hands are safe on harsh surfaces.
Powerful motor and Speed
The 3 amp motor produces spins between 8,000 and 12,000 OPM. The orbit is electric-powered, and it makes vibrations. However, you do not feel the vibrations due to the counterweight design that absorbs the vibrations. The motor has an air vent for high air circulation that controls overheating. The variable speed control system makes it accurate. The polishing process is made smooth.
- Both sanders have variance in speed.
- They both have a maximum speed of 12,000OPM.
- Both sander tools have low vibration.

If you have a tight budget, the Bosch is the product I would recommend. For a sander with a lower speed limit, I recommend the Bosch ROS20VSC. If you prefer a micro-filter canister to a dust bag, the Bosh ROS20VSC sander is the ideal product. Yet, both products have low noise, speed variance, and powerful motors. I am sure you have found your best pick between the two.
