Last updated on December 1st, 2022 at 10:05 am

When deciding between a Bosch ROS20VSC vs ROS20VSK sander, you need to look at the performance and features of each. The ergonomic design is also essential. However, these two devices have more similarities than differences. The differences include the carrying cases and the price. We will evaluate more differences in this article to help you.

Overview of the Bosch ROS20VSC

Bosch ROS20VSC 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 are made of durable material that makes them last longer. It performs the duty of the Velcro adhesion material. 

The sander has a speed variance of 7,500 OPM up to 12,000 OPM. 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. Installing discs requires matching eight holes with the holes of the disc and press. 

The eight holes are inside the ring of the pad. There is a space between the sanding pad and the disc to get rid of. The Bosch 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 additional tools you have to look for. All the accessories you need come inside the package.

Pros

• Smooth finish
• Easy disc attachment
• Speed variance
• Dust collection feature
• Extended palm.

Cons 

• The lid bin is difficult to close
• The dust filter could have been more efficient.

Key Features of the Bosch ROS20VSC 

Speed

The Bosch ROS20VSC comes with a variable speed control system. You can adjust and set your preferred speed as you cut through materials. The tool runs at 7,500 OPM up to 12,000 OPM. Low speed is ideal for simple areas, and high speed for rough materials. 

Sanding disc and pad

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. The sanding disc is easy to install. You must 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.

Dust collection system

The sander features a microfilter dust canister that traps dust and particles as small as ½ micron in diameter. The canister shows the dust level. The canister lasts longer since it is made of quality materials. When 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 Bosch ROS20VSK

Bosch ROS20VSK is also a Random orbit sander with a 2.5 Amp motor that runs from 7,500 to 12,000 OPM. As much as it runs faster, it remains a low-vibration tool. It has an integral pad-dampening system that prevents swirl marks on multiple surfaces. The ergonomic design makes the machine’s top part give the user soft gripping. The top part is also wider. 

That brings comfort to the hands of the user. The microfilter dust canister with the tool filters all the dust particles collecting dust into a pod. The dust canister is made of long-lasting materials. It is protected from dust. The tool is compatible with a standard 5-inch hook-and-loop. The switch button is significant, thereby leaving no room for mistakes. 

The hard carrying case ensures that it will not be damaged if the tool falls on the ground. When attaching sanding pads, less effort is needed. You only need to match up holes as you stick the pads to the sander. The package includes a sanding pad, vacuum adapter, hard carrying case, sanding disc, dampening ring and dust canister. The build quality is impressive. 

Pros 

• Speed variance
• Micro-filter system
• Easy disc attachment
• Smooth finish
• Impressive build quality.

Cons

• The dust canister has clogging that needs regular cleaning.
• The converter does not stay on the sander.

Key features of the Bosch ROS20VSK

Speed

The machine has speed variance that gives you control over your sander machine. You have to control your speed depending on the material you are working on. Speed variance is a feature on a heavy-duty sander machine like the Bosch ROS20VSK. It makes sanding accurate on multiple types of materials. Delicate surfaces attract low speed, and on rough surfaces, vice-versa. The no-load speed ranges from 7,500 to 12,000 OPM. 

Dust collection system

This sander has a dust collector that comes as a filtering paper. The paper filters almost all the particles that come from the machine. That is more effective than the bag. The canister needs regular cleaning to avoid clogging. The filter has to be clean for excellent performance.

Disc attachment

The tool comes with a hook and loop disc attachment. That is quite impressive in securing a disc. Chances are low that the disc will move out of place. The sander comes with 35,000 hooks with a tight grip on the disc while running the machine. The dust canister lasts longer; when emptying it, zero dust escapes from the bag to the sander machine.

Bosch ROS20VSC and Bosch ROS20VSK Similarities

• Both are Random orbital sanders.
• The products use available 5-inch discs.
• Both products withstand the pressure of sanding on flat and contour surfaces.
• Both sanders use the hook and look surface.
• They both have the same speed, which ranges from 7,500 to 12,000 OPM. 

Differences between Bosch ROS20VSC and Bosch ROS20VSK

The Bosch ROS20VSC comes with a soft carrying bag, whereas the Bosch ROS20VSK comes with a hard case. The Bosch ROS20VSC carrying bag is of soft linen material inside and has a zipper. The Bosch ROS20VSK case has a latch to keep it closed.

Cost 

Both products are in the same price range as they are below 100. However, if you want to save a few bucks, the Bosch ROS20VSC is better than the Bosch ROS20VSK.

Verdict

When comparing the Bosch ROS20VSC and Bosch ROS20VSK, you need to consider the price and the type of case a device comes with. There is not much difference between the two. For a less expensive sander, I recommend the Bosch ROS20VSC. If you prefer a hard case to a soft carrying case, the Bosch ROS20VSK hand sander would be ideal.
