Rotary tools are one of the most convenient tools you can use for sculpting and carving purposes involving wood and metal with the Dremel rotary tool being one of the most popular tools being used in the world today. With most rotary tools being compatible with a lot of rotary tool bits in the market already, sometimes you would want to modify an existing tool bit or make a new one from scratch. Bearing in mind that it may not be possible to modify or make every tool bit you imagine, building some of them yourself can be cheaper than buying a new one and can turn out to be a fun activity too. Below are a couple of rotary tool bits you can build yourself with step-by-step instructions and the tools and materials you may need. 

Polishing Wheel 

Step 1 – Cut Satin Circles 

Using scissors cut several 2” diameter circles out of the satin cotton sheet 

Step 2 – Tie the Sheets on the Rotary Tool 

First attach the sanding bit onto the rotary tool. The sanding bit is the one that is kind of rough and looks like a little drum. Fold the several satin circles over the sanding bit and tie them around it using the metal wire. Make sure you tie them real tight. 

Step 3 – Test the Simple New Polishing Wheel 

Turn on the rotary tool and test your self-made polishing tool attachment at variable speeds to see if it is tied well enough. You now have a brand new polishing wheel that will be as effective for buffing as doing it with a company-made one. 

Double Dremel Buffer 

Step 1 – Prepare Yourself 

Put on your safety goggles and hold the threaded end of one of the wood nails with pliers. They will be getting really hot when you move on to the next step of the process. 

Step 2 – Cut Off the Nail’s Head 

Use the metal-cutting emery wheel to cut off the head of the wood nail very carefully.  

Step 3 – Smoothing out the Nail 

After the nail-head has been cut off, use the metal file to smooth out the rough edges that may have formed around the tip of the wood nail.  

Step 4 – Attaching the 2 Buffing Wheels 

Attach the two buffing wheels to the wood nail by twisting them onto the threaded end of the nail. This threaded end is the part that will be going into the Dremel rotary tool after you’re done. 

Step 5 – Insert Your New Double Buffer into the Rotary Tool 

Simply screw in the wood screw with the double buffing wheels into the rotary tool. You have a brand new double buffer that you made yourself!

You have successfully made yourself a new rotary tool bit.
