These are little milling tool holders I have made for my Sieg KX1 milling machine.

The KX1 is supplied with a 2 morse taper spindle, which allows a range of tooling to be fitted. But one big flaw to this system when using it on CNC machines is that an accurate ‘Z’ height offset cannot be maintained when changing tools. The little tool holders are held in a 13mm ER25 collet which allows rapid tool changes whilst still maintaining the correct tool height offset.

After a few months of machining various material the little tool holders performed very well. Although not up to industrial precision and accuracy they have made using the machine much more easier.
