Ferrule Crimping Tool Kit AWG 28-5 - Self-Adjusting Ratchet Crimper

In this review the Preciva ferrule crimping tool kit is evaluated as a practical, all-in-one solution for anyone who regularly terminates stranded wire. The kit combines a self-adjusting ratchet crimper with a large assortment of ferrules and a portable storage box, which makes it useful for electricians, hobbyists and maintenance technicians who need consistent, reliable crimps without swapping dies. The single biggest reason to buy is its balance of convenience and performance: the tool reduces hand fatigue while delivering snug, repeatable ferrule crimps across the AWG 28-5 (0.08-16mm2) range.

Key Features

• Complete kit: Includes crimping pliers sized for AWG 28-5 (0.08-16mm2), 950 single ferrules and 350 twin ferrules in a double-layer storage box for organized portability.
• Labor-saving handle: The bow-shaped handle with a flexible shaft offsets pressure to reduce hand force while keeping crimp strength consistent.
• Self-adjusting ratchet: The ratchet mechanism ensures secure, uniform crimps without the need to manually set die gaps for each ferrule size.
• Anti-jam jaws: Limit points added to the jaws prevent over-closing and jamming for smoother repeated use.
• Adjustable crimp force: A star disk lets the user fine-tune pressure to match different wire thicknesses for precise crimping.

Who It's For

The kit is well suited to electricians, field service technicians and makers who terminate stranded wires frequently and want a tidy assortment of ferrules on hand. The included 950 single and 350 twin ferrules cover many common wiring needs, and the portable box keeps parts organized on the job.

It may be less appropriate for users who only crimp very occasionally and prefer buying ferrules separately, or for professionals who require interchangeable crimping dies for non-standard terminal types not covered by the hexagonal ferrule die.
