Chris's Tips
Most Chinese mills come with metric threads on the drawbar. However, the Morse taper tools we sell have "inch" drawbar threads. This is because we could not find a reliable supplier of tools with metric drawbar threads.
You might need to a make or purchase a drawbar to work with these tools.
With all ER collet chucks, the collet must be snapped into the nut before placing it into the chuck. There is an eccentric ring inside the nut that engages the groove in the collet. That is what makes them self-ejecting. Tilt the collet again to remove it from the nut.
This shows the sizes of all the ER collets we carry.
