Please see the attached picture. The tool on the right is a 1" endmill holder and it WORKS in my quill. The one on the left is an ER40 volley holder that I just ordered and received (i bought 2, only opened 1 yet). This DOES NOT WORK in my quill.
You will see the difference just south of the taper. There should be a "flange" about 1/8 thick created by a turned groove on the other side. Not sure if I'm being clear, sorry.
The new ER40 holder does not have this groove. South of the taper it just turns into the tool body.
My question is, is there any allowance for this? Can they really call this "NMTB30" if there is no groove on it? It looks to me like they missed a step in production but maybe not all NMTB30 are created alike and this one just happens to not work in mine. If it's defective I'm sending it back. If there is actually nothing wrong with what I bought, I need to decide how to go forward.
