Advanced Material Durability for Aluminum Work
Despite its slim profile, the sash punch is built for extreme durability. Forged from high-tensile 42CrMo alloy steel, it is designed to withstand the repetitive high-cycle production common in aluminum window fabrication. The tool undergoes deep induction hardening (HRC 48-52), ensuring that the punch tip maintains its sharp profile even when processing hardened architectural-grade alloys or galvanized steel.
