Abstract: A manual machine tool (10) with a housing (12) that carries an adjustable bit stop (32), particularly on a supplemental handle (28), becomes more convenient and safer to operate because the bit stop (32) can be fixed in positive fashion, particularly in latching fashion, next to the manual machine tool (10).
