DIAMOND Cordless Metal Puncher 15 mm (EPC-1525W)
High-Performance Cordless Metal Punching for Construction and Fabrication Applications
The DIAMOND EPC-1525W Cordless Metal Puncher is a lightweight, portable punching solution designed for electrical contractors, steel fabricators, and construction professionals requiring precise hole punching on-site. Powered by the HiKOKI MultiVolt 36V battery system, it punches round holes up to 15 mm in diameter and elongated holes up to 11 × 16.5 mm in steel plates up to 6 mm thick. Its cordless design provides excellent mobility, allowing operators to perform metal punching tasks without the restrictions of a power lead.
Engineered for reliable performance and ease of use, the EPC-1525W features a double-acting hydraulic cylinder that helps prevent the punch from sticking during retraction, enabling smoother tool removal from the workpiece. Its 360-degree rotating head provides flexible positioning in confined or awkward spaces, while the included stand set supports stable operation. Weighing just 7.5 kg including the battery, this compact tool can deliver approximately 350 punching operations per charge under the manufacturer’s test conditions, making it ideal for electrical installations, steel fabrication, and demanding on-site metalworking applications.
