I've just bought myself a set of ER11 collets that will fit in a 1MT chuck for my milling spindles. I already had a couple of ER11 collets and a chuck with a parallel 16mm shank and an internal JT1. However the compactness of the 1MT chuck offers major advantages for both milling and drilling. The chuck and the collets came from 2 different vendors. There are 13 collets in 0.5mm increments from 1-7mm
.
Keeping the collets in their little yellow boxes is not very convenient, yet because of their small size reading the collet size is next to impossible. So I need to make a box for them.
I have some nice old beech wood salvaged from an old piece of furniture. Look away now, Jo. The holes are 27/64" and the chuck recess milled with a normal 4 flute endmill at my highest speed of 2000rpm
The middle row houses the whole numbers and the top row the half sizes. Numbering the middle row allows me to identify which is which. The parallel acts as a guide for the number stamps, which I have carefully arranged (and double checked) so that I get the correct stamp and in the correct orientation. These are my largest stamps at 1/8"
Filled in with pencil and a quick rub with sandpaper
The lid is glued up from 4 more lengths of beech and some birch ply
A quick coat of danish oil to keep the worst of the grubby fingerprints at bay, some furniture from the local hardware store and the job's done
Thanks for looking,
Rod
