PUNCH SIMILAR TO DIN 9861 SHAPE C Description: DIN 9861 restricts the range of stepped punches with conical head to shanks of 3 mm max. diameter and points of 2,95 mm max. diameter. Stepped punches of larger size are, however, quite popular owing to their rigidity and ability to sustain considerable stripping forces. In accommodation of this demand we supply larger sizes whichare ground from stock sizes of the 223.-series Please select from those ranges and complete your order in accordance with the example on the right.
