Brown &Sharpe 9 collets or ER collets

[AR. Hillbilly]

I bought an Index 55 mill with a Brown & Sharpe 9 taper.
I’ve went to order collets and they’re always out of stock.
I’m considering an ER 32 or ER40 collet Chuck and collets instead.
I can find a few B&S 9 single collets.
Is there a benefit to either?

Many old machines use the large B&S collets, there is no reason not to use them- they are beefy, have tremendous grip, and the import ones
are well made- I got a few from Little Machine Shop
Usually for milling machine tooling you would only need a few sizes: I have 3/8", 1/2", 5/8" and 3/4" and use the first two the most

I have an older horizontal mill that uses B$S #9 collets. They've always done a good job and are available from many online vendors. I just checked Little Machine Shop and they have individual items and full sets in stock (11 pieces) in stock

Wells index will regrind it to R8 but it’s very expensive plus shipping both ways.

Thanks for the link.
My old Mill Master uses B&S 9 collets.
I had 1/2 and 3/4 so just ordered 3 collets. 1/4, 3/8 and 5/8".
