Mark,
Got a set of the screw removers, they are made for woodscrews but will work with rounded countersink allen screws.
Used them a few times and all but once got the screw out.

Can't comment on the diamond blocks, seen them but never used them.

The screw removers don't look useful but I'm going to get one of those diamond blocks for a try. Aldi stuff is usually junk but every so often they bring up a little gem so maybe this is one of those!

the cheapo diamond coated stuff isent half bad. It works much better wet however, Else it seems to clog up, And its much more for sharpening tools/knifes/etc then it is for roughing. Works well on brazed carbide, as long as you have not chiped it.

[Evan]

The best screw removing tool I have found is a small tube of silicon carbide grit paste meant for the purpose. Valve grinding compound should work just as well or some crushed up grit from a grinding wheel in grease. Apply to the screwdriver and if there is even a trace of the original slot/socket/head/whatever the screwdriver works like the head is new.

It works with anything, even wrenches on rounded nuts.

Here is the real thing, apparently available everywhere. It works as they claim.

I've used carbide lapping compound like this as well.

Mostly I just use a left hand jobber drill.

Is using grit/laping compound bad for your tool? it seems to me if it sliped at all, you would end up grinding your tool head down a little.

I believe they were talking about another kind of tool.

I bought a set of screw removers from Sears. They are double ended, a drill on one end and a gripper on the other. They are 1/4" hex, so made to be used in a cordless. They have worked well for me, although I haven't used them a lot. Now it looks like Sears just carries ones like the OP's photo.

Got to use the Aldi one today ..

verdict ..
a pile of crap ..

Just spins around in the cross head ..doesnt cut and grab ..think its made for soft screws.

may work on a milling machine ..

i couldn't put excessive force on this screw its in a bad place ..which is the reason i chewed it in the first place ..

anyway ..after it slightly mangling the head ..i was able to put the pozi bit bit in the driver and remove it .

The diamond block is junk too. Looks solid but it's just thin diamond-coated sheet on a plastic block.

The diamond block is cheap junk, but it works really well for knife sharpening. I have used the same cheap ones for years. The best way to use it is to thin down the blade with the diamond, then use a hard Arkansas or ceramic stone to lightly do the final razor edge. It only takes a couple of minutes to get a very sharp edge this way.
