Applicators Built for Every Termination Requirement

Diamond Die designs and manufactures applicators to support everything from signal-level terminals to heavy-duty EV and battery cable applications.

Applicators Engineered for
Every Terminal Type

Diamond Die applicators are purpose-built to match terminal size, force requirements, and production demands. From high-speed signal-level terminations to heavy-duty EV and power cable applications, each applicator category is engineered to deliver consistent crimp quality, reliability, and long service life.

Hi-Speed Applicators
(Signal-Level Terminals)

Designed for precision and speed in signal-level terminal applications.

Hydrofeed Applicators
(Medium-Size Terminals)

Ideal for mid-range terminals requiring controlled feed and consistent performance.

Heavy-Duty & EV Applicators
(Large / High-Voltage Cables)

Engineered for large-format power and EV termination environments requiring greater force and durability.

Professional Hand & Hydraulic Tools

For bench work, production environments, field service, and repair, Diamond Die supplies professional-grade hand and hydraulic crimping tools built for accuracy and repeatability.
