Repairing your "High Speed Steel" setting bur - 7 photos

 This essay was posted in the MJSA magazine July-2024. This time you are seeing the photos up close in 'our' blog.

 Here is a badly worn bur through many weeks of continual use. This "High Speed Steel" bur has cone in contact with hard gold and the edges of the teeth have gotten badly worn or broken off. Don't throw away these expensive steel burs, you can now easily repair them.

 I first darken the bur with a coloured pen, this will allow me to see which tooth I'm going to be repairing.

 With a "Separating Disk" that is 7/8th of an inch in diameter. I will very carefully apply this rotating wheel to EACH TOOTH OF THIS BUR. Only the fine edge of each tooth will be touched, not the whole tooth. This is a time-saving process.

 When the new bur has been repaired, PLEASE BE ADVISED that 'every fixing' changes the diameter of the repaired bur by small increments. These changes are not noticeable at first glance, but they are changed by measured mm's.

 There is no need to repair the whole tooth, as the 'initial contact spot' is only at the edge of the bur as shown in this photo.

 The 'separating disk' renews the 'contacting spot' for future gem stone setting. Thus saving you loads of 'hard earned' money. Many of my inventory of HSS burs have been repaired in this manner.

 I didn't feel that a long text essay should be needed. I just wanted to show the salient facts of this 'repairing process'.
