These brushes fall apart very quickly when I work with a dremel. This is very well-known, as you can see from other reviews. To put it another way, I have been able to extend that time by at least 10 times. Very easy. You can add some Duco Cement to the inside and outside of the brush where it goes into its metal holder. There isn’t really a need for epoxy. In general, I set up about 10 to 20 brushes at a time, add Duco Cement, and let them sit overnight before I use them.
For some reason, the brushes stay in and you can use your Dremel for at least 30 minutes before you need a new one.
