What would you use a burr like that for? What's it's stated purpose?

midnight,
thats what i am asking,i am thinking it might be easier using this shape burr to shape the short turn and if anyone has tried this shape burr or any ideas,i only received them today and i will try them this week,

I used burrs like that for the ssr, but found they don't work that well. A 5/8 oval or egg works better. In fact a 5/8 oval bit works best for everything.

Joe,
thanks for the tip,i have both of the burrs you have mentioned but figured the 5/8 oval would be to big but you dont know until you try i guess lol

Bigblock,
bought them off Amazon USA $ 61 delivered,i suspect they are cheap quality but again i want to try the shape,i tried a reverse cone to work the SSR on chevy cast heads but i cant get a good finish,i used a small egg with long shank and worked well for me but joe gave me a couple of tips and i appriciate any help

I use electric die grinders. One has a variable speed. I just use it on a lower speed with a regular burr when doing touchy areas like the SSR.

Steve,
I bought a couple of these and other shapes from Circofile. I thought that these would work on SSR but didn't get good results. Eggs and reverse tear drop shapes worked best. Circofile have a website and have great prices and service. They will sharpen burrs as well although I haven't done this yet myself. Good bloke to deal with, family owned company with great products. Was recommended to me from this forum.

Looks like it should but would think in reality you may be frustrated.
Always used the largest burr you can,lower the speed, more control-less chances for mistakes.

[JoePorting]

I always liked around 10,000 rpm's or less. Too bad 99% of die grinders are 20,000 rpm's or higher.

Joe, thats why mankind made air pressure regulators. NOT trying to be a smartass, so please don't take it that way. Mark H.

Or a VariAC

That.. or simply slip a gloved finger under the throttle to act as a throttle stop for controlling rpm.

[swampbuggy]

Yea Groberts101 done that. One of my diegrinders (AIR) currently has a piece of 1/4" thick black sheet rubber affixed under the lever to prevent over speed, while at the same time gripping firmly enough to control the grinder. Someone may wish to try this idea, i am sure i am not the first person to do this . Works for slow removal when you are getting close to finished. Mark H.

I have an old Shinano die grinder with a vane that has a piece broken off one end. Should put new vanes in it but it works a treat for finishing the SSR. I use other grinders for the roughing out. Don't have to change burrs on that one either.
