Hi,
I've got a Stepcraft machine and a MM-1000 spindle.
I have the clamping nut that came with the spindle, which has a neck of 15mm and a hexagonal top part of 5mm, 20mm total.
You can see it here
I want to buy an additional clamping nut so that I don't have to change collets when I want to change toolbits. I found this one here for example...
Is it okay to use it, even though the neck might be less than 15mm?
Can you recommend a good one and where to buy it so that it is safe to use with the MM-1000?
Thank you
