Grinders

[Sandy]

Just discovered a conventional off the shelf wire cup won't screw onto my HF cheapo. Kick in the head. Must be metric or something.

Of course I don't buy the HF wire anything, so I can't testify if those fit or not.

Hmm, that is odd. I thought the head was a standardized size?

Me too. Just tried a different wire cup a bit ago. Didn't fit :) .. Could be a 'per batch' thing on their grinders, maybe not. Sort of changes my perspective if this is a normal thing for those HF grinders. I don't like non-standard when it comes to those types of tooling. :)

Do you have the super cheapie blue grinder or the more expensive orange one?

If the blue one, I have the orange and I'll try it on mine and let you know if it works.

It's an orange 41/2". Not really sure what model. Lil woman bought it for me. She always thinks she's doing big stuff when she buys things for me, soooooooo :) ..

It could be it is part of a run normally made for distribution in other countries, or it could be all of that model.

Okay - I have both orange in the 4" and 4.5", I think they have the same stud, I'll check and let you know.

I have the orange 4.5 and it takes a standard wire brush. I have used several different brand wire cups and wheels with no problem.

Practically speaking, it's defective. I would take it back if they can show you a wire wheel or cup that fits fine buy a few. If not it's defective and they should replace it.

I have the 4.5" elcheapo blue and I use a 4" Dewalt wire cup on mine just fine.

HA!! Found an ancient wire cup in a drawer of my radial arm saw that fit. Actually more like a nub, not much wire there. Came off of a long time dead and gone makita I think. The nut had a stamp you could read through the rust, it is 14mm by whatever thread pitch. Bingo, so it is sort of standard. Standard for the early japanese models that flooded our market years ago.

My wild gues is that stud/insert is in all ways the same except for the market it is destined for, then the size and thread pitch is different. ????

Any way I'm not quite so bothered now. That 14mm is fairly common if you look around. Getting less so as time goes on. Just means the threaded (5/8thsx11) grinding wheels won't go on there. It still has the comparable 7/8th" collars for everything else. :)

Thanx Micro. :)

pssst, if it's a recent purchase or gift and is still sort of new and you maybe still have the box and papers, just take it back and exchange it for the same model with the 5/8-11 threaded shaft. reason - wrong threads on the shaft because the wife didn't know there was a difference so you'd like the model with the same shaft threads as your other tools.

Or just deal with it and find/buy/use the metric threaded 'stuff'.

IIRC, I have an orange 4.5" and it uses 5/8-11 'stuff'. Same as my other grinder(s), so I don't have to pick through or buy different 'stuff'. One thread size so it all fits and works on whatever grinder, no fiddling or picking through or cursing because you just jammed the wrong threaded cup brush onto the grinder.
