Shars R8 solid tool holders, are they any good?

[fusion_crank]

Hello all!
I have a questions for you. I would like to get some R8 solid end mill holders. I have looked at them on the Shars web site. The price is great, but they don't specify what the bore and runout tolerance is. I emailed Shars to ask about this, but go no response.

So, has anyone tried them? If so, what did you think of them?

Thanks!
Mike

you must have low resolution on your monitor, try scrolling to the right.

Size: 1/16" - 1"
.0006" TIR
Drawbar Thread: 7/16"-20

Never tried them but made in the USA, Id give them a whirl.

I see the TIR on the collet description but not on the end mill adaptors.

I thought it was just me who couldn't see it. They have a spec on the collets not the adaptors.

Well, I called Shars and they said they don't have a spec, and they are "shop" grade.
I hate gambling. So I guess I'll just stay with collets for now. Unless someone who already has them will speak up.
Thanks guys,
Mike
