Eastwood Carbide Grinding Burrs
 

i've had a hi-speed(24000rpm) die grinder for about 30years have always used inexpensive grinding stones from sears and swapmeets with pretty good results/// so why did i spend close to $70 for these eastwood carbide??hate to say it but i succumbed to the barrage of catalogues over the years

first off i chucked them up one at a time in the die grinder and each and every one of them are so out of balance i can hardly hold on to the tool much less grind anything with it,, trying to use them with my airdrill maybe 4500rpm the vibration was somewhat less but still very noticeable, they really weren't very effective in smoothing the metal although they do remove some metal .. i figured that to get the same finished product using these eastwood crappy tools would take 11/2-2hours compared to the 10-15 minutes with the elcheapo grinding stones

note to self!!! call first thing monday for refund and return

IF YOU CAN BUY IT FROM EASTWOOD YOU CAN GET THE SAME OR BETTER FOR LESS MONEY THEY'RE JUST SELLING CATALOGUES THEY DON'T MANUFACTURE ANYTHING EXCEPT SPIN

Even though Eastwood isn't too far away from me I never bought anything from them. As far as carbide burrs go, I have bought from http://search.ebay.com/_W0QQfrtsZ50Q...mmQ5ftools8rx7 . Long lasting and good quality. I primarily use them for head and block work. Single cutters for aluminum and double cutters for steel, cast iron. Never really use stones, myself.

how many rpm's do you spin those at ??? any vibration problems???

Re: Eastwood Carbide Grinding Burrs
 

I would guess I'm spinning them around 5000-7500. Even at top rpms around 22,000, I have to wobble or vibrations. You could probably email him and ask. Even if one of my longer burrs go out of balance, they reset after applying them again. No complaints here.
