Morse taper arbors for hole saws with coolant feed

Designed for mounting annular cutters for metal with a Weldon 19 shank on magnetic drilling machines and stationary drilling machines with an MT2/MT3/MT4 spindle
The annular cutter is inserted into the holder by its shank
The retaining ring secures the fitting that connects the holder and the coolant reservoir with a tube
The ejector pin opens the coolant inlet valve inside the machine holder to cool the drilling area from the inside

Installation and mounting features:
For a cutter with a Weldon 19 shank: the shank flats must be positioned opposite the internal hex screws. The screws must be tightened as far as possible
For a cutter with a Universal 19 shank: one screw must be pressed against the flat, and the other tightened slightly.
If everything is done correctly, the cutter must not move or turn inside the holder!
