ALFRA Split hole puncher TriCut®

The ALFRA TRICUT was the first three-splitter on the market. The cut piece splits into three parts and therefore no longer jams in the die - for burr-free cut-outs.

The TRICUT can be used up to a material thickness of 3.0 mm on sheet steel (19.0 mm tension screw or tension bolt; 3/4‘ UNF fine thread), up to 2.0 mm with 9.5 mm tension screw or tension bolt (3/8’ UNF fine thread) or on sheet steel up to 1.5 mm thick with 6.0 mm tension screw or tension bolt (M 6).
