HOW CAN YOU Repair ("High Speed Steel") HSS burs => 20 DETAILED photos

 Let's just start with a recently seen photo, the bur in question is a sharp-toothed HSS bur. You want loads of instructions with details? Here they are!

  What is seen here is a row of well-worn teeth; they need immediate repair, but how is this to be done?

 It appears that there have been some alterations done to this bur, but how?

 

  There are still some chances of metal cutting remaining to this HSS bur, but not much!

 These teeth have seen 'better days', but now they are just not suitable for extensive & advanced stone setting.

 

 Assessment of this particular bur shows me that every bur tooth needs to be 'totally recut or reshaped'.

 

  This photo displays the end result of individual reshaping of EVERY tooth. I will show you the exact process needed, one step at a time.

Every tooth in these burs in this bur-box requires a few 'touch-ups', but not extensive recutting.

 Every bur that needs recutting should be 'darkened' as this will give you a chance at deciding which tooth has been 'touched'.

 

                            HOW IS THE REPAIRING ATTEMPTED?

 This whole process starts with 3/4inch diameter "Separating Cutting" Disk. Then the wheel is affixed on to mandrel.

 There is no need whatsoever to repair the whole bur tooth, only where the cutting contact is needed.

 Blacken the teeth on the bur; if you don't do this, then the repairing will be difficult to ascertain which tooth was even touched.

  Now comes the easy part: when the Separating Disk is rotating (at a slow speed), make contact with that one tooth.

 Starting at the 'mid-point' on the tooth, and running it towards the end of the bur. 

 I could suggest digging a bit deep on the cutting. Why is this? You MUST CUT DEEP INTO THE METAL, AS THIS WAY THE WORN TOOTH IS REPAIRED. 

 This is just where the 'repairing is starting'. The 'contact area' is the middle of the tooth, nowhere else! 

 If the 'underneath' section of the bur requires similar repairing, then you may do it at this point.

 Don't forget to paint that underneath section as well. This will greatly assist you in finding which tooth needs to be 'touched'.

 In repairing the bur, there will be a slight difference in the overall diameter of the bur. This is a normal occurrence and don't be overly alarmed, this will happen all the time, trust me on this!
