Popular Cleaning and Polishing Flex Shaft Attachments Used at Your Jewelry Bench

All About Flex Shaft Attachments

A flex shaft (or Dremel) rotary is one of the most indispensable metalsmithing tools in the jewelry studio. We use flex shafts for sanding, polishing, cutting and drilling. They shave time off in the studio so we can move on to other projects. I love our flex shaft but the attachments can get complicated, especially for a beginning jeweler. I’ve broken down the cleaning and polishing attachments that we use here in our studio. Feel free to print them to hang up in your studio if you would like.

These are the two charts that I refer to the most…

1.) Cleaning & Finishing

Our wheels in this category vary from cleaning to finishing. Use polishing compounds only on the wheels and felt bobs marked in the chart below.

X594: Flexible Satin Finish Wheel – I love this attachment when putting a satin finish on my jewelry, however, the bristles break off so I highly recommend long sleeves and an apron!

X512: Felt Bob Polishing Set – For a mirror finish use this set with compounds. The set includes a whole array of different sizes that will fit into all kinds of nooks and crannies. The veins on the item to the left have a mirror finish which is nicely offset with the laser cut imprint.




2.) Radial Disks

We carry 3M bristle disks that have a multitude of uses from sanding away fire scale down to fine polishing. Think of these disks as a sandpaper set, from coarse to fine. You need 3-5 disks for every mandrel so I suggest having one mandrel for each disk type to save yourself from having to change them every time you change grits. Be sure when you mount them on the mandrel that all the bristles are facing the same way and they’re all turning toward the right when looking at the top of the mandrel. Follow the chart below from top to bottom to achieve a mirror finish. If you haven’t used these, they are sure to become your favorite flex shaft attachment. You do not use compounds with these disks.

Note: Do not keep the disks on just one spot on your jewelry, you’d be surprised how quickly they can remove material!
