How to use Dremel Sanding Discs

How to use sanding discs on a dremel

Sanding may transform a mediocre project into a masterpiece. Wood that has just come out of the mill may be rough or have dents and other markings. Sanding the surface of the wood helps to smooth it out. It can also bring out the natural beauty of the wood grain. Sanding tools can also prevent rust from metal and polish fiberglass. 

Finally, sanding the surface prepares it for painting; it ensures that the paint (or varnish) goes on smoothly and looks its best. Sanding is one of the most crucial phases in defining a project’s final polish and quality.

The sanding surface will determine the type of sanding tool you employ. Nothing beats high-speed stationary sanding equipment for large surfaces. You can also use sandpaper alone, sandpaper with a sanding block, an orbital sander, or a rotary tool like the Dremel Multi-Tool instead of this equipment.

When only light sanding is necessary, or the surface is relatively soft, hand sanding techniques are the ideal option. Many woodworkers use orbital sanders for flat surfaces, while the Dremel Multi-Tool is suitable for detailed work and hard-to-reach regions. Decorative chair legs, for example, would be challenging to smooth with an orbital tool’s flat surface.

Here is how you sand using Dremel sanding discs

Step 1: Put on your protective gear. You should wear your gloves and goggles before operating the disc sander.

Set up the Disc Sander in

Step 2. Place the disc sander in a less-trafficked location.

Step 3: Gather your materials.

Step 4.

Turn on the Disc Sander in

Step 6:

Make any necessary adjustments.

Dremel sanding discs are commonly helpful for smoothing and shaping wood and removing paint. It is ideal for sanding soft materials like wood and fiberglass to a (smooth) flat edge. The grit of Dremel sanding discs is more refined than that of Dremel sanding bands. It’s also suitable for removing rust.

The lower the grit, the greater the amount of material removed. These discs are flexible enough to handle any curves on the project and are best suitable with the Dremel tool facing the work item. For best results, we recommend focusing on the disc’s center. 

These disks are helpful to sand / smooth softer materials such as hardwood, softwood, plastic, fiberglass, and aluminum, as well as remove rust from metals such as steel. Rubber surfaces can also be shaped. Sanding discs wear out over time, and you must replace them by removing the mandrel.

Rotary tools from Dremel are among the most efficient hand power tools available. Using a Dremel, you can grind, cut, carve, polish, route, engrave, and sand. A special Dremel mandrel is required to sand using a sanding disc. Sanding discs come in various grits, including 180, 220, and 240 grit. The tools needed to mount the mandrel to a Dremel tool come with purchasing the product.

1st Step

Remove the power cord from your Dremel rotary tool. Using the collet wrench, loosen the collet and, if necessary, remove the accessory from the collet.

2nd Step

Using the wrench, tighten a No. 402 Dremel mandrel into the collet. Remove the tip screw from the mandrel by loosening it.

Step 3: Thread the mandrel tip screw through the sanding disc’s center hole. Screw the screw into the mandrel and tighten it.

Step 4 

Connect the Dremel rotary tool into such an electrical outlet and set the variable speed choice switch for hardwood and softwood materials to “12” to “17” and for laminates and plastic products to “5” to “8.”

Sanding discs come in two categories. The first is sanding discs that are attached using the Ez-lock technology. The second type is the sanding discs that employ the Screw Mandrel to secure the discs.

The EZ-Lock sanding discs are entirely flat on the bottom, making them considerably easier to use for sanding flat surfaces. You may also push the complete sanding disc onto the surface being polished.

The screw will be protruding out at the top of the sanding discs that use screw mandrel #402. When sanding, this forces you to keep the disc at an angle.

The sanding discs are valuable to reach those difficult-to-reach acute angles in wood and steel. You can sand at angles steeper than 90 degrees with a sanding disc, which would be nearly impossible to achieve with the sanding drum. 

Sanding discs are also excellent for cleaning metal and metal tools of rust and other contaminants. If you have a rusted antique wrench that you wish to restore, you can use the sanding discs to sand it down to a clean finish.

Dremel detail sanding cones

Sanding uneven surfaces is a difficult task. Detail Sanding Cones are among the most effective methods we’ve discovered for sanding unusual regions. They perform a fantastic job of fine sanding and blending in those difficult-to-reach spots that all wildlife carvers come across regularly. Available in two sizes, each with two grits. The wrapped-paper design reveals fresh grit as the cones wear down, and they’re all quick and easy to change. We suggest using them at lower speeds, around 10,000 RPM, for longer life and more control.

Dremel ez lock sanding discs

The EZ Lock sanding discs are, of course, more expensive. One of the significant advantages of the EZ Lock sanding discs: they have no overhanging parts on the business side and helpfully flush against a surface. They’re also easier to change and, according to Dremel, last twice as long.

Dremel 412

Dremel sanding discs are ideal for smoothing and shaping wood and removing paint. Sanding discs help eliminate rust from metal surfaces and fiberglass. Dremel sanding discs offer a finer grit than Dremel sanding bands, and they give a flexible character that allows sanding in curved and hard-to-reach locations because they attach to a Dremel 402 mandrel.

Wood and fiberglass can be roughly shaped and smoothed with this tool.

Medium 220 grit sanding discs are also excellent for eliminating corrosion from metal surfaces.

For use with the #402 mandrel.

Rotary tool sanding bits

Rotary tools have bits and accessories that allow them to execute various jobs. Rotary tool bits include wheels, points, pads, brushes, and discs for cutting, drilling, engraving, polishing, and sanding. Bits are attached to rotary tools with mandrels, collets, and chucks.

A rotary tool is a portable power tool with a fast-spinning motor tip that is helpful to grind, sand, hone, and polish a wide range of materials. If you have the correct bit, you can use your Dremel tool for sanding and smoothing out wood. Rotary tools come with various attachments for various jobs, making them a must-have in many toolboxes.
