Boehm JLBM50PA Stepped Chuck 2-50mm
JLBM50PA - Chuck for 2 to 50 and 1/8'' to 2'' hollow punches
This chuck allows the locking of JLB model hollow punches up to a diameter of 50 mm or 2'' which ensure the cut-out of pellets and washers in a concentric way and in a single operation thanks to the spur system which allows the pairing of two hollow punches.
This chuck is used when screwed on the JLBM53PA handle (a setscrew ensures the locking of the chuck on the handle) press or laid down flat with the cutting edge of the hollow punch inclined upward for cutting with a mallet. Warning: the JLBM52 handle cannot be assembled with this chuck.
