ER25 Collet Blocks

[Deko]

I do'nt know if i will be in trouble for posting this , but,  when John S made his ER32 blocks, i know the cries were long and loud for ER25 versions. Well your cries were heard, and guess what !!!!  They are now ready. I have no connection with the suppliers so nothing for me to gain.

Hello HS & Deko,

Are the blocks larger than the OD of the ER25 nut, I might be criticised here, but I prefer the block to be clear.

What I'm going on about is, when holding, say a 4 fluted cutter, for touching up the cutting edges, I don't want the nut to hold the block off the grinding table, whilst off hand grinding.

I bought the 5C ER32 adapter and blocks, I ground another 2 flats on the 5C adapter flange, to clear the table, but ended up using a spacing flat bar anyway, to clear the nut.

Hi Chris
             I think this is a case of "you can please some of the people some of the time Etc."  I do'nt have the ER25 blocks so i ca'nt answer your question re those, However on the ER32 blocks the nut does extend beyond the block faces.  Most folk, including myself think this is a usefull feature as when using the blocks horizontaly in the vice, the nut acts as an indexing feature. For example when milling a square or hexagon on the end of a bar.
