Cup bur question


#1

Hi guys :~)

I need a new set of cup burs and I want to try a different style. Can anyone give me feedback
regarding these two designs?

Many thanks!

I would pick the Busch bur, why? You can actually ‘see’ what is taking
place during the removal of the metal on the tip of the claw/prong!!! I
like this version better, as the ‘teeth’ are right against the edge of the
bur. Unfortunately, the next pattern/design the deep-cutting teeth are more
"aggressive" in the cutting process. Plus, the teeth are not truly against
the edge of the bur. Much “modification” needs to take place & not cost
effective!!! Hope this review is helpful.
Regards!

Hello Gerry,

Thank you. I will be using these burs to use primarily on the ends of wires.

A small barrett file. Skip the cup burrs.

With Barrett files, your ‘claw tips’ may not be ‘finished’ perfectly
round…just my opinion!!!

I go thru lots of cup burs and prefer Busch Fast Cut.

Hi Jeffery

I have only been using concave twin cut burs since they came out. They cut faster, don’t load with metal and stay sharp longer.

hi Jeffrey,

I just got my hands on the book “Magnificent Tiffany Silver”…and was thinking of you…!..then I got to wondering…on tea pot handles…are the ivory discs to keep the handle from getting hot…?

I agree 100%, as would my wife, aka my first earwire “victim.” :head_bandage: It’s so much easier to make fast, consistent, smooth ends with a cup bur. That being said, though my breadth of expertise is limited, I’m not unhappy with the regular LYNX burs from Rio: https://www.riogrande.com/Product/LYNX-Cup-Bur-Set-of-12/344365, so perhaps their C4s are reliable as well.
