Die grinder

[Farm789]

Are cheap die grinder carbide burrs good off eBay or are the expensive ones a lot better? Also is a little bit of oil required with them cause every time I use them I seem to burn the burrs out quick

The cheap ones are cheap for a reason what u doing with them I don't use oil on steel. In got a set from mcs they are on special again this month they are much better than the cheaper eBay ones

 

[Farm789]

Steel also on wood a few times that seems to wreck them. Are die grinders just crap or is it the burrs

It depends what is quick to you.

I only use Garryson Burrs and use them to tidy up steel welds in difficult places so perhaps no more than say 20 mins at a time and haven't burnt one out yet but then I would be surprised if I used them more than a couple of times a month as I hate the splinters. If you are using them continuously all day then I can see how your experience could be different

Literally talking less than a minute and there smoking from new. They cut quick while there new then after a minute or so they start smoking and the metal gets very hot and they don’t cut much at all

Would buy decent for metal work

I use Dormer, they're not exactly cheap but Prime Tools and Zoro sell them and they're not silly money.

Sorry to ask but are you using the correct burr for the material you're attacking?

I've got a set of 6 for £20 - excellent quality, no sign of wear despite moderate use

 

[Farm789]

10 pound ones off eBay 6 for 10 pound

Klingspor

Nearly £20 each but if you’re good to them they’ll last.

Let the burr do the work and oil it where necessary and They’re fine

A good die grinder is a mighty tool , but it needs good burrs , no point in trying to do anything with abrasives or grinding and using cheap and cheerful products , most of them are cheap for a reason.
i use a die grinder for roughing back to silver and digging out underseal and rust and all sorts mighty wee tool , but if you get cheap burrs you will wonder why on earth any one ever bothers with them as they are noisy dusty dirty and loud , but get one with a fresh sharp quality burr and its like the finger of god is at your disposal.

We use Grayson ones we use here - they last a long while.

We also use the bigger 8mm size air die grinders for heavy work.

Always wear safety glasses - burrs throw stuff everywhere.

X2 Garysons oh and glove,those little tiny shards when in the skin take ages to get out

 

[RIP]

I bought a cheap set for £10 and they lasted well. Maybe it's luck depending on manufacturer?

One thing I found is that you really need to keep the speed up - if you let the die grinder bog down (by pushing too hard, or running at the end of a long small bore hose, if air powered) then the edges will chip in no time.
