coarser grade of abrasive. Move the sander in long sweeping strokes, parallel to the grain using some lateral motion to overlap the strokes by as much as 75%. The random orbit action allows cross-grain sanding, but be careful not to tilt the sander near edges, or undesirable rounding may result.

SANDING SEQUENCE

If the surface is rough, begin with coarser grits and then complete the surfacing with medium and fine abrasives. Because the random orbit action is so effective, it is often possible to begin sanding with a medium grit disc and go directly to fine finishing. To avoid uneven results, do not skip more than one grit size when going from coarser to finer, and do not sand in one area for too long.

REMOVAL OF SANDER

To help prevent swirl marks when the job is completed, gently lift the tool from the work surface, then switch the tool off.

POLISHING

For most polishing, the soft backing pad will give the best results. The random orbit sander may be fitted with an optional foam buffing pad or polishing bonnet to polish or remove scratches from painted or finished surfaces, plastics, and even glass. The tool is operated in much the same way as when

sanding, but the following points should be observed;

Apply the compound to the surface, and use the sponge applicator pad with light pressure and a circular motion to remove scratches and restore weathered finishes. Use only as much compound as necessary, and clean the sponge frequently during use.

When initial polishing is completed, wipe away any excess compound with a soft towel, and then polish the surface to its final finish with the polishing bonnet. Use smooth overlapping strokes for best results.

It is important to note that the orbit speed of the random orbit sander is not the same as the RPM of a standard right-angle polisher. The random orbit action is much like a powerful hand polishing action, and therefore does not have the high speeds at the edge of the pad which can burn the work surface. For this reason, it is possible to select a higher OPM for the random orbit sander than the recommended RPM for a standard polisher. Practice on a hidden area or test surface until you have determined the tool is suitable for your polishing application.

Clean the buffing pad and polishing bonnet with mild detergents and warm water. DO NOT use solvents.

Bosch Power Tools has built a formidable reputation for producing high-quality tools that cater to both professionals and DIY enthusiasts. Among their stellar lineup are the ROS10 and ROS20VS random orbit sanders, which showcase the company’s commitment to innovation, durability, and user comfort.

The Bosch ROS10 is designed for smooth and efficient sanding tasks. One of its notable features is the Microfilter System, which helps trap dust particles as small as half a micron. This ensures a cleaner workspace and contributes to better visibility while sanding. Moreover, the ROS10 offers a 2.5-amp motor that provides a robust performance with a no-load speed of up to 12,000 orbits per minute. This makes it ideal for various applications, from removing old paint to preparing surfaces for finishing.

An ergonomic design is a key characteristic of the ROS10, featuring a soft-grip top and body that enhance comfort during extended use. The tool’s lightweight build further minimizes user fatigue, allowing for longer sanding sessions with reduced strain. The hook-and-loop attachment system for sandpaper makes changing sandpaper discs swift and hassle-free, promoting increased productivity.

On the other hand, the Bosch ROS20VS brings versatile features that make it suitable for both detailed tasks and broader sanding jobs. It boasts an integrated dust collection system that actively collects dust through a built-in vacuum port, ensuring a clean and efficient work environment. Equipped with a variable speed control, the ROS20VS allows users to customize the speed depending on the material and the type of project, making it adaptable for a wide range of tasks.

With its 2.5-amp motor and premium construction, the ROS20VS also delivers exceptional power and durability. This sander includes an ergonomic design that combines comfort with control, featuring a soft-grip handle and well-balanced structure. Additionally, the user-friendly design of the dust canister makes it easy to empty and clean after use.

In summary, both the Bosch ROS10 and ROS20VS random orbit sanders are engineered to offer remarkable performance, effective dust management, and superb handling. Their advancing technologies and user-centric features make them indispensable tools in any woodworking or remodeling project. Whether you’re a seasoned professional or a dedicated DIYer, these sanders promise to deliver outstanding results every time. Make a choice between these two tools based on your specific needs, and elevate your sanding experience to new heights.
