The taper shank arbor according to DIN 238 connects the machine spindle with the tool clamping head (e.g. drill chuck). It has a Morse taper MT4 with flat tang (ejector tang), which can be picked up by the machine (e.g. drill press) and a taper B18 which can be picked up by the drill chuck. At the end of the Morse taper is a flat tang (ejector tang) (standardised according to DIN 228 part 1) through which the taper shank arbor can be easily removed from the spindle without damaging the machine spindle.Our taper mandrels are fully hardened and precision-ground to enable high precision, strength and long tool life time.
BAER taper arbours enable efficient and precise machining of workpieces through their connection to the drill chuck and are indispensable in the metalworking industry.
