Patented system for locking the spindle collet of the BOSCH 1200-1400 Ace milling machine, via convenient Allen screw above the plate.

This system is compatible with all plates on the market, you just need to create a hole to match the exit of the Allen screw.

You can also apply my system if you use the supplied intake duct.
